Which smart thermostat to control floor heating

Hi, my new home (in Switzerland) has floor heating and an option to control the temperature in every room with a thermostat (has the fittings for it but not installed). The previous owner used to regulate the valves of the floor heating in the basement manually. It also has a heat pump and a boiler to warm up the water.
I would like to ask you which system would you suggest to regulate the valves automatically for every room. It goes without saying that the system should be compatible with HA.
About a year ago I saw someone posting a solution from a company in Netherlands but was not able to find it.

Thx in advance.!

My suggestion would be to take a look at Plugwise: https://www.plugwise.com/smart-thermostats/?lang=en
