Title: Eco Eye PV Smart
Post by: bjp11scot on December 09, 2011, 08:54:35 AM
Hello Good People
Does anyone have any idea when this http://www.eco-eye.com/products-smartPV.html is coming?

Does anyone consider there is an alternative at this proposed price

This looks very interesting. I think there will probably be quite a few similar devices launching shortly for us Inverter Addicts!

Still only seems to use clamps with no ac voltage signal to obtain the power factor and current flow direction so I guess accuracy will be no better than 80%

Beware. I bought a single clamp meter device for the input and find it is confused by the presence of the inverter. It implies the inverter consumes power at night which is refuted by measuring the consumption meter. I think meters using sensors counting flashes from the accredited meter will be much more accurate. :-\

According to the manual that came with my inverter my inverter uses < 2 W 'internal consumption during nighttime'!

I agree with Paul above. Mine is ordinary Eco-Eye with follg results-

1. Clamped on the 'usage' cable, it shows sensible rises from zero up, while switching on succession of 20watt bulbs.  :)

2. Clamped on net import/export cable, it  would not go anywhere near zero when I tried to balance usage with generation. banghead:

Fortunately , the flashing Generation meter did agree with the Sunnyboy which restored my beleif in Sunnyboy :)

60 watts on Sunnyboy; when flashes were about 1 per min ( ie 60 per hour ie 60 watts).

Post by: Ben55 on December 09, 2011, 07:30:02 PM
I'll add that I think there must be a noticeable phase difference, so it was impossible to get  near zero when I was  trying to balance  usage with generation power.

And you cannot tell whether the value is import or export.
 
In summer, with much bigger values, it should work better :)

I have a Wattson energy monitor which implies my Power one inverter  / soladin /windmaster 500/ collection of OK4e micro inverters use a total of 97 watts continuously at night. I do not believe they do  !!!!!!!
Problem is it deducts this 97w from my usage as it believes it's a generated figure so my usage in the evening looks good. Roll on an easy to install device that counts meter flashes - the only honest way of measuring consumption and usage.

OK being a bit of  novice to all this - are we concluding that the suject 'eco eye pv smart monitor' is no use and serves no useful purpose???


Title: Re: Eco Eye PV Smart
Post by: Ben55 on December 10, 2011, 04:06:12 PM
Well I do like my EcoEye when the sun rises and the generation increases by hundreds. :)
The big display is easy to see, as you walk around the room. Or carry it about.

I have to remember that  can't add or subtract properly for values below 100 watts.
It doesnt know the phase factor which seems to make bigger errors there; Maybe other sources of error like electronic noise.



Title: Re: Eco Eye PV Smart
Post by: Automan on December 10, 2011, 04:42:17 PM
The Brultech system from Canada and TED for the USA seem to be the only products that can display accurate data (and know the power factor and which way the current is flowing).

Brultech however seems to need a PC on all the time to save the data which is output up to every second (available in UK but have to order from Canada).

TED should be better as it has nice display units so I don't think a PC needs to be on all the time (UK model however several months overdue).

Other snag is both system cost three figures.

Hi Everyone,
I am Peter Longley, Technical Manager at Ecp-eye.
I have had a quick read through and thought  I could give you some answers.
SmartPV will be on sale 16/1/2012 and will be £86.40 including VAT.
For that you will get:
Transmitter,
2 current sensors
1 peak voltage detector
Smart display
Memory card (recording at 4 second intervals)
USB cable for real-time output, firmware upgrades etc.
Trax - computer program for Smart - at the moment only Microsoft Windows but Linux and Mac will follow soon.

The two current sensors clip round the neutral on the PV and the neutral under the main meter. the peak voltage sensor is wrapped around a live cable. Plug all this lot in and you will get a readout of generated, used or nett together with a flashing green (surplus), red (using from grid) or yellow if the two are about the same.
The peak voltage sensor allows us to deal with the problem of inverters going out of phase at low inputs and improves the accuracy greatly
.
We intend to keep developing both Smart firmware and Trax as users tell us what they want. There is a wifi module coming soon and around Easter there will be appliance modules that can be controlled by Smart.

Hope that helps  - any questions, just ask.

Good luck
Peter

I'm not technically minded but this looks like what I would like ... this will show what I'm generating and what I'm importing... when to put the dishwasher/washing machine on, or more importantly when not to put high load things on .. I use an average 10 Kw a day so any help would be good.

 
Could the monitor be away from the meter by about 30ft ?  is it blue tooth?


I have generated 144 kw since my install on the 11/11/2011  I'm a happy bunny we are not south facing and the sun has gone to the side of the house just after midday  :( but spring will be better exhappy: .. roof is about 40 deg  .. 16 Sharp 245 panels

The SmartPV transmitter and display are linked by 433Mhz radio - so 30 feet should be no problem.

I have the eversolar solareye.The solar bee (transmitter) just goes in the ethernet port of the inverter and wirelessly transmits the data to the eye,seems good to this novice but it wont stay displaying data for more than a few minutes until i press a button which is a bit annoying for a pv watcher!

Hi Peter

Always good to get information straight from the horse's mouth. I think I'll be investing in the PV smart when it becomes available - sounds like a useful bit of kit.

I do have a question about our Eco Eye Elite. It's hooked up to the ac from the inverter.... so why does it show 70W when it's dark?


Cheers

Nick


Title: Re: Eco Eye PV Smart
Post by: Peter_L on December 15, 2011, 04:36:48 PM
Hi Nick,
Common problem - the inverter goes "out of phase" at low to zero input which confuses simple energy monitors. This is one of the reasons that SmartPv will have an extra sensor to detect the phasing.

We have seen similar problems with microwaves, hairdryers and other pieces of equipment that appear to use more power when unplugged!

Peter

Peter - you say that there will be two clamps for the two feeds. How will you cater for those of us whose meters/feeds/consumer units/JB's are not near each other?

Any chance of wireless transmitters from the clamps?

The mains input to the house arrives under my stairs, where the leccy meter is; this is where I clamp or pulse read on the 'Current' setup, via a wireless xmitter, because:
the PV inverter/meter etc is in the garage, where there is a second consumer unit, and where my second clamp/pulse transmitter is. Unfortunately, there is no practical/user way of using cables/extensions between the two locations, hence the query about wireless xmitters.

Hi Lee,
As long as the cables from the inverters get joined together near the meter that should not be a problem. One of our beta sites has 2 inverters.
Initially live output is to a windows program but there will be a wifi module that will allow access from mobile devices as well as a number of other networked services without the need for a computer.

Hi Andy,
If there just one cable coming from the garage to under the stairs then I do not think it is going to work. I would need to have a look at a detailed wiring diagram to be sure.

glad to see all this activity re using excess power. I`ve been looking for this sort of thing for a while to make sure that in winter all unused power from 5.5kw waterwheel goes into useful heating. I`ve been planning to  make an immersion heater/boiler of 6kw and plumbing into existing wood fired ch but the control unit has held me back ( i thought of using an old disc type meter as a current direction sensor).
 Hope that an idiot version is available in time for next winter.
Keep up the good work.

It should do. 

You do not click the green arrows, you 'click-select' your inverter in the left pane and then click the right pane - inverter 1 if you have just one.

Click the movie icon at the bottom of the first setup instruction pane for a sample video of setup.

In the right pane, you can also edit the installation name.

It's a different PC-Link for the 600, so check that you have the right one.

We have decided that we will unfortunately have to delay putting SmartPV on sale again.

This is due to manufacturing issues that affect the radio and recording to the memory card.
 
We apologise to everyone who is waiting for this product but we promise you that the wait will be worthwhile.

Looks like its delayed for a while longer - no date supplied for when it may be available. :(

@Peter_L

Hi Peter looks like a good product but to be useful the display output needs to be convenient to view and for me that means it is not near a computer.

When the full spec is available will the following be possible:

Consumer unit and Solar inverter are together in the garage.
Eco-Eye display located somewhere in the kitchen/lounge.
Computer located in the "office".

Will/Can communication between the three locations be wire free?

My Computer currently uses bluetooth to connect and gather data from the inverter and it would be rather inconvenient to have to (remember to) move the Eco-Eye unit every few weeks to "save" the data and view the analysis. Much nicer to have it all happen automatically when one wants to view the stats, especially as according to the web page it only has 64 days of data storage and it looks like you have to take the card out to read the data. (optional accessory is a card reader).

Or have I missed something...?

Hi
Locations are fine.
Readings are buffered and written to the card approximately every 8 minutes. You can extract the data to your computer as often as you like, I tend to do it every couple of days. The Smart display is battery powered so can be moved around so you could take it near to your computer but as long as you get the card back into the Smart before it needs to write you will not lose any data.
The 64 days relates to the daily history on the Smart display. The card keeps readings at 4 second intervals and theoretically could store 10 years worth of data. Once transferred to your computer the only limits are practical ones! We have used this method as, at 4 second intervals, there is a huge amount of data - too much to transfer at the relatively slow speeds imposed by wires and would have required a much more powerful processor.
For those who do want live data on their computer, the USB cable provides this.

Hopefully the delay on releasing this product will only be short but we hit a problem when testing the new batch of displays and obviously need to find out what is going on.
The wait will be worth while!

Regards
Peter

Hi Peter_L,
how about putting a pair of volt free contacts inside so that when the generated power is greater than XX  we could use this signal to switch things on?
I have a GEO SOLO PV monitor that displays a tick when I am generating about 900watts, so the wife can get the Hoover or Iron going, but it would be usefull to be able to switch thing on automatically with it.
Other people seem to be devising circuits to do this, when there you are with the information at your fingertips,
just a thought Ken ;)

Hi,
Looking OK now, so we just need to build up some stock and it will be on sale.
Connected to a PC, demand can be exported to Pachube but I will be adding other "internet of things" sites soon. I also need to add the generate output, thanks for reminding me! We are also working on a Wi-fi module that will do the output and lots of other things without the need for a computer.

