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 seem to remember that the Honeywell T6 Pro Z-Wave comes up a lot when this question is asked. I’m not running Z-wave yet, though, so I can’t comment.

    I believe there are a few Honeywell models that are Z-Wave, so that’d be fully local. I’m using EcoBee, which does have cloud control, but I’ve added it to Home Assistant via HomeKit, and that is local control. It’s a little annoying because EcoBee doesn’t expose it’s fan setting via HomeKit, so I can’t have HA kick on the fan when the AC isn’t running, for example.

      Thanks - I’ll take a closer look at Z-Wave again. I’m only running wifi based devices so far but if this is the only way to get better thermostat control I might have to compromise.

    I have two Centralite HA 3156105 ZigBee ones I use for two zones. They work pretty well. They are the older Centralite units with xfinity markings on them, can be found on eBay for about $15 - $20. Both Z2M and ZHA support it.

    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.

    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
