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?


Nest Thermostat Gen 1 or Gen 2 running NoLongerEvil firmware. You can pick up a gen 2 on eBay for 20-30 USD. It only takes 5 min to load the firmware and there is a HA native integration. Rock solid hardware with no cloud, no google, and it works great with HA. Note that the gen 1 and gen 2 are pre Google buyout of Nest. There is also a cloud hosted dashboard if you want BUT there is no cloud self-hosted docker server and no cloud HA only version as well.

Edit: Nest is WiFi
Wait what?!?! I have two gen 2 nests and there’s third party firmware?!?!
Edit: you made my day… Thanks!!!
Nice 👍 been using NLE as a docker server for a while, just switched to the HA integration (note both options use MQTT to allow HA full control with a climate card).
