Questions about Meross Smart thermostat

Hello, I wanted to ask if the Feller thermostats (what else in Switzerland :-)) can be replaced with this thermostat, does anyone know? I currently have the Feller 4250 thermostat in it. Thank you very much!

I want to replace a 230V thermostat that controls a 380V contactor for a unit heater motor Do you have an item that is compatible with this installation and that the thermostat is connected, so that I can regulate the temperature of my room with an application on my phone?

Hello Galaxus, will you get this product back in the range?
