[BUG] Homebridge 1.3.0-beta 40
Testing Homebridge 1.3.0-beta 40 and I got this message in my logs:

`Received warning for the plugin 'homebridge-pihole' from the characteristic 'On': SET handler returned write response value, though the characteristic doesn't support write response!
[On@Homebridge 9A0C] SET handler returned write response value, though the characteristic doesn't support write response!`

Anything is working well though.
