Sonos2mqtt is my pet project for years. It allows you to control your Sonos speakers through a mqtt server. This pub/sub mechanism is perfect in a smarthome environment. There is an event and you want to ack on in.
This project started because I had no way to control my Sonos speakers without the Sonos application (which kinda sucks). And now years later it’s downloaded 335k times from Dockerhub
