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.
Finally I am buying a Meross MTS215BMA with Matter. But what I don’t know is if I will need any antena for Threads to connect to my RPi with home assistant? or maybe this thermostat works with Matter over wifi. Do you guys think if I go with smart devices connected via Matter (I have seen most Ikea smart home devices support it), do I need a Threads hub/antena? If so, any recomendation?
That thermostat should work over WiFi and not use Thread so as long as your network supports Matter, you should be good. If it doesn’t support Matter, you can use the meross_lan integration.
