I guess you have the bridge linking to my.currentcost.com ?
My shared output is like this http://my.currentcost.com/device/10202
Possible wireless interference between optismart and envir?
Also do you have the USB cable for your EnviR?
If yes, you could check the stored meter reading data in the optismart and compare it again 24 hrs later to see if it has gone up by the same amount as your meter (read meter at start and end of test).
The OptiSmart stores the meter pulse count so if you record this value and then do the same 24hrs or more later the value should have changed by the same amount in kwh that your meter clocked up in the same time period (divided by 1000 or whatever your meter pulse rate is per kwh).
The "C2 Terminal" program will do to check the data http://currentcost.com/software-downloads.htmlhttp://currentcost.posterous.com/optism ... developers
tells you which bit of the output to look for in the "under the bonnet" section.
