I recently installed line-voltage underfloor heating with the assumption I'd easily be able to swap out a smart thermostat and link it to Hubitat. Turns out it wasn't so simple - all I've been able to find is MySa, with a closed API.
To make matters worse, I also have a baseboard heater installing soon, which will also be line-voltage and my contractor didn't even include a place to put the thermostat.
My preferred solution would be to have a smart thermostat directly controlling the underfloor heating, monitoring the temperature sensor from the floor, and also able to report room temperature so that I can handle the baseboard using a regular smart switch and Hubitat.
Can anyone recommend anything? I am in North America so this option probably won't work: Thermostats - Heatit
I'm desperate enough I even started looking into whether I can build my own device using a Raspberry Pi zero in a junction box... how hard could it be to get a room temperature sensor and the floor heater plugged into the Pi and then code up some local control / connect it to Hubitat?
