Question about Netatmo Smart thermostat

I live in a rented flat that uses underfloor heating. I have a room thermostat in each room where I can regulate it with a rotary wheel (clicks at a certain point - on/off). I now want to make the system smart -> do I have to install a smart thermostat in each room and that's it? This switches on/off and I don't have to change anything in the central flat unit of the underfloor heating?
