Hi! I am running Umbrel on a Raspberry Pi 4 and I have “Home Assistant” installed in it, I oly have some smart lights connected to it. I would like to integrate a Thermostat with HA. But I am a bit overwhelmed with the different types of connections (Z-wave, Zigbee, Wifi, …)
Do you guys have any kind of recommendation, what connection is better? I would like to keep it local (or connecting remotely via Tailscale) but I would like to avoid any cloud or third-party server solution.
What thermostat hardware can I buy?
The other recommendations are good, but please please double check your tstat wiring and/or HVAC system to ensure they are compatible. One of the few stats that work with my system without shenanigans is the Honeywell T10 Pro (which also worked out of the box with HA). This required me to rewire the control run to use it, and is not something I would recommend for people who aren’t prepared to cook the control board on their furnace if they do an oopsie or regularly read electrical diagrams.
