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!
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!
