Sonos can support many third party smart home environments by supporting the Wyoming Protocol. This would allow Sonos products to act as the microphone/speaker for wake words and more for the most popular open source smart home ecosystem: Home Assistant. Other smart home ecosystems could also then add support for Sonos.

There are not currently many good wifi connected speaker/microphones and Sonos would be de-facto the best in class product in this area. I imagine many people looking to automate their homes would purchase your products to use as their home assistant interfaces as there seems like only 1 other alternative available at the moment: ESP32-S3-BOX  (which is not very good)

After a bit of research, Wyoming is the protocol by which text-to-speach and speach-to-text components communicate with each other. Probably the sonos device needs a way to be in a low power mode except the microphone is enabled, and it exposes the audio from the microphone to a network port. It also needs some network port and signal to wake the device and receive sounds to play like activation noises and synthesized speech responses.

I assume Sonos devices already have these sorts of things since it supports it’s own voice assistant, alexa, (and previously google assistant). It should be trivial to open this up to Home Assistant.


I completely agree—this feature would be incredibly useful for many users. Considering the growing demand for 'local intelligence,' it could breathe new life into the Sonos ecosystem! Otherwise, someone might eventually find a way to hack it, but an officially supported version from the company would be far more appreciated.
