Here we go. The setup was pretty trivial. The setup for the Zooz GPIO Z-Wave adapter for Yellow was trivial. Adding the T6 was trivial too. I had to install 2x Z-Wave smart plugs to extend the network from where the Yellow is to where the thermostat is. I used Leviton Z-Wave smart plugs. Finally I added the automation I wanted this whole thing for. Seems to work ™

The only downside I can see so far is that the T6 doesn’t support multi-speed fan (G1/G2/G3 wiring) so I had to choose one of the speeds while wiring and I can’t use the rest. From what I can tell Ecobee seems to be able to use G1/2/3 but I’m not ready to give up on the ethernet-independent operation T6 and Z-Wave allow to have multiple fan speeds.

Does anyone know if there’s a (non-retail) variant of the T6 that supports multi-speed fan?

I needed some thermostat automation done and I stumbled upon this thread. I just attempted this and it went about as smoothly as I can imagine. If you’re also in need of an offline solution, the Z-Wave version of the Honeywell T6 seems to do the job.

    I’ve got a T6 Z-Wave also, controlling a 2-stage heat pump. I have it connected to HA through Zwave2mqtt. It’s been pretty great except for two things:

    A. Changing the time has no effect, as if the clock is read-only due to a hardware issue. I’ve had to set up the daily schedule in HA instead, but it’s probably better that way anyway.

    B. I can’t see the stage and aux heat status in HA. Looks like all it exposes is a ‘heating’ or ‘cooling’ state. Anybody know how to get more info?
