CT30 Thermostat Zwave trouble

Written by on 29th January 2015 in Uncategorized with Leave a comment

I bought several of these thermostats because they are cheap basic ZWave thermostats. Turns out, there is a very specific bug for some of these (including one that I received)! It makes all other zwave devices in your network go offline, because if floods the network with messages!

This only applies to specific firmware versions of the ZWave USNAP module, and only if you are powering it via the C-wire. The fix is to power it via battery (not ideal). In my case I removed the C-wire and stuck in some AA’s and my network came right back and started working again.
