Sonos Room Volume Synchronize

This is a simple containerized script which synchronizes the volume between two Sonos Speakers.

Quickstart

1. Have docker and docker compose installed.
2. Copy this repository
3. Change HostName and SlaveName to name of your speakers.
4. Run docker-compose up
5. Volume of second machine should synchronize every time you change the volume on your host machine.

Warning

This program currently only works on native linux machines. like a raspberry pi or a debian linux machine. Virtualisation like WSL2 doesn't work, because virtual linux environments create their own virtual network, which breaks the SoCo discovery and the event listener.

Detailed Installing process

Step 1. Install Docker and Docker-Compose

General: https://docs.docker.com/engine/install/

Raspberry Pi: https://phoenixnap.com/kb/docker-on-raspberry-pi

Step 2. Install Docker-Compose

Acknowledgments

The inspiration for this project was a video of Todd Parker in which he explained how to open up a Ikea SYMFONISK speaker and hook up the woofer output to a subwoofer. Video

I hooked my SYMFONISK up to my Sonos Beam, which works great, but the volume of the subwoofer is always out of sync when using the tv remote.

This program is written using the SoCo Python library

Open container terminal

docker exec -it sonosvolumesync_sonos_container_1 /bin/zsh

Open container log

bash openlog.sh
