A simple python script to synchronize Mopidy and Shairport-Sync media players. This script will monitor each player activity and once a player starts playing it will stop the other player.

You should use it as a daemon for example :

shairmopd &

Or the following systemd service file :

[Unit]
After=shairport-sync.service
After=mopidy.service

[Service]
ExecStart=/usr/bin/shairmopd

[Install]
WantedBy=multi-user.target
