I am trying to make sure that my thermostat plugin is compliant with the Thermostat API so that it can be easily used with HS3Touch.

Most everything seems to work correctly. I can change the fan, and mode. When I'm in Heat and Cool modes, I can change the setpoints.

When I set the thermostat to auto change over, the setpoint buttons no longer work.

Does anyone know what is going on under the covers to change the setpoint when in auto mode?
