Hello,
I want to exchange my old under wall mounted thermostats (230v) controlling my floor heating. Issue is, that I have a combination of thermostats and light switches in a double frame. (I could explain way better in German, hope you know what I mean). Edit: here is a picture to clarify:
Most of the smart thermostats don’t fit into my frames (5.5cm x 5.5cm) except for this one I found:

Homematic.
As I don’t have any other homematic products I don’t want to set up a ccu or buy a stick and run raspberrymatic. Also they are like 80 euros a piece and I need 6 of them…
Do you know any thermostats with 5,5cm dimension running zigbee (zigbee2mqtt with sonoff USB stick) or wifi and are compatible with home assistant for a reasonable price?
Thank you, I love home assistant and this community, even for a non tech guy like me it’s doable with some effort
