Warning: characteristic was supplied illegal value: number 1 exceeded minimum of 10

After update to 2.7.0

[7.03.2021, 08:42:16] [homebridge-mieleathome] This plugin generated a warning from the characteristic 'Target Temperature': characteristic was supplied illegal value: number 1 exceeded minimum of 10. See https://git.io/JtMGR for more info.

Acknowledged. Being discussed in the discussion forum also. I'm afraid there is no simple solution. HomeKit's minimum target temp is 10°C while we desire a range between 0 and 10°C for fridges. I'm pushing the boundaries of what HomeKit allows.

just adapt min and max value:

The thing is that is exactly what I'm doing already since the first experimental version of Fridge support. So scratch the "just" 😉

Hence why otherwise you wouldn't have seen a temperature dial with a range from 1-9 with step size of 1°C.

The new version at least reduces the amount of warnings by preventing to update the characteristic each and every poll interval. I hope this helps.

Are U Try this part of code for set correct min. and max. value for Target Temperature :

accessory.getService(Service.Thermostat)
  .getCharacteristic(Characteristic.TargetTemperature)
  .setProps({
    minValue: 0,
    maxValue: 30,
    minStep: 1
  });

Thanks, but: yes, that is exactly the code I already had built-in since the first version. (Except with 1-9 step 1).

Is this issue still present for you with v2.7.2?

[grzegorz914]

No,

The warning is gone

Later version returned the problem, but I have finally found the root cause. See #23.