I have one PV system feeding into a sub consumer unit in the barn and another feeding into the main consumer unit in the house so I guess this system cannot be applied.
I have been using an Efergy unit to monitor the main supply to the house and found it very useful but you have to guess whether you're consuming or generating as it cannot detect direction.
Is there any similar unit available which can show which way the power is flowing?

Hi Don,
If the consumer unit in the barn has has power being used as well as generated you would need 2 SmartPVs; 1 in the barn and 1 on the main consumer unit. This will get you the generated and the demand but on 2 displays.  I will be looking at combining the information from multiple units in the computer program.
Hope that helps but more details will be available soon and you are always welcome to send me plans, photos of electrical installations etc. so that I can advise you in more detail.

I'm no power electrician but don't see how this would work.
The system in the barn would be OK as it would monitor the usage of the barn and the generation.
But the cable from the barn is connected into one of the ways of the main consumer unit so if I attached the clip on sensors to the house PV  neutral and the supply neutral,the supply neutral would include the current from the barn so the calculation be incorrect  ???

Hi Peter
I'm no power electrician but don't see how this would work.
The system in the barn would be OK as it would monitor the usage of the barn and the generation.
But the cable from the barn is connected into one of the ways of the main consumer unit so if I attached the clip on sensors to the house PV  neutral and the supply neutral,the supply neutral would include the current from the barn so the calculation be incorrect  ???
Don
Hi Don,
The barn supply going into the main consumer unit is a problem, and I am not sure about the solution. Your configuration is not that unusual and, although it will not work with the initial SmartPV we are looking at some alternative ways of acquiring the data.

Peter

Sorry, no idea on price yet but we will be competitive and there are some quite clever parts to the design. Regards Peter
You're probably not looking for any more ideas, but any chance that one of the 'clever parts' would be something like allowing a combination of data from a clamp sensor (for small, continuous data) and an optical meter sensor (for long term accuracy) as opposed to the one-or-other-only standard approach?  ;D

Thanks for the suggestion Much, keep them coming!
It is possible, we have a prototype pulse counter but I am already playing with a version of Trax that allows you to enter meter readings, Because we keep the data at 4 second intervals I am looking at using the meter readings to get the data to match the actual figures. Trials show that SmartPV with its voltage sensor is very accurate anyway but the meter readings would allow us to work out a voltage calibration figure for the installation.

One thing if you are building a pulse meter that supports LED indicators it maybe worth being able to record the length of time that the LED is on. When my meter sees power being exported the LED stays on until I am again drawing power. Combining this information with a current meter would allow correctly reporting of imported/exported power.

Both my main meter and generation meter are newish Landis & Gyr digital types which have the two optical holes (one flashing). I get the impression that the DLMS is standard on most newish meters, so if you're tracking meter readings, how about going the full hog and automating it?

Not to say anything about the accuracy of your clamps, but surely regional, time of day (and house) variations in voltage will impact the accuracy without extensive calibration? especially if there's a 'lil powerstation upstairs!

Great product especially if it is going to be able to control appliances. Unfortunately won't work for me my PV wiring is so neat there's no way to easily get at a single neutral wire for the PV clamp. Need a pulse counting divide to fit over Generation meter LED.


Title: Re: Eco Eye PV Smart
Post by: RIT on February 25, 2012, 03:29:02 PM
Thanks for the diagram, but for my home I do not have a central point that would allow all the wired sensors to be installed, without a lot of part-p rewiring. What I would need is your core device monitoring the main power cable and the leds on the electricity meter. From this it would be able to correctly report/log the current import/export current for the house as the led on the meter would be able to provide the direction of power.

While what you plan to bring to market does not meet my needs it is nice to see something that is more of a platform rather than the current black box solutions, I hope you are able to expand your range in the future.

Thanks

That's a crucial question !

Cos I already have a solar-switch  control on my immersion heater, (home-made) with tiny solar panel -> vol.control ->sensitive relay -> mains relay -> 110 volts for immersion heater thereby using  750 watts.

It works fine; except it is on-off,  which still wastes a load of sunshine :)

Post by: Automan on February 28, 2012, 10:42:34 PM
If the appliance monitors also monitor the load I would suggest a version without the ability to turn on/off the load so they can be used on appliances that don't like power cuts e.g. the fridge.

I notice the pdf instruction leaflet talks about the neutral and live. should it not be neutral and line?

I was more concerned about avoiding a proprietary protocol.
I'm presuming that (for the plug'n'play crowd) they'll be wireless / rf based (I only know of z-wave / zigbee in this area, although I guess bluetooth isn't the expensive high-end it once was); although I have a personal preference for hard-wired if I could ask for a simple socket to be provided..?
Regarding protocols; I've no preference, presuming that worst case one can be converted to another if a documented standard.
Will the appliance modules operate with a simple on / off relay or a more sophisticated variable output (dimmer swich analogy) ?
Another option could be to permit a large number of addressable devices; then have the module you want to output several levels use multiples of these (one per level) - not totally variable, but simpler


Title: Re: Eco Eye PV Smart
Post by: Peter_L on March 01, 2012, 08:45:57 AM
Hi All,
Thanks for the input - I am listening!
The protocols and controller are still to be decided.
They will be wireless but not Bluetooth (range is too short)
At the moment the modules are just on/off.
The modules monitor voltage and current and send that back to the controller.
The system will be capable of supporting many modules.
The modules can be set as not switchable for things like fridges.
The controller will attempt to make the most use of available power so a range of different switchable devices will give the best results.

More as and when.

Regards
Peter

One headache I hope you can spend some time on is that of security for the comms. Currently all the wireless devices I have around the house to turn things on/off or monitor have little no security. This works if you are not that worried about other people trying to access your stuff and the chance of other people nearby not installing the same kit, but is not a good long term answer.

If all of your modules are expecting to be mains powered the ultimate answer could be full 802.11b WiFi with each device becoming a full TCP/IP node. The one complication with this could be the cost - at least for end users such addons for Arduino development are costly.

The other option and maybe the best for what you are looking to do is to select your controller based on a vender that gives you best support for the ZigBee interface/protocol. The only problem is that while there are a number of already defined application specifications they can be just that - specifications but no code stack.

Hi Peter

Your new product looks very interesting, will it be able to upload to PVOutput.org as this site has large UK and worldwide usage already and has very good graphing and comparison tools. It would be particularly useful if you had a unit that could pick up the signals directly from the sensors and send them via a router to the net rather than having a USB cable from the Smart display to a 24/7 PC.
Here is my system for Generation and Consumption, with Outside temperature from my weather station on PVOutput.org; http://pvoutput.org/intraday.jsp?id=2476&sid=1872

Hi,
At the moment Trax just uploads to pachube.com but I will be adding pvoutput.org and thingspeak as alternatives.
We are also working on a wifi/network module that will avoid the need for a PC for the whole Smart range. This can be plugged into the transmitter or the Smart.

I think you may be being over-optimistic to expect bug free first deliveries.
Having been involved with putting a few things though from development into production, the delay and problems are almost always to do with assembly, delivery of materials at the right time and minor fit issues etc.

Designers will have done lots of testing against as many scenarios as they can think of but it is the first release to the customers who then try and do all sorts of unforeseen things with the product that inevitably throw up a raft of new issues

I hope I'm proved wrong.

Hi Ray,
Yes. I am working on adding Pvoutput.org to Trax and there will be an internet module soon that will do the job without needing your PC left on.
SmartPV display and transmitter can be upgraded by the user when new firmware is available and Trax upgrades are also easy to install. We really are keen to listen to what users want and provide extra functionality.

Im having trouble with Trax (the software) - it regularly fails to connect to the COM port, when it sometimes does connect, attempts to pull history/version etc cause it to hang.
Have tried different USB ports, different computers etc. Version 2.1g.

Any known/similar problems?

Different question - a couple of us cant use the full capabilities because our PV and Import feeds are in different physical locations, and the connectors wont reach etc.
Previously, I asked if there was a work around for this - I wonder, now having got hold of the device, would it be possible to have a second transmitter - would the receive take feeds from both - one having the PV, the second the Mains?

Hi Andy
Can you call me in the office 01903 851910 for help on Trax.

SmartPV is initially for the simpler PV installs  but it is always worth contacting me for other types such as the ones you mention.
There will be a number of enhancements coming over the next few months which might help.

I just copied the (ctrl-a) the contents of the SD card to my computer and ran the trax install and ticked "yes" to install the driver and got the attached pop-up.

I just copied the (ctrl-a) the contents of the SD card to my computer and ran the trax install and ticked "yes" to install the driver and got the attached pop-up.

(http://s15.postimage.org/hjb14urfr/No_USBDriver_File.jpg) (http://postimage.org/image/hjb14urfr/)

I found the installer, ran it and installed OK. Tomorrow I will be setting it all up. Hopefully it will go OK.

Hi Ray,
Looks like you are on Windows 7 - so this is not needed as Win 7 will load the driver automatically the first time you plug the cable in.
I will have to check the install instructions as I thought that was covered.

I see the problem with the driver; it has gone into documents folder and the documents are in the programs folder - Sorry!
I will correct that and post a set of updated instructions

Regards
Peter

Seeing the later posts I see it uses the Prolific USB drivers.

Do the PC's have an alternate version of Prolific Drivers installed?

I have two products that use these, an energy monitor and a GPS device.

For them both to work I have to use the Windows 7 drivers that came with the energy monitor and skip the drivers option when I install the GPS logger software (Holux).

Automan.

Peter/anyone with unit:

My PV Smart arrived today - thanks for the really quick posting.

Im having trouble with Trax (the software) - it regularly fails to connect to the COM port, when it sometimes does connect, attempts to pull history/version etc cause it to hang.
Have tried different USB ports, different computers etc. Version 2.1g.

Any known/similar problems?

Different question - a couple of us cant use the full capabilities because our PV and Import feeds are in different physical locations, and the connectors wont reach etc.
Previously, I asked if there was a work around for this - I wonder, now having got hold of the device, would it be possible to have a second transmitter - would the receive take feeds from both - one having the PV, the second the Mains?

