Does anyone know how to read the control setpoint from a Thermosmart thermostat? I want to use this for controlling heat pumps, and am sure the thermostat must command the supply water temperature to the boiler because it can modulate and keep the room temperature steady.

I know the Plugwise Anna thermostat allows you to see the control setpoint. It should be msg1 in the opentherm protocol, if I'm not mistaken.
