HomeKit Humidifier control

Hi.


Trying to control the humidifier, but faced with some problems. If I use "ServiceType": "HumiditySensor", then my device can only measure humidity. If I add "CharacteristicType": "TargetRelativeHumidity" then Siri can control the humidity setting, but I can not set setpoint it in the application... Please tell me what type of humidifier should I use to control the humidifier?
