Since about early January, my CT30 seems to lose communication with Vera on a fairly consistent basis. I usually see it when all but 1 z-wave device is not responding. It seems my 1 switch in the garage, about 6 feet from the controller, survives. The garage man door sensor is battery operated but about 3 feet from the controller typically stops responding. The other devices are at least 10 feet away and the furthest is maybe 20 feet away - but the z-wave mesh is pretty tight and I have no issues except this thermostat.
So first time it knocked out the z-wave network, I did an exclude/included of all devices to get them back on mesh. That lasted about week, then the network was down again. Hmmm. Did the exclude/include again, watched it about a week, and noticed it was the CT30 acting up first, and it would take down other devices. Maybe a switch, a motion detector, an outlet, or a sensor. Excluded/included it, the mesh healed, and it seemed to work - for a week.
So focusing on the CT30 when it acted up, I discovered I could unplug the USNAP module, plug it back in, and send a configure node in Vera and it would repair the thermostat communication. I kept an eye on it and for all of February and most of March, about every 5 days, the CT30 stops communicating with Vera, and slowly knocks out most of the z-wave devices. I unplug the USNAP, plug it back in, configure the node, and configure any other nodes that went down. All are back up within 15 minutes. Very repeatable.
So tonight I ordered a USNAP module from Amazon ($20) to see if that is what is wrong with the CT30. If that does not work, I will likely buy a CT100.
Anyone see a similar behavior in the CTx's from Radio Thermostsat?
