to control my floor heating I’m looking for smart thermostats for surface/on-wall mounting.
I had one in wall where I installed a MCOHome which is quite nice but all my others are surface mounted but have live power and the control wire to the valve. In best case I’m looking for a direct replacement with at least manual thermostat control but also connectable via Z-Wave. Alternatively Zigbee because those two technologies I already have infrastructure for. Anything else might be an option if it can easily be connected to openHAB.
It seems very hard to find something like this. In case anyone knows about an option please let me know.
