Hi,
I have the same issues with a Gen2 clamp. Typically after a Vera firmware update the child devices stop reporting. I found that doing a Reconfigure node right now on the main device gets things going again. However, the child devices get recreated with default names and different device ID numbers and thus braking scenes, datamine logging etc.
So I made this little script you can use. Configure it once with the correct values for the names and device IDs. Then when they stop again, do the Reconfigure node right now and get the newly assigned device IDs by altids e1,e2,e3. You plug the new device IDs in the script, run it and you are back in business. The script has values for mine in as an example.
Cheers Rene
