Shelly Switch Thermostat/HVAC

Does anyone know if I can install a Shelly Switch on the thermostat wires, to be able to control the HVAC via HA?

I have temperature sensors throughout the house and would like to be able to control the HVAC without buying an entire “Smart” thermostat. Thanks in advance.

I am actually thinking about going down that route as well.

As long as you only need On/Off States for your HVAC, it should be working.

Anybody did this already?
