Honeywell T6 thermostat - state doesn't change

Configuration Z-Wave
1

I have a T6 Pro (product code TH6320ZW) thermostat connected to HA via ZWave. It all works fine, except the Thermostat State does not change. Specifically:

  • T6 is off, mode is shown as Off, state is shown as Idle
  • turn T6 on - cool, mode is shown as Cool, state is shown as Idle
  • cooling begins, mode is shown as Cool, state is shown as Cooling
  • cooling ends, mode is show as Cool, state is shown as Cooling and never reverts to Idle

Even if I go to the ZWave Control Panel and refresh the operating state, it does not change.

Any ideas what causes this / how to rectify it?

Battery powered or 24 vac powered?

It has both. Battery is showing at 95%.

You may want to try re-paring it and make sure it is connected to 24vac during that process.

I have 4 of these and they mostly work ok.

You should run a polling script every 10 minutes, but since the manual refresh isn’t working for you, then something else is wrong.

I tried re-interviewing and that has seemed to work for now. I’ll keep an eye on it.