Hi Andy,
Smart will work with any recent Prolific driver and with windows 7 you should have the latest one anyway.
The install option is there because it is difficult for anyone's installer to know if the driver is already loaded. So the best thing is to try the cable out and see what happens.
Windows sees each usb port as a different device and sometimes needs to load the driver if you move the device to another port.
I have a Holux gps tracker and will test it tonight.
Hope that helps

Hi all,

This is my first post on these forums and I'm excited to say I've just ordered the Eco-Eye SmartPV.

After looking at the usual suspects - Wattson Solar Plus, Current Cost EnviR, Owl+USB, Efergy e2 - I decided on the Eco-Eye SmartPV.

I hope I will not be disappointed!

Had my smart PV for a few days now and it seems very accurate when compared to what the current inverter output is, it gives the net feed to the grid, PV output and mains usage of the house on a simple display.

It does not seem to show net kilowatt usage on a daily basis (or if it does I have not worked it out yet).

I have a problem with the Trax driver but I think Peter L said there were some updates due, all in all I am happy to be able to see at a glance what is happening.

Hi,

Got my Eco-Eye SmartPV yesterday. Will post some unboxing pictures when I get a chance.

Had a quick go at setting it up and first issue I came across is that the sensor cables are quite short for my setup. They are 30cm/12inches long (or there abouts - I haven't measure it) They just about reach the transmitter box when all connected up, but the transmitter box hangs in the air unless I put a shoe box under it. I'll have it wall mounted when I have every set up and working properly.

There is a 3m extension cable you can purchase if you do have this problem:

http://www.eco-eye.com/products-cableextension.html

The other problem I have with my setup is that the AC cabling from my inverter do not have separate live,neutral and earth cables. What I had to do was open up my inverter front panel to get access to the separate wires. There is blanking hole in my inverter so I used that to feed the PV sensor cable through it and put the front panel back on the inverter. This workaround is the why I'm finding the sensor cables too short for my setup.

The next problem I had was that I connected the PV sensor cable to the live and not the neutral cable - Dho! So had to open up the inverter again to correct the issue. You also need to make sure the Grid and PV sensor cables are connected the the correct way around, the arrow should point in the direction (cabling-wise) to the grid meter and inverter respectively.

The transmitter unit uses normal AA batteries and the display unit uses two big/fat 'C' batteries (which actually forms part of the feet/stand for it). The batteries are alkaline ones and not rechargeable.

The transmitter and display units also have power adapter sockets. Suitable power supplies can be ordered:

http://www.eco-eye.com/products-poweradaptor.html

I haven't tried - but I would like to be able to put in rechargeable batteries and have them charged when using the power sockets. However, I suspect that this is not possible with the current design. Taking it a step further I would have like to be able to connect some form small solar charging system (at least to the display unit) to keep the batteries charged.

I had a bit of time to install the Trax software - came across the driver install error message issue mentioned above (I'm using Windows 7 64-bit) - but was still able to connect to the display unit as the the prolific drivers seems to have been installed on my system (I have used prolific USB serial adapters on my system already). Didn't get much time to play around - got email alerting working, was able to read the media card, but could not get Pachube (or Cosm as it is now called) working - probably because I'm new to it.

Regarding the media card. The instructions states that this is a special/modified MMC card and no other (normal) MMC card can be used. I would have like to be able to use an Eye-Fi SD card (although, instructions says it only supports MMC) and be able to sync/transfer the data over the wireless network. This would probably consume more power but if you have it connected a power source then it should not be an issue.

The controller display also does not have a backlight - but this is probably to reduce/minimise power usage.

That's all for now - I'll need a good couple of days to play around with the actual monitoring and data logging features and see how good it is.

Cheers,

SolarMon

Hi
Daily usage can be accessed by using the arrow buttons. Left once gets you to current day, press again for yesterday etc. Use the red button to changed between generate, demand and net.

Update to Trax very soon - thanks to RayG for his detailed testing!
There will be firmware update for the display as well that will allow the unit to show the received signal strength. This will help in setting the system up.
More soon

Had mine running for about a week now, installation was relatively straight forward but I had to do a little rewiring as my OWL monitors were on the live wire and the Eco Eye uses the neutral ones.

Overall quite impressed, compared with my two OWL meters it updates faster and does seem to be more accurate. I monitored it against the OWL and output displayed on my inverter and definately more accurate.

My only moan is that it only displays one set of numbers and you need to toggle between house load, PV output and net use. It would me nice to have one main number display and a couple of smaller auxillery ones.

Hi,
Thanks for your comments. We have always gone for a single large number for our displays as we find ones with lots of information confusing. Sorry!  Don't forget that the leds give you a quick indication of the net status so you can leave the display on demand or generate. We can also supply additional displays that can be configured for different displays.

Hi Peter_L,

You mentioned previously about a Linux version? When will this be available?

I would like to at least be able to get data to a Linux device so that it can be logged - is this already possible using the USB serial cable and a way to read the serial port?

I am thinking of setting up a low power ALIX device (http://pcengines.ch/alix.htm) and using that to log the data. The ALIX device can also be installed with Windows XP but I would prefer to use just a bare bones Linux OS.

Alternative to the ALIX devices, there are many 'plug computer' devices that should be adequate for a data logging setup.

Hi,
We should have a Linux version at the same time as Mac as they are very similar operating systems. As soon as the data format is finalized, that will be available too for developers to do their own thing. We are working on a network box that will give facilities for logging and upload to various internet of things sites. This is a top priority development now that SmartPV is up and running.
Hope that helps

Hi all,

I've been working on a web based monitoring page for my Eco-Eye SmartPV - please see it at:

http://www.one-n.co.uk/solarmon/

This is currently very basic and only gives the current values and simple sparkline graphs.

My SmartPV has been connected to a Linux server via its serial/USB cable where there is a PHP script that monitors the values sent down the serial port and saves the last few (currently last 15) entries to a data file. In turn, the web page (also in PHP) processes this data file and displays it accordingly.

The web page refreshes every four seconds - so you have a basic live view of the demand and generation values (in amps and watts).

Cheers,

SolarMon

Hi,
Sorry to hear that you are having problems, could you email the details to peter@eco-eye.com and I will get you up and running properly.
We are improving the voltage sensor and should have some more robust ones in in the next couple of weeks.

At the moment the Aux. input is not implemented as we want to make sure that the basics work first. There will be a firmware upgrade when we decide the best use for it.

Best regards

EcoEye Smart PV is the most accurate device I have tested. NO OTHER CT BASED DEVICE has so far been able to accurately measure the chopped AC your i2 produces. Only slow reacting optical sensor based devices could cope your none sine wave AC output.  This excellent and accurate piece of kit has enormous potential too!

Thanks Peter for bringing EcoEye Smart PV to market!

I have the same requirement as Echase. Before EcoEye Smart PV I:

1) Monitored Import/Export via an optical sensor based device - slow and can't differentiate between import/export!
2) Monitored PV production via the same device as 1)

1) + 2) have now been replaced by EcoEye PV smart - fantastic!

3) Since I have no meter in the Immersion circuit, I'm using a CT device which is quite fast but I'm not sure about the accuracy. I hope that the Aux input is coming soon!

Hi,
Down at the bottom of http://eco-eye.com/ecoeye-microgeneration.html (http://eco-eye.com/ecoeye-microgeneration.html) there are some pdfs including the instructions that include detailed Screen layouts.

I have just looked at pvbeancounter and it looks possible - live update to pvoutput.org will be in Trax in a couple of weeks together with full upload to cosm(pachube). I am also looking at including automatic upload of batches of data whenever the latest readings are transferred  to your computer. Another possibility is using the export facility in Trax to prepare files for other analysis packages.
We are also working on an internet connect box that will remove the need for a computer to be on all the time for live upload.

Hope that helps

Hello Franz

Is yours the PV model of Eco-eye or previous one?

Compared with cheaper meters it is much more accurate with the i2 (also called Intelligent Immersion and Solar24) chopped output. Against my 2 CT Locus LGate monitoring, which is probably within 3% of correct, it is agreeing within 5% based on the Trax accumulated kWh results. So I do accept that the Eco-eye is pretty accurate.

I don't though agree that all other CT based meters are inaccurate as the LGate is good and there is a revenue grade version still using CTs for more money that is probably within 0.1%. The clue to accuracy is not the CT versus something else but the way the electronics sample and process the CT measurements. Cheaper meters like the OWL don’t do it correctly. Some just measure the peak of the waveform and work out the power from that, but it’s hopelessly inaccurate for a non sinusoidal waveform and even a lot of modern electronic equipment like TVs and PCs are far from sinusoidal.

Peter thinks my unit is faulty though and asks me to return it. But it has not frozen up again for a few days and does now seem to be giving good results. But only have 2 full days of good data so far.

Bit puzzled about the CT and display labelling. The grid CT goes into a socket marked with a house symbol. But the house symbol on the display does not display the results from this CT. As far as I can tell it is instead displaying the difference between the 2 CTs.  To get the reading for the “house” CT you set the display so both PV and house symbols appear. Is that right Peter? Think it would be less confusing to label the Tx socket "grid" rather than "house".

Where I do question the accuracy of the Eco-eye is in its instantaneous power reading. Regularly today the LCD said I was generating over 3.8kW. My panels are almost certainly incapable of generating that much and the LGate says 3.6kW so what I surmise is that the sampling window is so short that noise spikes or waveform distortion can cause a few hundred watts to be added or subtracted from the reading. It does seem to oscillate about a lot from reading to reading. It’s perhaps a correct reading but misleading, so would it not be better to lengthen the sampling window so the instantaneous reading smooths out these spikes? The spikes were not coming from my i2 as I turned it off to check and it made no difference.

Is the instantaneous reading the average power over the 3-4 sec period between display updates or the instantaneous power at the point of transmission? On the LGate it sends an instantaneous reading but also the kWh accumulated between samples which is effectively a smoothed power reading.

What you could do is loop the immersion live or neutral wire through the “house” CT so it has 2 wires through it. If in the right direction it will subtract the immersion current off the grid current so that CT will measure only what the house consumes, ignoring the immersion current. Then the bargraph display will correctly show one’s consumption.

