I have a Honeywell T6 ZWave thermostat and HA automates it just fine and I can control it with the entity or dashboard card. I have Google and Alexa connected and they can control the thermostat but when I use assist alone or with a LLM it says it is making the change but never does. It’s properly connected exposed as Google and Alexa have no issues.

Any idea what the issue may be?

I’m not sure of what to look for but I will test assist doing it and see. Thx.

I don't have z-wave, maybe someone else can chime in, maybe try to update the z-wave addon?
