Controller for electric floor heating with OPEN THERM - which one to choose?

What type of electric underfloor heating controller should be used so that it can be regulated using the OPEN THERM protocol?

Maybe you can find Link

I have searched, unfortunately without success.
That's why I'm asking the professionals, because if someone is an electrician, he or she has probably dealt with underfloor heating and its control

Ask the same question in this forum : Heating Systems

There they deal with plumbing, and this heating is electric

And what doesn't anyone know about underfloor heating?

I am not familiar with electric underfloor heating - but it seems that the accumulation of such a floor is not significantly different from heating with a water factor?
If the heat output of such a floor is not significantly different from that of a "normal underfloor", then the subject is rather open. Do you want to control each room separately?
What kind of system are you going to connect it to?
kind regards

I have a home automation system based on Zwave, combined with heating control using OpenTherm transmission protocols.
Each room has its own separate thermostat which, depending on the heat demand, runs the boiler at the lowest level needed to heat the room or group of rooms, while also controlling the heat dosage to the room in question in a linear fashion.
This is combined with electric rapid floor heating, which raises the temperature briefly during the bath.

Unfortunately I haven't done anything on Zwave or OpenTherm.
What I don't understand is, if each room has its own separate thermostat, what's the problem of raising the temperature for bath time ? The second thing, the bathrooms are small enough that you can constantly maintain these min. 22 degrees for your own comfort.
What is this "electric rapid floor heating"- do you have a boiler or a storage heater?
