I have one over complicated in floor heater that requires 2 signals to control, one for opening radiator valve and second to enable fan to blow air through it.
there is only few thermostats dedicated for such setup that are extremely expensive and I decided to make my own that is also better.
i have 2 temperature sensors connected, one to monitor room temperature and the second touching radiator inside, then I'm able to open valve when room temperature is below threshold and wait until radiator is hot enough and we are trying to heat for few minutes (without fan this will also work but less efficiently, but will be silent) then when temperature is reached I close valve and keep fans on until radiator cools down.
I also have temperature reported to home assistant where I have pyscript automation that controls AC based on multiple temperature sensors, open window sensors, humidity, presence, time, etc to most efficiently cool down my apartment
if you need to get signal on a wire, you can output it from the same device, from other esphome device or through home assistant using integration.
