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.

      If it’s anything like my setup (posted in the thread) they’ll have a colder spot in the house, whereas the thermostat is in a warm part of the house.

      My Nest heats to 22 degrees C but the whole house temp is a couple degrees lower than that.

      When the whole house temp hits 20 the heating is switched off, but looking at the thermostat you’d think we’re heating the house to a silly temp, when in fact there’s a disparity between the thermostat temp and the temp of the whole house.

        No, it really is 25° in the two rooms this unit heats up. 🦎

        With that said, the temperature rarely falls below 25°C due to the heat coming off of the neighbouring units in the building, unless I open the window. 🥹

    You know, you don’t have to use the wall plate just because it’s in the box.

    This has been my favorite thermostat. I don’t have a C wire nor an easy to add one in, but it’s AA batteries last for several months and has been very reliable.

      It’s what I use as well — my home was built with a Honeywell Lyric T5 (non-smart), so the wiring harness between the two is identical (including colour), so I just unplugged the T5 and plugged in the T6, did some setup, and it was done.

      Huh, I really like how it looks, besides the large wall plate. 😅

            Patching drywall isn’t really that bad. It’s pretty bad with those plates. Watch some YouTube videos and learn.

              Can patch but it’ll be 1-2 days of work for a good painted finish. Would have to do multiple patching/sanding coats, masking, priming then a couple of rolls of paint of the wall. It’s not trivial amount of work. For a slap-dash finish I could skip some of the steps but then again for a slap-dash look I can keep the wall plates. 😅

    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?

    I like this thermostat except for one issue. When i manually change the target temperature with the HA thermostat card, it has a maximum temperature of 40 degrees. With Fahrenheit, this is obviously no good. it has something to do with the MQTT configuration but i cant figure it out. Luckily service calls in automations work fine.

    Hey I got one too! I took it apart and repainted it black to match.
    For temp schedules I made a local calendar in HA with repeating events with a description of “high” “mid” and “low”. The automation trigger is a calender event that reads the description and sets the temp accordingly

    I wish I could figure out the code to get my T6 to control the Confortotal mini split I got off eBay. I have to think they’re using some genetic code base, but I couldn’t find a matching one.
