MQTT controlled Multi-Room Audio based on Airplay/Airtunes 🔈
This is a little daemon that can retrieve an audio stream via TCP socket or from a Alsa Loopback device and stream it to Airplay/Airtunes compatible receivers. Via MQTT you can control the receivers volume and enable/disable the receivers. I'm using it in conjunction with Mopidy to create a Multiroom Smarthome-integrated audio playback system with several Airplay Speakers.
Based on lperrins node_airtunes - all credits belong to him. Also thanks to Adam Duncan for creating a fork that works with recent versions of Node.js.
Prerequisite: Node.js >= 6
$ sudo npm install -g airtunes2mqtt
$ airtunes2mqtt --help
I suggest to use pm2 to manage the airtunes2mqtt process (start on system boot, manage log files, ...).
