Thermostat "No response" in Auto mode

[hjltu]

If send topic: "/homekit/tp-mode-stat" payload: "3"
for statusCurrentHeatingCoolingState.
Then Thermostat accessory show "No response" and sometimes MQTT Bridge also show "No response" and stop working.

No debug output

Please provide debug output that shows the incoming MQTT message and the corresponding HAP actions.

Hi hobbyquaker, thanks for great work.

This is debug output:

// now thermostat is "No response" and show "!" mark

If I change mode(send mqtt messages) and open Home again,
then thermostat will work.

This seems to be "works as designed". The Modus "Auto" is not specified by Apple in the HomeKit Characteristic:

Characteristic.call(this, 'Current Heating Cooling State', '0000000F-0000-1000-8000-0026BB765291');
  this.setProps({
    format: Characteristic.Formats.UINT8,
    maxValue: 2,
    minValue: 0,
    validValues: [0,1,2],
    perms: [Characteristic.Perms.READ, Characteristic.Perms.NOTIFY]
  });

inherits(Characteristic.CurrentHeatingCoolingState, Characteristic);

Characteristic.CurrentHeatingCoolingState.UUID = '0000000F-0000-1000-8000-0026BB765291';

// The value property of CurrentHeatingCoolingState must be one of the following:
Characteristic.CurrentHeatingCoolingState.OFF = 0;
Characteristic.CurrentHeatingCoolingState.HEAT = 1;
Characteristic.CurrentHeatingCoolingState.COOL = 2;

Seems like Auto is only meant to be set on the device, not to be reported by the device as current state.
