Hi folks,
do you know if this device is already integrated, or someone already using it?
It seems promising

It’s the Danfoss LC13. I got one for testing.
The Danfoss is in the Openhab database, inclusion in the network is a breeze. The LC13 setpoint is being updated by a rule. The device does not not report the actual temperature (at least not in my case;-).
And it needs to have a direct connection to the controller. Depending of the size of the house this could require careful placement of components.
If configured correctly, it shouldn’t (I think) need to be in direct connection with the controller once it’s configured.
My house is too small to test ;-(