Downside is loosing the export reading showing how brilliant the i2 is at limiting export to say around 50-200W.

I have not tried this yet.

Tripped myself up with the labeling problem mentioned in post #134. I think this should have read:

"so the house symbol on LCD will display only what the house consumes, ignoring the immersion current."

I did a quick comparison of my Sunny Boy inverter's display against the Eco-eye just now. It updates every 5 or so seconds and shows a slow change of up to 1 % between readings, with very dull weather (so panel output is changing little between samples). The Eco-eye though can vary 5% between PV readings which I doubt represents reality. Reinforces my view that greater smoothing between readings would be ideal.

What you could do is loop the immersion live or neutral wire through the “house” CT so it has 2 wires through it. If in the right direction it will subtract the immersion current off the grid current so that CT will measure only what the house consumes, ignoring the immersion current.

In theory the correct orientation is for the immersion supply live wire to be inserted together with the grid live wire such that it enters from the house side of the CT and exits on the gird side on its way to the immersion.

What this CT is measuring may depart even more from a sine wave with this wiring, so need to check that Eco-eye is still correctly reading the true RMS power.

My take on the drive for accuracy is that it is more important to ensure that the Eco-eye power calculation mirrors that done by the board meter on which you are charged.
Not much seems to be known about how this integrates and averages and with what time constants - certainly by me and reading elsewhere, others are equally unsure

By “board meter” do you mean the PV meter or the normal house meter? If PV one then adjusting the voltage reading in the Eco-eye should obtain a match with some experimentation.

If you mean house meter then you have a problem: on the PV version of Eco-eye, as it discriminates the import from export, the total kWh it records will be total import minus total export. Whereas the board meter will only be total import (assuming the anti-reverse facility works). So you can never get them to match. Don’t think the previous Eco-eyes (or any other non directional make) will match either because they register the total kWh as total import PLUS total export.

Title: Re: Eco Eye PV Smart
Post by: ms15342 on August 01, 2012, 09:15:42 AM
I am still happy with mine, it gives a figure showing what we are sending to the grid during the day and I can turn on immersion or other devices to utilise that power, though of course you need to be at home to do this.

In a two people household we averaged 3300 kilowatts useage per annum before the panels were installed last October, and we now appear to have reduced that to circa 1500 kilowatts (daily readings from meter) not Eco eye.

I have not been able to use the Trax element and am awaiting an update from Peter when it becomes available.


Title: Re: Eco Eye PV Smart
Post by: echase on August 01, 2012, 10:16:20 AM
After the initial problems reported above I did not return it for replacement but left it to settle down. Peter suggested I upgrade the Trax software and the supply unit firmware. These caused slight changes in functionality but I don’t think it had any relevance to the past problems.

I have done some quick crosschecking against my 2 other ways of measuring the data and the Eco Eye appears quite accurate.  So in the medium and long term it is probably adequately accurate for a unit of this price, but I still think the reading to reading variability is too great.

I’ll repeat my previous question as no answer came, “Is the instantaneous reading the average power over the 3-4 sec period between display updates or the instantaneous power at the point of transmission? On the LGate it sends an instantaneous reading but also the kWh accumulated between samples which is effectively a smoothed power reading.

The point of the question is that to make a measurement any device has to average the power over a small time window, which at minimum can be one mains cycle long. The more cycles are used the more likely short term spikes and timing jitter are smoothed out. Failure to start/stop the sample window at the beginning and end of a cycle will cause variability too so you should not just start and stop the sampling at exactly 4 seconds but adjust it to the nearest zero crossing.
 
Every 5 minutes the LGate send an instantaneous power reading, probably sampled over a few cycles, and then also adds up all the cycles in the 5 minutes and sends that data too as a kWh reading. But you can derive the average power over the 5 min period from the kWh figure by multiplying it by 60/5.

One new problem I found is that when you compare the downloaded csv data off Trax the coarse and fine granularity data are time shifted by 24 hours. Peter is looking into it.

Obvious question;
Is the communication / control with appliance modules any type of standard? ie. using a protocol common to a home automation system? Would do wonders for integration! :-)

Hi
We have the appliance modules prototyped and working but the actual operation and integration is still to be developed. I am probably going to wish I had not said this but, any suggestions?
Regards
Peter

Hi Peter,

A few months later I wonder whether there's any news on the appliance module?

Are you still at the "looking for ideas" stage, or have you got beyond that?

I guess at the simplest case I'd be looking for a plug-in mains switch (similar to the X10 stuff) that listens to the PV Smart signal and essentially switches on and off pretty much in time with the LED traffic lights on the main unit going red and green. Perhaps with a small hysteresis delay to stop the device rapidly 'flapping' when at or near the switching point.

Even better would be if, rather than the switch point being the import/export cutoff, it could be notched up to, say, 1kw or 2kw export. Maybe 500w increments between zero and 4kw? I guess that would suit most applications. Anything with a bigger load than that wouldn't be plugged into a 13A socket!

P.

Hi All,
Sorry I have been relying on notify to let me know if there are new posts on this topic and they do not seem to be working so I have missed a lot of what is going on.
I will catch up today and try and answer all you queries.
Quick updates
If you are not already on Trax 2.1m it can be downloaded from: https://www.box.com/s/psnhzilgsxnp8piztrxa (https://www.box.com/s/psnhzilgsxnp8piztrxa)

The main appliance modules will not be ready for sale until the end of the year but we are working on a smart immersion switch which could be out much sooner.

More later today

Regards
Peter

Another 'nice to have' would be a simpler box with just the data output.

Logic is as follows: Main display in the kitchen, so that we know when it's safe to use the washing machine, etc. But I don't want a server in the kitchen! Server is in the office upstairs, but if I put the main unit there we have to keep going up each time we want to see the traffic lights.

So a cut-down receiver with just the output, no display, no buttons, would be great!

In the meantime, can I buy another display box to use upstairs? I notice you list this : http://www.eco-eye.com/products-solo-smart.html but it doesn't mention whether it's compatible with the PV model.

Peter,

What version of the Prolific chipset do you use in your serial lead? Only I'm struggling to get it working in Windows 8 (but that could be because it's in a VM).

I notice that Prolific says:

  - Windows 8 is NOT supported in HXA/XA chip versions (will show yellow mark Error Code 10).
  - Windows 8 is supported only in following chip versions:
      - PL2303HXD (HX Rev D)
      - PL2303EA (ESD protection)
      - PL2303RA (Built-in transceiver)
      - PL2303SA (SOP8 package)
      - PL2303TA (PL2303HXA/XA replacement)
      - PL2303TB (12 GPIO)
 
I'm seeing the yellow error 10.

Thanks,

P.

Hi Paul,
Sorry for the delay in replying. I cannot get the details at the moment but Prolific are not supplying drivers for windows 8 for them.
We will look at changing to a different chip when we make the next batch.
I thought Windows 8 is not being released until October?

October will come round quicker than you think!

I've been running it a) to test it because it's bound to come up as part of my main business (I own a web agency), and b) because it's important to know about compatibility with phones/tablets for my other job (Real World Mobile & Wireless columnist for a tech magazine).

Even people that buy a PV Smart now may well look at upgrading to Win8 at some point in the future, so it would be good if the leads with alternative chips were available separately. Although having said that, I'm more interested in the Mac and Linux versions, as I use a rMBP as my main home machine, but ideally want to plumb a PV Smart receiver into my Linux based NAS to store data, draw graphs, etc.

Hi All,

Just wanted to jump in and say that I got an eco-eye bundle a couple of weeks ago, and it's all working very nicely.

Peter sorted me an extra serial cable (non usb) so it was a piece of cake to connect it's output to a simple microcontroller, sniffing the data and pinging a relay to dump excess power via a 1KW immersion.

I'm looking forward to seeing the product develop and expand :)

Cheers

Hi,
Sorry for the delay in replying.

I have got most of a linux version working but I have been waiting until I have a stable version to finalize it and then check it on various flavours of linux.
If you want to run Trax on your Pi you will need it set up as a desktop and you will need a GUI that supports QT.

I will try and get something out soon.

Hi there,

I'm interested in purchasing this. 

My inverter is located in the upstairs loft.. and the meter reading and consumer box located in the ground floor.  The Grid reader outside of the property.

Based on the instructions

http://www.eco-eye.com/downloads/PV-Leaflet297x210.pdf

there are 3 sensors which needs to connect to any voltage, inverter and grid.

Assumption is that it has to be connected to all 3 within the same vicinity?


Thanks!


Title: Re: Eco Eye PV Smart
Post by: Peter_L on November 07, 2012, 02:19:17 PM
Hi,
The three sensors do need to be connected close to each other so, as long as you can get at the tails from your grid meter where they enter the consumer unit you should be OK. If you want to be sure you can always email a picture to info@eco-eye.com and we will check it for you.
Best regards
Peter

Currently you have to connect your SmartPV to a computer or something that can connect to the internet, could be a PC or laptop, or like me a NAS (network attached storage device).  I was originally thinking of getting it set up with a Raspberry Pi.

If its a windows machine you can just leave it on and turn on Trax, you need to sign up for Cosm www.cosm.com and then put the required details into trax, it will then upload the data for you.  I then signed up to pvoutput and it can take the data from cosm.

pvoutput also have a android app so I can keep an eye on the usage and generation on the go.

Good luck.

Hi Everyone and sorry for my absence!
There are a lot of things going on at the moment and there will be details soon.
In the meantime, one of our users has written a raspberry pi interface for the standard Smart that could easily be amended to suit PV
This is available from https://github.com/glennpierce/horus (https://github.com/glennpierce/horus)

I am also setting up a google+ community for Eco-eye users and developers. The basics are at https://plus.google.com/communities/101361898501376859422 (https://plus.google.com/communities/101361898501376859422). I am still trying to understand how it works!

Hi All, I have a 4Kw solar array and immersun unit, is there anything out there that I can monitor inport/outport from a remote unit in my kitchen?
 
