Since a few days I own a new Home Basic set of Plugwise, Awesome!
But I have a problem with one circle, this circle isn't reporting the current usage and total usage, both values stay on 0,00. No matter what device is connected to it.
I tested a few devices (simple 15 watt lamp, 100 watt consuming Computer, and a mobile Airco (uses way to much

The circle is visible in the Source software and I can switch it On and Off without problems, but no usages.
I tried to remove the circle from the software and re-assign it again, and tried to place the circle closer to the circle+. This didn't help for me, still no usages.
All circles are running the latest FW version (2011-06-27) out of factory and my server is running the latest Source software (2.22). All other 8 circles are working fine! Only one isn't

Is this something that I can fix by myself or should I claim my warranty by Plugwise?
Thanks!
