Recommendations for self-hosted Thermostats (North America) - Lemmy.world

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.