I used to have just a basic unit that would tell me if I was overproducing or importing and by how much, but now with the immersun (which I'm very impressed with) it is not so easy to tell, OK I can go out in the garage and have a look at immersun to see if it is redirecting and by how much before turning on washing machine for example, but it is not very convenient!!

How are other immersun users monitoring theirs?

Regards, Jeff.


Title: Re: Eco Eye PV Smart
Post by: echase on April 18, 2013, 09:20:33 AM
I use an Eco Eye Smart PV to monitor export on my Intelligent Immersion I2 device which works in a similar way to the Immersun, but without using burst firing. On my unit the sample to sample reading on the Eco Eye oscillates so one reading might say 126W import and next 4 secs later says 105W export. Short term averaged they are probably correct and the values plotted on a PC seem right. So it is giving an indication that is better than any other meter in this price range but you can't look at it and say "Ah it's steady at 56W export".

Not clear why the ECO Eye does this. It's not the Intelligent Immersion fluctuating as much more expensive and accurate monitoring systems than the ECO Eye have proved.

Can't tell you if the Immersun would show the same behaviour but, as it’s a burst fire unit, the number of full load mains cycles in a 4 sec period is unlikely to be consistent (don't need to be consistent to control properly) so I'd expect reading variability.

Hi,
Make sure you are on the latest version of Trax - currently 2.1z http://eco-eye.com/traxdownloads/ (http://eco-eye.com/traxdownloads/)
Set up your user in Cosm
Do not set up data feed in cosm
In Trax, enter your user name and API (make sure it has full access)
Enter a name for your feed and click "create new feed"
If all is well, there should be a message and the URL for this feed will be at the bottom of the window.
tick "start automatically"
OK
On the real time window go to File and make sure that Cosm is ticked.

If it still is not working call me at the office.
Good luck
Peter

I'm using the Smart PV through COSM to push on to PV Output via a low power PC I have spare.  I have a secondary Smart PV permanantly hooked to the PC via USB.
 
http://www.pvoutput.org/list.jsp?id=18812&sid=16664
 
Works very well although I needed to enter a formula into the feed setup in PVO to convert the COSM feed (kWh) to show correctly otherwise PV Output thinks its watts and you get next to nothing showing.
 
The formula is power *= 1000; which you need on both the generation and consumption figures that COSM gives.  After that you're good to go.
 
Only slight problem is when you have an Immersun or similar as I do.  The Smart PV takes the surplus sent through it as draw on grid so your consumption figure can be artififcially high on PVO.  That said it allows me to see exactly when the Immersun is working so as I don't really track consumption through this I see that as a bonus "feature"

Think you have hit the nail on the head there. So many people have monitoring or control systems that consume loads of electricity and make a mockery of trying to save the planet with a low energy control device. E.g. I have one that, whilst it is fairly power efficient, uses Powerline adapters to pass the data to the internet router and these consume tens of pounds of electricity pa. Even the Pi is quite power hungry at 7W or so, not including any screen.

Our Intelligent Immersion i2 solar diverter only consumes 0.5W when quiescent but it does not have an internet connection yet. The Smart PV is a good low energy way to monitor it but I use the other monitor for long term plotting.

A standalone web box to PVOUTPUT would be great. I have the exact same setup and have tried to optimise as much as I can. I run an old laptop with the screen powered off and the Smart PV connected. The same laptop serves as a DNLA media server / backup server / weather station server (Cumulus) so it's multi tasking. It's a very stable setup.

I've had some trouble with the accuracy of my uploads to PVOUTPUT so now use this forumula

power *= 1.55; power *= 1000

Gets me to about 98% - 101% accuracy when compared to my Sunny Beam (which reads direct from the inverter). The Smart PV on it's own reads to about 96% accuracy I've found (again when compared with the SB / Gen Meter)

Following you now bellPV, always good to follow people with a similar setup

Hi, did you mean 1.55 in your formula?  That would add 55% to your readings so seems a massive adjustment.

I'm using the following now as the smart PV gives some spurious data through the night and like you it needs a small adjustment to make it in line with the inverter readings.

if(power * 1000 < 50) power = 0; else if(power * 1000 >  49) power *= 1.05; power *= 1000;

I've had a few days where its reported one off generations over 5000w which isn't possible so may adjust the above to return 4000 if that happens again.

Cheers

Hi Bluebell,

I actually use 1.54 and I agree it's a massive adjustment.

I am not sure why the native data sent across from cosm is so far out, but in terms of generation I need to do it and it does bring me in to that 98% to 101%.

In terms of consumption I haven't cross checked the accuracy but I imagine it will be a bit off as well. Maybe about 95%.

I have setup Trax to send me the daily e-mail reports and I often find generation figures to be anything up to 1Kwh less than the reading from the inverter (and Sunnyboy).

I like your equation but I if I use it I will seriously under report both generation and consumption.

Is there a setting I've missed somewhere?

Hi Kanu, Not sure there are any settings you can use in COSM to affect the feeds.  From what I can see it's pretty much an input output processor.  I do use the debug mode in COSM though so you can see exactly what numbers are being pushed up from the invertor and that may help you narrow down the point where the numbers may be affected.  It's certainly where I spotted the need to multiply the input numbers by 1000.

The formula I only apply to the generation input from COSM as PVO let's you individualise the formulas per stream so it just clears out spurious feeds that comes through some times.  Consumption is accurate enough for me and as I have an ImmerSUN the consumption is artificially high because it shows the diverted generation as consumption.  I like this though as it lets me see when the Immersun is running and I'm more interested in the generation anyway.

Checked the figures the last three days now and PVO and the inverter have been within 100w of each other on 20-27kw generation numbers so confident the numbers are good.

Cheers

Struggling with Trax. Can’t seem to get it to move forwards through the dates using the calendar/date menu in middle top of its window.

My dataset starts on 15/12/12 and Trax starts up showing that date. The calendar feature enables me to move the data earlier, where there is no data to display, but refuses to shift the date any later than 15/12/12. I can use the arrows at bottom right to shift it but, if say want to see the day or hour view, it is mightily tedious moving from 15/12/12 to today. What is wrong? This is with the current 2.2a version but 2.1 was the same.

The calendar feature enables me to move the data earlier, where there is no data to display, but refuses to shift the date any later than 15/12/12. I can use the arrows at bottom right to shift it but, if say want to see the day or hour view, it is mightily tedious moving from 15/12/12 to today. What is wrong? This is with the current 2.2a version but 2.1 was the same.


Hi,
Sounds like something may be wrong with your data. Can you send me a copy of the files and I will have a look.

Peter

Hi All,
SmartPV does seem to be reporting PV on the low side and we are investigating.
You can increase the kW by increasing the voltage on the settings window. This works particularly well for the email reports.
Make sure that you are on the latest version of Trax, there were some bugs in the Cosm output that were fixed in 2.1y. Latest version is always now at http://eco-eye.com/traxdownloads/ (http://eco-eye.com/traxdownloads/)

Best regards
Peter

There are 3 files, all in c:\Eco-eye\files\ the name of your datastore.

Looks like COSM is no more....    wackoold

Has anyone seen any info on Xively and when PVO is getting updated to take the newly named URL feeds?

Assuming the change is needed in PVO as the only change I can see is this renaming on the feeds.

Shame as it was all working so well it now back to manual entry if I want to log stats from smart PV and that's a right ball ache!

Cheers

I had an interruption in service and my Eco Eye must not have liked the switch but it seems to be working now.

Can't see the need to move to the new API, will leave as is until it breaks!

Hi Peter,

what information does it upload to PV output?
Currently my system only uploads what I'm making.

Also will there be any additional upgrades to the unit coming out over a period off time?

One thing I would like to also monitor is the temperature of my hot water tank for use with my solarimmersun unit.

Thanks.

Hi,
Generate and demand are sent to PVOutput every 10 minutes. If you want to have a look at an example, my installation is called Sunny Horsham, system id 138208. the live graphs are particularly good.
There will be various upgrades coming out for SmartPV. Sorry, Tank temperature is not on the list at the moment.

Hi Peter,
Thanks for the direct PVO feed works great!!!!
 
The generation modifier also works particularly well and continues to let me hit 99.9% accuracy between PVO and My Inverter logged outputs. One small further addition for the next point release would make it perfect if you could consider it.
 
In PVO you can add formulas to normalise the feed inputs from COSM and you have already sorted a good chunk of this with the generation adjuster.  However one other quirk I get is that the Eco Eye gives a 5-15w readout through the night when obviously the system is shutdown.  In PVO I removed this by setting a formula to 0 anything less than 45 as I know my inverter starts up at 50w.  Could you consider adding a simple drop down to allow users to set a tolerance below which it reports 0w to the next release?
 
http://www.pvoutput.org/intraday.jsp?id=18812&sid=16664&dt=20130625 This shows my page today as an example of the feed figures through last night where you can see the spurious generation.
 
Many Thanks Andy

Hi,
Good to hear that PVOutput is working.
The little bit on the PV when it is dark is just the power being used by the inverter to keep itself alive. I am typically seeing 2 watts.
Good idea about a low end trim value, I will see what I can do.
Back on to Wifi next week. Boards are here and most of web side is done but I need to learn smartphone app programming.

My inverter starts at about 35w so is similar but when light levels drop it runs all the way down to 0. It has been below the 35 for a long time on a rainy day. Only a minor ammount of power but it is still producing.

Blimey, I turn my back for a bit and suddenly new features like PvOutput appear :)

Before I start dismantling my existing PvBeanCounter monitoring, just a couple of questions...

Am I right in thinking the Trax PvOutput is just from the Smart's live data feed, or is the historical data from the SD card also used?

Thanks

Hi Ian,
Yes, PVOutput is just from Smart live feed through a PC.
I am having a look at the possibility of a batch feed from the card data but although relatively straightforward, there are quit a few things to think about.
Just working on a simple live feed program for Linux etc. so Raspberry Pi for example come into play. I am hoping that this will also work om Macs. A version for Windows will allow it to be auto started on boot up.  Should be available in a couple of weeks.

