Tell me how to change values ?
thermostatService = ThermostatService()
thermostatService.set_target_temperature_set_callback(th_target_temperature)
thermostatService.set_target_heating_cooling_state_set_callback(th_target_state)
thermostatService.set_current_heating_cooling_state_get_callback = OFF OR
0: Off
1: Heater is on
2: Cooler is on
can you give a small example?
