Downgrade a Sonos product to S1

Some Sonos products must be downgraded to S1 before they can be added to an S1 system. The Sonos S1 Controller app will let you know if the product you're setting up needs to be downgraded before it can be added to your S1 system. This article will guide you through the software downgrade process.

If you aren't sure if your Sonos product can be downgraded to S1, check our compatibility article to see if it's listed under “Works with all Sonos apps.”