Hi Peter,

You still have many plates to keep spinning then ;)

I'm sure there's a few people other people who turn off PCs overnight, my huddle of machines are all scheduled to run a BAT to  RoboCopy backups, then PSKILL them into hibernation.


For Windows,  an option inside Trax for a regular (daily?) batch upload from SD would mean that if a box/lan/interweb had been of for a while, then the missing data would be filled in.

Also, a command line parameter for Trax would be useful, to force a historic batch update, then exit the application.

Then it's a simple matter to run a scheduled task to just do a daily upload.

I have to say, the RaspPi idea is a good one for a cheap, low power 'always on' option :)

Thanks

Ian

Unfortunately the files exceed 45Mb so can not be emailed. The exact problem has changed from my post on May 7th. Now using the left arrow in month view scrolls back through the data to the 1980s and before which is clearly wrong. Any ideas?  In other views it correctly truncates before Dec 2012.

There are some gaps in the data of a few hours or days. Not sure why that is, but the short ones might be when I reset the unit and re-entered the date and time.

Hi,
To start measuring something new: make sure you have downloaded everything from the card, go back into card on Trax and initialise the card. When you have some readings from the new system, select new rather than update in Trax, give it a name and away you go.

Hi everybody
I stumbled across this forum whilst googling automating uploads to PVOutput, what a wealth of info there is here.
I've have had an 8KW solar array installed for about a month now and am loving it! Shame I missed the great summer we had but there's always next year  ;)

Anyway, I have a Smart PV which I have just hooked up to a nettop pc that is in turn uploading to PVOutput. I saw this thread and noticed that Peter L was working on a live feed program to run on Linux.
I have little to no knowledge of Linux but am extremely happy to start a steep learning curve and give it a go. I love the idea of using a Raspberry PI to upload data 24/7 due to its low power requirements and stability. Failing that a windows version that will run from boot up would be great.
Are there any updates on either of these two projects that Peter mentioned as this thread seems to have gone quiet for a while?

Hi,
There is a lot going on and I am not managing to finish any of it!
1. New version if Trax that will work on Mac OSX and has a year graph
2. Standalone program for handling real time upload to various internet sites. This will be available for all platforms and will be able to be started at boot-up without the manual intervention required with Trax.
3. Raspberry Pi card image with the program mentioned in 2 above using web configuration so that it will be easy for anyone to use without knowledge of the Pi. However it will be open so dabbling will be welcome!
4 Various new projects!

1, 2 and 3 are very close to completion so it is just a matter of getting them done. There will be a newsletter when they are ready.

Hope that helps

Hi ,
I do not get an update to Trax version 2.2c from the version 2.2b installed on my PC . Any suggestion ?

Has anyone studied the reading of Log files into Microsoft spreadsheets. I have found that a CSV saved (Hourly basis) only comes up with 23 hours in the day . I have read all the posts on this thread without finding a mention . Any comments ?

I have other issues still under investigation but my system has only been up 8 days so I need a bit longer to make a more meaningful post on these .

Any help ,specially on summated values would be appreciated .

I don't know whether this has been mentioned before but with my ecoeye uploading both used and generated power to pvoutput this recent iPhone App works great displaying both parts of data.

Hi

Is there an SDK (or at least a feed spec) available for PV Smart?

Just got one for Christmas and thinking about writing a batch upload for third party monitoring sites.

Hi
The feed is very simple and the details are near the bottom of the trax page on the eco-eye web sitehttp://eco-eye.com/trax.html (http://eco-eye.com/trax.html)
A lot more will be coming soon including raspberry pi example programs

Best regards

Any way to get historical data from the unit without unplugging the memory card?

Only gOt my unit yesterday and having run for ten or so minutes with like data from trax I enabled pvoutput feed. Within moments my unit lost wireless connection. I unplugged serial and went near meter and still nothing until I removed/replaced batteries. All ok until I connected serial cable again, moments later, wireless link died and unit needed battery removal.

Synopsis, running fine 24 hours then on two occasions moments after connecting to trax in pvoutput mode, display loses wireless connection and needed battery removed to recover. Seemed fine when trax not in pvoutput mode but need to confirm.

Something odd going on but further tests are not so conclusive.

Looks like I might be right on limit of reception and that plugging the serial lead in is enough to disrupt wireless signal.

I was able to partially recreate problem today and now think pvoutput is red herring. Certainly plugging in serial lead when in my office is enough to disrupt wireless link however, today I was able to reinstate the link most times without removal of batteries. In addition, I ran for many hours when connected to different PC in different room without wireless issues.

So I will monitor (pun intended) over next few days in different scenarios.

Hi,
Couple of things to check first. Make sure that the batteries are good and check the received radio strength.
Radio strength is round green button to time then red button. you should be getting a strength of better than -10.
Have you fitted the external antenna wire?
Howevery it sounds like you have a fault with the cable or the display and we would be happy to send you a replacement. Just email info@eco-eye.com with your details.

Hi,

Happy New Year!

I only found this forum by chance, looking to see if anyone had developed anything on the Raspberry Pi for the Eco-Eye Smart PV. I'm really pleased to have found like minded souls now!  :-) I've had an Eco-Eye Smart PV since June 2012 and in the past I have always contacted Peter via email, so I'm glad to have another channel open.

After Christmas I am now the proud owner of a Raspberry Pi. I have been thinking about what to do with it and using it to capture date from the Smart PV and send it to PVOutput seemed an obvious choice. I've been using PVOutput since Oct 2011 and have written a VB program to upload my SunnyExplorer/SMA SunnyBoy output to it (go to www.pvoutput.org and search for "JST200" and select  the "JST200, Live" system). It would be excellent to upload my Smart PV data to it too!

So please include me on any Raspberry Pi release as you mentioned in the post above, please, Peter! Although I've not coded with Python before (only Macro 11, Macro 32, Fortran and VB) I'm up for giving it a go. So would be pleased to look at attempting some development work.

Cheers, Jim

I've written a python script that I am currently testing on my new Pi. Will be happy to post on here in a few days time when its had a few more days running. Its currently just updating averaged house and gen power to pvoutput, but I am thinking of adding temp from local weather station. Having to wait for 5 minute status intervals and some brighter sky's is a bit of a pita when checking output.

@Peter_L: can I interrogate the PV Smart for things like voltage? I've hard coded 240v when converting from amps to watts but it would be nice to get this from the PV Smart itself.

Hi Ian,

I would definitely be interested  in your script, if that's OK. Anything to get me started!    :)

I guess you know that PVOutput will auto add the weather/temperature for you from a local station, using weatherunderground as the source?

However, I too (for my VB app) coded a feed from a local station (either using google or weatherunderground as my source), adding it to my upload data. I started coding it just before bankstownbloke added it to PVOutput, so kept going for programming practice.

I don't know if this will help or is wanted or not, but pvoutput only accepts a few weather type designations so those provided by google or weatherunderground need condensing. Here's my conversion table (VB coding structure removed):

Im using the live status update (at 5 minute intervals). This only provides temperature input and not conditions. The weather conditions are in the end of day add output service which I have not addressed yet but assuming that cumulative calculations can be relied on, probably would not take much to implement. Having only got Pi a week ago, I've used this as a crash course into Pi and Python so am happy to post the script for others to play with, may be even later today.

Im eventually going to interface with my inverter for the generation and voltage info which will be a better place to obtain the eod bits although depending on how my calculations add up over a few days I may see about adding the add output message. I only wrote my script this weekend so your post was very pertinent, but as a result, I don't have much real data to work on and only finished the upload to pvoutput yesterday evening (after the sun had gone down) and having found a bug in solar generation this morning I have scrapped data from earlier test runs.

As I'm averaging power over a 5 minute interval, I have yet to fully see how well this tracks over longer periods of time. I may need to use another algorithm to smooth peaks and then plot instantaneous readings on the 5 minute interval. So that may need to be changed if averaging doesn't track very well.

You can see my output here (http://pvoutput.org/intraday.jsp?id=28172&sid=25797)

Hi Ian,

Output looking good - look forward to seeing your code. I'm impressed you've only done it in a couple of days!

Something else about PVoutput that may be helpful to you. It allows you to have multiple systems defined, each identified by it's own code. So I set up a "Live" system and then a couple of dev systems,  so I can test changes against the dev systems without disrupting my Live data. Maybe not so helpful when using pi for real time data - but perhaps worth a thought?

I was wondering how you agragate the 4 sec updates into 5 min uploads.  Presumable sum the 5m of updates divided by 75 to get the average?

Cheers, Jim


Title: Re: Eco Eye PV Smart
Post by: JST200 on January 06, 2014, 12:07:18 PM
Oh, another thing which may be obvious but caught me out... what time of day to take your snapshot of the days conditions.

If you take it at the time you do your EOD processing, then that may well be sometime in the middle of the night - which may not be representative of the day.
So I decided to take my snapshot at  15:00 - being west facing the time most likely to produce the max PV output for me. Once you get your monitoring up an running you can cross check this time with reality.

With regard to smoothing. I find that PVOutputs own smoothing algorithms do a pretty good job with short update intervals (5 - 15mins). Beyond that they get a bit steppy I think.

Cheers, Jim


Title: Re: Eco Eye PV Smart
Post by: ianh64 on January 06, 2014, 03:55:24 PM
Im attaching my script here. Its basic but should provide equivalent functionality of that offered by Trax PVOutput upload.

Its a little in return for the advice and assistance provided by people on this forum. Even though its setup for the EcoEye PV Smart, there are a number of useful bits in the code that can still hopefully benefit those not using the EcoEye unit.

In spirit of Raspberry Pi, please feel free to experiment but please do keep to rules of GNU GPLv3 license if you decide to modify and pass on.

As far as testing after a couple of false starts, its been running most of today which is totally inadequate for production use however it seems to run reliably and produce results in the right ball park as expected. But only time will tell how well it compares to real figures. However, I have released into the wild in this state to get some early feedback.

