I have just received a set of 3 IAMs and one EnviR monitor/display. The monitor readily detects the sensor for the fuse box/meter cable, and gives sensible looking readings as the house power usage varies.
Unfortunately I have been unable to get two of the three IAMs to pair with the monitor. I have had the monitor and IAM next to each other (adjacent wall sockets), and have followed instructions to pair them. The appropriate things seem to happen with regards to red LEDs flashing (although the red LEDs seem to be predominantly "off", and flashing "on" rather than the other way around), and the monitor's display showing a tuning animation. However, when the tuning animation finishes (maybe taking about a minute or so) the monitor's display does not register 0 watts as it is stated that it should.
Edit: added the following:
In addition, the instructions I followed are as at:
http://www.currentcost.com/media-centre ... asheet.pdfThe IAMs themselves have "V3" on the back, just next to (what appears to be) the serial number, whose prefix is TIAM9904
The monitor seems to pick up a reading from the whole-house sensor quite happily, and will relay data for it to the serial connection every 6 seconds (as expected). However, I have at best managed to pair it with only one of the 3 IAMs, and the updates I receive from the one that appears to have paired seem to only update fairly infrequently (varying between 4 minutes between readings, down to 30 seconds, with no apparent pattern). The value it reads from the IAM appears to be sensible, however.
