I’ve been very happy with my EcoBee so far, I moved to it after way too many issues with my Nest. It seems to work just fine with HA.
Time to code your own thermostat.
An esp32, a 4x or 8x relay board, and a 24vac to 5vdc rectifier/regulator and you're golden.
Even has WiFi ;)
I would dearly love to become the hack a board hobbyist that a lot of you guys are, I'm genuinely in awe of some of the things I see people make but it's a little daunting.
I can't solder and haven't even tried. I get confused by the components, ohms and volts flumox me and the one time I tried to code something in ESPHome made 3 lights into bricks.
So I'm very much a "make cool stuff with off the shelf devices" kind of guy.
