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 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.
I have an ecobee that I’m using now, but I do have a centralite pearl ziigbee thermostat. Do you mind sharing your configuration for setting your temperatures? I want to be able to have home mode away mode etc like I do with the ecobee but can’t seem to figure it out.
With the Centralite units I have, most of the config like temp floating point and setting what is exposed is done on the thermostat itself (the OEM manual covers how to set it up). zigbee2mqtt seems to have way more configuration options than ZHA in HA, both pick it to varying degrees.
I would suggest going the z2m route, as that would probably give you the most ecobee similar options: https://www.zigbee2mqtt.io/devices/3156105.html
