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.

    My setup is a bit different but I had a lot of fun putting it together. I have a D1 mini with a switch hat wired into the boiler.

    The D1 runs a tiny web server that lets me turn the heating on and off. Then I have a bunch of ZigBee thermostats around the house that provide a fuzzy average temperature.

    Then I have a custom dash in hass that displays pretty much what a hive would display.

    Whole setup cost about $20 and has been running nonstop for over 5 years!

      Mine is also different.

      I got a Google Nest E thermostat off eBay from a charity shop for £12 and wired it in to where my old dumb dial thermostat was.

      My ZigBee thermostats are just my ZigBee motion and door sensors that also have a temperature element.

      I turned off the Nest smarts in Nest, and had HA come up with average temperatures for the whole house using the ZigBee things, then recreates the smarts in HA.

      The Nest E smarts stopped working 6 months later but the heat link still worked, so I bought another off eBay for £20 and paired that.

      I am gonna just get some ZigBee temp sensors at some point, but this works well enough for now.

      Yeah, I suppose one could do a generic thermostat in HA and use just a few smart switches. However that requires some rewiring of the previously thermostat-controlled device.

        In my previous house, the v1 prototype was wired straight to the boiler as there was no previous thermostat. In the current house, the v2 is wired to the Honeywell, so one can override the other as they are in parallel.

        It was pretty finnicky stuff and I had to scour the internet for decade old wiring guides, but I like that sort of thing so it was good fun.

        Every solution is a good solution if it makes your life easy and you have fun installing it!
