GoControl GC-TBZ48 thermostat - no temperature updates unless I restart HA

Seems that others have communications issues with this thermostat by my situation is a bit different - I’m not getting an update in the current temperature unless I restart HA.

It seems like other data makes it back to HA (like current set-point when changed on the unit), but ambient temperature never updates unless I restart HA, then I get the current value.

Ideas?

Are you using the thermostat on battery power or powered off the HVAC wiring.

I experienced similar issues as your describing when on battery power.

I assumed that the thermostat only updated when a major change happened, similar to other battery powered zwave sensors.

Thanks silvrr - the unit is powered from the HVAC. However, then I first installed it I had both batteries and HVAC power hooked up until I realized that was not necessary. Your comment had me thinking, so I looked at the manual again and found this:

“IMPORTANT: If the thermostat is installed on a Z-Wave network, while it is batteries powered, it will
NOT work as a Z-Wave repeater. Do not install batteries and temporarily power the thermostat from 24VAC to include onto a Z-Wave network. Shortened batteries life may occur when 24VAC power is removed.”

I’m interpreting this to mean, if you set up ZWave with 24VAC active, the thermostat is set to a “repeater” mode, i.e.: a high-power mode, which perhaps includes sending constant temperature updates.

Its not a stretch to think that maybe if you start out with only batteries then add 24VAC power, which I did, maybe it stays in lower power mode?

I’m going to try removing from zwave, powering down for a while, powering back up (no batteries), and re-adding the device.

I would try a reset like you mentioned.

From what I recall, there is a way to reset to factory defaults and truly clear it out. I think I did this in between battery and AC power.

I know this is an old thread, but I’m hoping for a solution. Did anyone figure this issue out? I’ve got the same problem. Everything works except the air temperature updating. I’ve tried everything I can think of. Also, before I setup Home Assistant I used Vera and it worked flawlessly. I’m fixing to trash this thermostat if I can’t figure it out. Thanks!

Just bumping this thread. did anyone figure it out?

Way late response but you can force polling of the GoControl. Create an automation thag fires periodically and use the zwave refresh value service to force the thermostat to respond.