If you get the program to auto start on Pi boot, please let me know. This would allow it to run headless with just the EcoEye USB/Serial converter plugged into the USB port and a network connector which is tbh, the final aim for me.

It requires Python3 which was on my version of Pi distributed by Maplin as the basic kit. To get it up and running, you will need to download the serial library - instruction on how to do so are in the script header. I have run it from both the IDLE3 environment and from a terminal (you need to set the script file to exec (chmod +x pvs2pvo.py) and run as ./pvs2pvo.py). Like skinning cats, there are other many alternative ways to get it up and running.

Im not convinced that the simple averaging works particularly well in the sort of weather that we have been having today - i.e. sun in/out/in/out shake it all about. I think a weighted moving average or kalman algorithm for filtering would provide a better instantaneous reading. Feel free to experiment and report back.

Currently, like Trax, it only implements the PV Output status message for intraday live readings but it would not take much to modify to add an output message for EOD. It could probably do with a bit of error handling included too, especially exception handling in the PV output connection handler.

And before you get it up and running, you will need to change a few variables at the start to suit your needs and PV Output settings.

I called mine, pvs2pvo.py when looking at the references above and below.

Script moved to Home Automation and Monitoring Section (http://www.navitron.org.uk/forum/index.php/topic,21807.0.html)

That's brilliant, Ian. Thanks.

Unfortunately, being new to Pi I'm falling at the first fence :(

I've done the "sudo apt-get install python3-serial" which seemed to run to completion OK.

However, when I run your code in IDLE 3 I get "ImportError: no module named serial" from the "Import" line of code, which I assume means it can't find the imported serial modules.

Any pointers very gratefully received!!

Cheers, Jim

Post by: ianh64 on January 06, 2014, 06:45:17 PM
Your assumption sounds correct. To resolve, try/check the following. Otherwise, its google Im afraid.

Did you definitely put the 3 on Python when you imported. Otherwise it will go to python 2.x.

Are you definitely running Python 3? On my Maplin version, it is IDLE3 icon not the IDLE icon.

Also, have you restarted Python after the install? Ie not been running python/idle in window shell whilst installing - don't know if that will make a difference.

Double check the install logs.

Also, have you updated your OS to latest version?

Of course, I may also have given wrong instructions to install serial! I've only done it once and had to search google for the instructions so I may have found wrong ones. wackoold


Title: Re: Eco Eye PV Smart
Post by: JST200 on January 06, 2014, 07:47:01 PM
I scanned google first and the answers seemed pretty much what you have suggested.

In answer...

I'm pretty sure I did.
Definitely running Python 3 (IDLE 3) (V3.2.3 to be exact), though I did try Py2 (IDLE)with the same outcome.
Tried the install command a couple of times and pretty sure Python wasn't running at the time.
Haven't looked at the install logs - something to find and read  :)
Latest OS installed I think (I used the NOOBS_v1_3_3.zip) which has a release date of 24/12/2013.

Well if it worked for you it ought to have worked for me!  lol

Thanks for the help - google here we come.   ;)


Edit/Update:  Found the  install log and guess what - you were right! Initially installed python-serial and not python3-serial. However, I did then install python3-serial but I have a feeling the first install would have mucked it all up. So next lesson, how to uninstall an install and try again!

There seem to be a variety of ways of installing pyserial. The pyserial documentation only briefly hints at the method that I used. I think I found the method that I used specifically for Raspberry Pi.

I don't know if it is possible to look in the python 3 folder for the serial module.

I just searched in google for the bits missing from my knowledge, which is a lot as its 30 years since I last used unix in anger although amazing how muscle memory can still persist after all these years and the fingers still just type some relevant commands.

Give

And
http://www.raspberrypi.org/phpBB3/viewtopic.php?f=32&t=51468
a try for more info/hints.

Not sure if a mod would like to move this latest discussion to a more relevent forum - I noticed one called Home Automation and Monitoring which may be a better fit for home brew code.

Hi Ian,

Thanks for the pointers. I checked out those, plus quite a lot of other sites too and the general consensus seemed to be to download pyserial.zip and install it manually. Which I did.  Still no joy. Same error.   ::)

So before I re-installed the whole system from scratch (to give me a clean slate to work from) I thought I would create a new .py file adding your code one small section at a time. I only added a library element to the import statement as it was required by the added code. After each code add I ran it to ensure it ran OK.

The only issue I found was that I needed to comment out the "com.open()" statement, otherwise I got an "serialexception: com port already open". Reading up on the error it appears the "com.serial.Serial" statement issues an open anyway (but I wouldn't swear to that!).

After adding the final "print("Processing PV Smart..." section of code, it miraculously burst into life!!!

As far as I can see there is no difference between the original code file and the built up one. Whenever I try the original code file it always displays the "serial" error - even if I completely remove the import statement. Weird!   banghead:
I knew I didn't like UNIX! Give me an OS where they use real Words for commands, rather than cryptic ones, any day!  lol

Not sure this little digression needs to be placed elsewhere - as, as far as I am concerned, the digression is finished. It's onwards and upwards now!   :)

With regard to running pvs2pvo.py on boot I don't know if this will point you in the right direction....

To get screen desktop access to my pi, I use the TightVNC Server on my pi and TightVNC Client on my PC. To get the server on the pi to autostart you put the file "Tightvnc.desktop" in the folder "/home/pi/.config/autostart". I think you have to manually create the "autostart" folder in the hidden folder ".config". The file contains:

[Desktop Entry]
Type=Application
Name=TightVNC
Exec=vncserver :1
StartupNotify=false

So presumably if I add something similar for pvs2pvo.py then it too will auto start. I'll give it a go later and let you know what happens - if you don't try it first.  ;)


So thanks once again for your help!

Cheers, Jim

Glad you are up and running.

It's been my first full uninterrupted day of running and I'm pleased with the tracking and inverter comparison.

My inverter reported 1.85KWh, the Smart PV display registered 1.70KWh and PVOutput reported 1.739KWh.

In addition, generation and usage tracked quite nicely as I'm running an Optimmersion that uses most of the excess generation.

(http://s7.postimg.org/msu20vp53/image.jpg) (http://postimg.org/image/msu20vp53/)

I also aded an EOD update which is work in progress. It will be interesting to see what that reports for daily consumption and generation. I'm not planning on releasing that as its really a check as the intraday updates generate most of this info automatically anyhow so its kind of redundant.

I'll add an auto start script soon on my unit but I'm happy with it just sitting on my desk running merrily away. Looks like the crontab file may be simplest place for this and piping output to a log file.

I'm quite pleased with my two or three hours work and tempted to get a second Pi for other projects.

Cr** - my Sky broadband is down and the useless people at Sky say it will take up to 5 working days to fix as they say there is a fault near my house. Thankfully I have temporary access via an iPhone Three Mobile teather that oddly enough, works very well even though its via a signal booster that, wait for it, uses my Sky broadband connection.

Me thinks they are either very clever at Sky having invented a piece of copper wire that can distinguish between certain websites and only let certain ones work but not others or, they are really stupid at Sky and found a minor fault cos it was easy to test my line but cannot work out that there is a much more serious fault preventing me from accessing 90% of the worlds websites. And yes, I have tried all the obvious and not so obvious things...

Is it Sky or BT Openreach?

I reported a Sky line fault this summer on a Sunday evening and BT Openreach turned up on Monday morning.

I suspect that there is a backlog of fault repairs due flooding just now.


Title: Re: Eco Eye PV Smart
Post by: ianh64 on January 09, 2014, 01:51:29 PM
There was no fault. It was just an excuse by Sky so that they didn't need to get someone to fix things at the exchange.

Anyway, credit where credit is due. Its all back up and running now - and no engineer was needed to fix the non existent fault at my house. Just a shame they have to make it such hard work to convince them that 10+ devices in the house have not suddenly had their firewalls or parental controls turned on (including internet TV's trying to play BBC iPlayer) and the fact that I get some web sites working but not others (and the split is totally consistent, ie google.com always failed, google.co.uk always worked) and that my mobile phone (and mobile internet) works fine through the broadband VPN signal booster probably means that the fault does not lie in or near my house no matter what their check list tells them they must check.

Anyway, unfortunately PVoutput updates from my Pi/Pthon script has not restarted after the 12 hour outage and as I was running headless and without telnet enabled, I won't be able to ses what went wrong until I can connect it all back up again.

Hi

It looks like you are failing to connect to pvoutput. Its indicating that the connection timed out, that is, it tried to make the connection and waited for a response until a period of time in which it gave up and you got the error. I have a later version (that I will post quite soon which I want to add temperature to that is not top of my list of work priorities so a weeks time maybe) that handles this error a bit more gracefully in production (although in your case, the stack dump gives lots of info to diagnose which is better for getting up and running).

I don't know the reason for the lack of connection, but normal candidates are being unable to connect to the server due to no internet connectivity such as no network, firewall, wrong server address or simply the server being temporarily unavailable.

Sorry not much help, but try ping(ing) pvoutput.org from the Pi just to make sure that basic network connectivity is present.

I've added a modified version to the Home Automation and Monitoring section.

Its a little more robust but most importantly adds temperature logging using observation data from the BBC Weather website.

Hi Guys,

I am also using the eco-eye to upload to PVoutput but am doing it slightly differently.
1. I've connected it to my FreeNAS home server as its always on anyway.
2. I send the data to Xively and get PVoutput to get the data from Xively.  It means I can upload data as frequently as I like to Xively and PVoutput gets the average usage over the 5 minute period.  I upload every minute so far and that seems to catch the kettle been on quite well.

If anyones interested I can post the script I use, its only a few lines long.

Kevin

I'm curious as to what is causing the oscillations in your used power. Your usage curve is otherwise pretty flat compared to mine. Are you or other systems doing any filtering or is it raw instantaneous power?

My main outputs use a basic averaging over the period but have experimented with instant power (very peaky) and a kalman filter (too slow to respond). Not sure if there is a better way that will track the readings better but will filter out some spurious peaks and troughs as a cloud quickly passes.

I ilso assume that your panels are not at 1degree pitch as your generation values are way higher than estimated on the insolation graphs?

