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!
If you find dismissal of your inability to coherently explain the concept you brought up rude, that’s your prerogative.
You’ve said enough to demonstrate you don’t understand basic empiricism, have not done sufficient reading on the topic that - again - you brought up, and have contradicted yourself in your own comment.
You are dishonest, and we’re pretty much done here.
