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?
Definitely Zigbee or Z-wave instead of wifi. Once you start to build out more devices you will be glad to not have gone down the wifi route.
I went with Zigbee and have Sonoff SNZB-02 temperature and humidity sensors in each room that have been absolutely flawless since the day I installed them, and they last about two years on a single battery!
I would obviously recommend them but I don’t have any experience of other thermostats or of Z-wave.
I did also install smart Zigbee TRVs on each radiator but I don’t rely on the internal thermostats of them as they don’t accurately represents the overall room temperature.
If you’re just starting to build out, what about using thread instead of zigbee or zwave?
I second that solution. I’ve built the same setup for my home last Christmas, even tried different brands of TRVs to see which one I like. Works perfectly well with a Raspberry Pi with Home Assistant. The only issues I ran into were my lack of experience.