Hi Ian,

A tropical fish tank 200W heater  ;D

I sample the eco-eye every minute and upload it to Xively, PVoutput then takes the average of the last 5 minutes.  Not sure if its Xively or PVoutput that is doing the averaging but it seems to work pretty well.  I obviously have the 4second data directly from the eco-eye if I want to look at anything in particular.

Your right, as far as I know they are at about 30 degrees (updated on PVoutput).  Not looked at the Isolation graphs before.

That's really interesting to upload data via FreeNAS. Does anyone know whether this is possible to do with a QNAP NAS. I have a TS 412 http://www.qnap.com/en/index.php?lang=en&sn=822&c=351&sc=514&t=522&n=3415&g=2 (http://www.qnap.com/en/index.php?lang=en&sn=822&c=351&sc=514&t=522&n=3415&g=2) which is also running 24/7 so this would be an ideal solution.
If technically possible the only (major) issue is I have no experience of programming or installing scripts  ???. Any advice or help anyone could give would be appreciated.
Thanks

Title: Re: Eco Eye PV Smart
Post by: ianh64 on January 28, 2014, 09:21:06 AM
Any device would need a serial port in one form or other. Either a custom cable to on board serial port or a USB port with drivers for prolific chipset as used with the USB/Serial cable supplied with EcoEye.

You may fall foal of finding suitable drivers for QNAP but you may be lucky that its a fairly standard Linux installation so will have support.

[edit]I just did a search and found this (http://forum.qnap.com/viewtopic.php?f=24&t=57934). Looks like it may be technically possible but all a bit hit and miss. Also looks like its not for the technically feint hearted!

Good news that if you do get it working, Python seems to be available so my previously posted Python script for RaspberryPi may work.


Title: Re: Eco Eye PV Smart
Post by: Arny on January 29, 2014, 08:31:24 AM
Thanks Ian,

I read the same forum topic yesterday after reading your post and came to a similar conclusion that it may be possible but its certainly not going to be a walk in the park!!

Can I get this straight, if I am able to successfully install the drivers for the prolific chipset I should then be able to install Python and potentially run your RaspberryPi script?

Sounds like it may be a solution but as I mentioned back in my first post, it is certainly beyond me at the moment. However, I am willing to give it a go. I guess my first hurdle has to be getting familiar with Linux command line!

Thanks again
Nige


Title: Re: Eco Eye PV Smart
Post by: ianh64 on January 29, 2014, 08:42:05 AM
Whilst researching your post, I saw that QNAP offer Python on their list of apps.

The pre requisites for my app working with PV Smart are:
  • Python 3 (or later) - there is nothing specific to Python 3 over Python 2, but some syntax and libraries will be different so source will need changing
  • The PySerial python library. There seem to be a number of different ways of installing this
  • Prolific driver for the EcoEye USB/serial cable. Not sure how the optional Windows 8 version is different
So providing that these can be satisfied, then I believe that my script should run OK.

However, the device name of the USB/serial may differ (don't think it does with qnap) so this would need to be identified and changed in the code.

In addition, you will probably have to investigate a way to get it to auto start if that is what you want to do.

Alternatively, RasperryPi, SD card, case and power supply is about £40 if you cannot get qnap to work.


Title: Re: Eco Eye PV Smart
Post by: Arny on January 29, 2014, 08:57:44 AM
Looks like its Python version 2.7 available in the QNAP Apps.

My original plan was to go down the RaspberryPI route but the possibility of running it through the NAS has got the better of me. I must be stupid!!!

Anyway its great to have the option of the RaspberryPI if all else fails. Thanks for providing the script, its appreciated.

I feel its going to be a slow process but may be worth it in the end.

Hi All,
Looks like you are having fun!
The Eco-eye Pi programs are almost finished - I am just doing the web configuration and deciding what bits to release.
In the meantime a few things:
I have stuck with python 2.7 as compatibility with add-ons is still better, particularly pyserial.
The standard Eco-eye usb cable has a prolific chip that will work with everything except Windows 8 but the Windows 8 one will work with everything.
Hope that helps

I bought a SmartPV a week ago and all seems to be going in the right direction, I have had the main 4 digit display go blank on mine a couple of times, button pushing brought it back to life.

My Samil inverter is showing 7watts on Smart and 5/6watts on PVoutput all night, I did try to trim it out in PV but that doesnt seem to have worked, I would like to see it gone in SmartPV too if there is a way to zero it.

Connecting my Samil inverter by serial to their own samil solar browser software gives a difference in PV output of around 35w compared to the SmartPV. 200w on the Samil software is 235w on the SmartPV. I would think the Samil readings are more likely to be correct, so any way to adjust the smartPV to suit?

Not sure I have filled in the costings area of PVoutput correctly either, i'm on 14.9p &4.64 and 13.293 from the grid if someone on the same tariff has a correct screenshot it would be helpful.


Title: Re: Eco Eye PV Smart
Post by: ianh64 on February 03, 2014, 09:20:51 AM
I get a reading when PV is generating too. When I first got my unit and temporarily installed it, I don't think I got the reading, but when I moved the transmitter and clips to a more permanent location, I started getting readings between 2 and 7 W during non generation hours. Over the weekend, I repositioned one of the clips and now it pretty much stays on 7W. So I think that it could be down to positioning of clips.

I then discovered that the generation meter could consume 5W and inverter 7.5W and thought that was it as I had thought that my temp install was before the meter hence including gen meter use. However when I went to reposition things over weekend I realised that I only have individual tails one side of the meter so this was not down to positioning clips one side of gen meter or other.

On my RasperryPi logger, I deal with situation with pvoutput by setting gen readings <7.5W as a 0 reading.

I spoke with Peter asking if PV Smart could detect this situation (possibly detecting reverse polarity in gen lead) but it sounds like its more complex than that and that Trax itself possibly filters at 20W.

Doesn't explain why I didn't have issue when I initially connected things up. So suspect that positioning of clips does affect this but I cannot remember the positions I initially used to resolve it. I've just learned to accept 2-7W on display as being 0 (clip based monitors are not accurate below certain level of W) and filtering before sending to pvoutput resolves spurious nightly generation.

The ecoeye only has a serial connection that either connects to a PC running the ecoeye trax software or to another device such as raspberry pi that can log to an external server. From this a web browser could access the data in real time, but there is nothing that works like this at present.

Whilst trax is real time, you need to use the supplied cable and is not browser based.

I did plan to add an iOS app to access my python script in real time however since hearing that the ecoeye offering might contain web server I decided to wait to see what that offered. But I think that either of these would require purchase of a raspberry pi and power supply (about £45) or a PC running 24/7 to facilitate either of these options as ecoeye has no wifi or network capabilities in its own right.

At the moment the aux socket is not in use and there is no firmware to use it. We are looking at using it to monitor the power being used by immersion controllers but there are some technical problems in both the transmitter and allowing for the extra data in the transmission and the storing of it on the card. No quick fix I am afraid.

Ive got optimmersion and EcoEye. Optimmersion does the basic functions of EcoEye but is ugly as anything and you wouldn't want it in you kitchen etc. But as well as controlling immersion, the wireless versions can control the optiplug devices but i cannot personally think of a use for one that the variable throttle cannot better control. Obviously optimmersion is more expensive and needs professional fitting if throttle is being used.

You may have the same problem im having my ecoeye unit seems to be dropping the signal occasionally when it does this it just hangs until I press the
green button then it will good for a period of time I have fitted new batteries in bot transmitter and head unit but still happens occasionally there is less than 15 feet between my unit and transmitter this started to happen after running faultlessly for over a year in the same positions it is quite annoying

Same here communication with the sender is really hit and miss and very unreliable. Right now I feel it was a waste of the purchase price. I use a USB bluetooth device on the computer and its communication is rock solid and its three times further from the inverter than the eco-eye sender and base unit are apart and it has a floor and an extra brick wall as the crow files between the two.

Sorry for opening up a new thread, but there's already a lot of Eco-Eye expertise here.

Have any of you managed to 'sniff' and decode the 433Mhz data from the transmitter?

I really like the sensor bit of Eco-Eye - the fact that it senses voltage, so can cope with funny power factors, and knows the difference between import and export. That bit is brilliant - better than anything else I've found.

But I really don't like the display, and if I want to log the data I find the serial lead really clunky. So it would be great to just be able to sniff the data using a Raspberry Pi or Arduino or similar.

Anyone tried?

Thanks,

P.

Hi Paul,

I've not done that but there is no reason you can't use the raspberry pi to pull the data from the eco-eye display using the USB cable.  I have one plugged into my NAS box doing exactly that, its stuffed down the back of my sofa which is great apart from every now and again it loses connectivity with the transmitter and I need to push a couple of buttons to get it to re-connect.

Would be interested to know if you manage to do it though.

I suppose that could be a last resort. But it just feels wrong. It's 2016 - we shouldn't be pulling data from wireless devices using serial cables!

Has anyone tried the EnergyHive Hub?

I have my Eco Eye connected to a homeserver but it still ocassionally drops the signal though it's a lot better in the winter than summer for dropped signals (for some reason). I wonder if this EnergyHive feeds PVOutput?

When you say it drops the signal, are yiu talking about between transmitter and display? Ie display loses the antenna icon until you press one of the buttons on left of display?

One of the reasons for this seems to be instability in the power supply - i run my transmitter on a transformer so dont know if its due to the transformer temporarily tripping out of something on the clamp side. On really bad outages, i have needed to reboot the transmitter but thankfully these dont happen that often. Thankfully pvoutput notices outages > 15 minutes and emails me so i can act at earliest opportunity.

The energy hive hub looks to be possibly energy hive specific but give ecoeye a call - they are quite helpful.

My Raspberry Pi solution (ianh64's pvs2pvo original version) has been running 24/7 since mid April (a planned upgrade of the Raspberry Pi UPS firmware) and its only missed a few sets of data. Im so pleased with reliability that I have not bothered to install my next development version which will buffer internet outages and allows other sensors to be monitored. I dont think the energy hive offering will do a better job.
