Humidifier 3c warning and Fan Speed in Homekit
I'm constantly getting "[5/26/2021, 9:05:45 PM] [homebridge-miot] This plugin generated a warning from the characteristic 'Rotation Speed': characteristic was supplied illegal value: number -254 exceeded minimum of 0. See https://git.io/JtMGR for more info."
I connected the Xiaomi humdifier 3c to homebridge-miot. In the HomeKit App the Fan Level isn't shown correctly. It always says the Speed is 0, but i can pull up the bar to set it to a level.
