Recommendations for self-hosted Thermostats (North America) (self.homeassistant)

Can anyone recommend a thermostat system that is self-hosted (no third-party cloud) and integrates into homeassistant nicely? Something tasmota based would be even better.

This is the final bit of home automation that's been difficult to solve. I've got a heat pump system and there are very few smart thermostat systems that aren't beholden to a public cloud service.

I really like my zigbee thermostats and would recommend them not cloud at all. I have not found a tasmota or esphome compatible thermostat. You could make your our with relative ease use a simple relay board. But I don't think that it would look great

Yeah I've been tempted. I've made other esphome devices with SHT21 temp+humidity boards, and others with relays.

I have a good idea of how to design and implement it, I'm just intimidated by how much a mistake might cost (I recently had to replace about half the components in my system for about $7k)

Wow what all did you need to replace for 7k? That seems really high to me but i guess you could get there with a large very automated home

Relatively big house in the south, so two 6 ton units outside and air movers inside the house both died at virtually the same time. Thankfully I budgeted for it because I knew they were old when I moved in, but yeah lol the cost is making me fearful of poking and prodding ;)

Oh you needed to replace your ac units got it. 7k seem very reasonable for that. I thought you were talking about some home automation equipment that needed to be replaced. I'm glad you had that in your budget. I personal would not be concerned with breaking anything with thermostat even a DIY one as if you have a "normal" thermostat, aka one that did not come with the air handler, then there are no wires that you can touch together at the thermostat that could cause a problem.
