"imeasure" Quite interesting

[petertc]

john, that would be cheating 

add imported plus total production then subtract the exported meter reading.

I disagree ! Your home generated power has produced no co2 (apart from production of pv) so why add it in?
imeasure is a measure of household co2 not electricity used.
rgds George.

Two opposing views, I see. 

George, I now see why you rank in the top 5 where as I linger in the bottom 5. 

To be honest, I use it as a power used comparison and a way of seeing if I am using less power than a year ago because of increased insulation and other energy saving measures. 

I shall wait and see what others do.

Hi all
I just put in Import  minus export as the electricity amount.

George,

that's an interesting thought as it is measuring CO^2 , but in other ways i am with John as a way of checking total energy usage ,

may be worth an email to imeasure to see  if they can add in production and export readings and subtract these from the CO^2 reading.

Or else i can just keep running my own spread sheet for total usage.

[ecogeorge]

I wouldn't deduct any exported , that's a bit of a greyer area! but would just count electricity imported from the grid. If you have produced clean electricity and used on site then I wouldn't count it.
I am on a 100% green tarrif for imported electricity so I supose strickly speaking my co2 is zero ?

Hi
I sent an email yesterday to imeasure to see if they will incorporate people with renewables and also the FIT structure. I also sent an email a couple of months ago with not much of a response. Will wait and see. Will post if I get an answer.

Hi
Still haven't had a reply.  Will see tomorrow if it copes with a minus reading(my first one). My import minus export in now in minus figures this week.

Is it me ? or has  the imeasure website crashed? my saved link comes back as website not found ??

[Iain]

Hi
They have updated their website. It is working for me, but I just typed imeasure in google to get there. They do allow -ve readings. So all seems to work for import - export.

I am getting fed up with Imeasure.  It does nothing useful for me.  All it gives is a week by week comparison to an average.  It does not really take into account heavy or light weeks eg when away for a few days or when eldery visitors are staying and the heating is turned up.

I have made a sensible suggestion to them but apart from saying it is interesting they have ignored it. 

At the moment they give annual consumption with the start date being the date of my first meter reading.  Instead, I have suggested that it is on a rolling basis as the last 52 weeks consumption.  This could then be prepared with the previous 52 weeks.  Not just for me but everyone else with two years history.  Then I could see how my change in usage (approx -12% electricity and -8% gas) compares with the rest of the Imeasure population.

Anyone else think this might be more useful? 

I appreciate it needs two years of data but many of us have this and imeasure are able to interpolate from monthly history if that is all one has.

Hi
At least you had a reply from them!!!
I am still waiting after 2 emails.

I'm also having trouble with the graphs not displaying and have used the imeasure carbontalk forum to report the problems.  Seems to be quite active today following the recent site updates!

I agree with the 52 week usage suggestion - or even one where you can input your own from/to dates so you can make comparisons over the same period year on year.  (I have maintained my own spreadsheet for a number of years and it's v. useful to see what effect the various changes to the house/insulation/ plumbing/heating/appliances... etc. have made to consumption.  e.g. I'm using >40% less gas since mid 2007 than I was in 2001. But it still costs more!)

I have an issue with the way imeasure calcs the costs of gas & elec.  It uses the price per kWh most recently entered and applies that to all the historical data when it tells me how much I've spent.  It would be useful and more accurate if it could take account of price changes from the applicable date and store the historical prices input for earlier periods and not lose/ignore them.
