I've had a CT-80 thermostat with a Wi-Fi USNAP module operating with my Vera system for the last few years without issue, minus a rare disconnect due to loss of power. As it's running on a wifi module, I use the Radio Thermostat plugin through Vera to sync it to my set-up.
Lately, my CT-80 has been disconnecting more frequently from my Vera network. What I mean by that is that although the thermostat will continue to function manually, and even over wifi (via the radio thermostat app or website) it looses it's connection to the rest of my Vera system in that the ambient temperature, set-points, etc. will not update or change in the Vera UI or over my home automation apps.
Unfortunately getting the CT-80 back in sync with Vera is not easy, and for some reason seems to becoming more and more difficult. I basically have to start the set-up process for the CT-80 all over again from scratch (hit the reset button, log in to the wifi network from the thermostat, enter the PIN, and let it finish the set-up process...). But no matter how many times I do this now, again my CT-80 will work via the Radio Thermostat app or Radiothermostat.com but I can't do anything with it over Vera. The last time the thermostat lost functionality with Vera about two weeks ago (again for no apparent reason), I re-did the set-up, let the unit sit overnight, and then for no reason in the morning hours later, it again functioned with Vera on its own.
Has anyone else had any issues with a CT-80 operating in a similar set-up? I'm beginning to think that for whatever reason the wifi USNAP module operating with the Radio Thermostat plugin in Vera isn't working well with my system anymore for some reason (maybe due to a Vera UI7 firmware update?). Would a z-wave USNAP module for my CT-80 be a better option as it would add z-wave functionality without the Radio Thermostat plugin work-around? I utilize my CT-80 to work with several Everspring ST8-14 temperature sensors in that I can remotely force the CT-80 to read the ambient temperature of those sensors rather than it's own reading to help off-set the fact that my home only has single-zone heating/cooling. Would I still be able to utilize the CT-80 like this with a z-wave module installed vs my currently installed wifi USNAP module?
