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.

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.

Thanks! Per my other comment, I guess I've gotta look at Z-Wave if there are no wifi-only options available. Checking out the T6 Pro now

Another +1 for the t6. It's been running great for 6+ months

I have been extremely satisfied with my Honeywell T6 Z-wave thermostat.

Completely local. No vendor phone apps. No accounts.

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.

It's more of DIY solution, but works fine, did you check with https://esphome.io/ if your heat pump system couldnt be connected ?

Most of them have a way to communicate as they already have an offline thermostat

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

What Zigbee thermostats do you have?

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.
