Thermostats are showing up in Humidity sensors

[djsomi]

Hi All,

Recently I've discovered that, thermostats are popping up in the humidity category, with 0%.
Anyone else experienced this?

Interesting. What App is that?

I have just notice the same thing humidity icon next to temperature icon. If I click on the humidity icon brings up the temperature adjust page
This only happens on iPhone running ios16 the app is apple HomeKit app
On iPad which runs iOS 15 the humidity icon does not show

Okay, I have found the page you are referring to. The behaviour is correct, as being a thermostat now implies that you can measure humidity as well. I have not found a way to disable it as of now. Any ideas?

I dug a little deeper:

HAP-NodeJS defines a Thermostat the following way:

/**
 * Service "Thermostat"
 */
export class Thermostat extends Service {

  public static readonly UUID: string = "0000004A-0000-1000-8000-0026BB765291";

  constructor(displayName?: string, subtype?: string) {
    super(displayName, Thermostat.UUID, subtype);

    // Required Characteristics
    this.addCharacteristic(Characteristic.CurrentHeatingCoolingState);
    this.addCharacteristic(Characteristic.TargetHeatingCoolingState);
    this.addCharacteristic(Characteristic.CurrentTemperature);
    this.addCharacteristic(Characteristic.TargetTemperature);
    this.addCharacteristic(Characteristic.TemperatureDisplayUnits);

    // Optional Characteristics
    this.addOptionalCharacteristic(Characteristic.Name);
    this.addOptionalCharacteristic(Characteristic.CurrentRelativeHumidity);
    this.addOptionalCharacteristic(Characteristic.TargetRelativeHumidity);
    this.addOptionalCharacteristic(Characteristic.CoolingThresholdTemperature);
    this.addOptionalCharacteristic(Characteristic.HeatingThresholdTemperature);
  }
}
Service.Thermostat = Thermostat;

../homebridge-evohome/index.js contains the following:

    // this.addOptionalCharacteristic(Characteristic.CurrentRelativeHumidity);
    // this.addOptionalCharacteristic(Characteristic.TargetRelativeHumidity);

Looks like I have disabled humidity already. Perhaps HomeKit simply groups the accessories by what it expects them to show, not what they actually emit. I'm affright, there is no simple fix for this as of now.

@djsomi @5xPa does this cause you any problems, or is it just an aesthetic thing?
