Homebridge Apple TV AirPlay Status Sensor

README.md

This setup will add a contact switch to show when your apple tv is playing music over airplay.

The config and script below will give you a contact switch which shows whether AirPlay Music is playing or not.

Follow the instructions for https://github.com/cristian5th/homebridge-appletv, and save your tokens separately from your script.
