Am I right in saying that the wifi version would allow me to:
- link to a 1-wire network with (in my case) 7 sensors?
- access the 1-wire sensor data values over wifi from a PC elsewhere in the house?
- pull data (XML is fine) off the device for processing on the PC?
Yes, yes, and yes.
Does the device actually store any data values - or do you need to keep pulling the data off the device at intervals?
You need to keep pulling the data as often as you want updates - it doesn't store anything.
Now I've used one (and it's in production on a customer site now), this is how it operates.
As soon as it is powered up and running, it just loops around reading all the sensors as often as possible - ie when it's read the last it goes straight back to the first without pausing. In practice, it seems to take about 1 second/sensor so it would be looping about once every 7 seconds in your case.
When you pull the data file, it simply writes the last values it read - so they will be accurate within the last few seconds which is way faster than the sensors themselves will react to changes (thermal inertia and all that).
Sorry for all the questions - having looked at the EDS product website I wasn't much the wiser!
Don't apologise, I know where you're coming from with that !
(For context - I currently have an old laptop which polls a 1-wire network every 5 minutes. It's monitoring a solar HW system - tank, panels, house and external temperature. The laptop is on it's last legs, not helped by being in the airing cupboard! It would be better to access the 1-wire network remotely from my main PC. Running an ethernet cable isn't an option).
Pity a cable isn't an option. WiFi should work (I've only used the cabled version), but I always prefer wired networks where possible.
