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?

They're all generally fine. WiFi thermostats open up more security holes than the others because they are designed to be chatty. I have an ecobee WiFi thermostat that's isolated to only talking to HA locally using the HomeKit integration, which is fine, but I can't say I'd recommend it.

When I set up my thermostat the ZigBee/Z-Wave options were quite frankly ugly and had limited wiring compatibility. Nowadays there's a bunch more options on the market - you should be fine finding what you need anywhere.

ZigBee/Z-Wave/Thread are all pretty comparable, so I'd go with whatever you already have on your network - me personally I'm all in on ZigBee right now so I'd probably get one of those.

If you're undecided, HA newest official hardware supports ZigBee & Thread so I'd go with one of those.
