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?


I’m currently using a Meross thermostat as it was relatively cheap: https://shop.meross.com/collections/smart-thermostat/products/matter-smart-thermostat-mts300ma
Currently using the meross_lan (https://github.com/krahabb/meross_lan) integration to make it work because my LAN doesn’t support Matter.
