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.

When Lowe's Iris home automation platform was shut down, they liquidate everything. I picked up a couple of CT101's made by Radio Thermostat. They're based on Z-Wave and have been great.

I also have a Honeywell Z-Wave model that our AC service company had to replace when one of the CT101's when they fried it. It's not as full-featured as the CT101's as it doesn't expose some entitities.

Both devices can work with heat pumps.

You can find CT101's on eBay for as little as $23. (Which is a steal, compared the original retail price.) Just make sure that if it's pre-owned that it's been excluded from the previous Z-Wave network. I've found that resetting Z-Wave devices to factory settings can be a PITA.
