Screenshots

Known flaw:

With fan.turn_on and fan.turn_off the state reverses instead of the state going to the correct value. I haven't had time to find out if this is a general problem with fans or only with this device. However, since the device beeps every time the state changes, it is better to first check the state in an automation and only transmit state changes.
