"We are pleased to announce that Sonos is now officially supported by SmartThings! Together, Sonos and SmartThings are launching a new and improved integration that includes audio notification improvements and local execution for a faster and more stable connection.
We have identified that you are currently using the legacy Sonos integration, which will soon be deprecated.
In order to prevent any impact to your current setup, manually update your Sonos speakers to the new integration with these steps:
- Remove the speakers and reconnect them using the new SmartThings app
- Update any existing SmartApps or Automations that control your Sonos speakers
- Sign in to graph.api.smartthings.com, select Locations > Devices > Sonos speaker > Edit > Type dropdown list > LAN Sonos Player Websocket > Update
If you do not take action by October 17th, your Sonos integration will be automatically updated. Any SmartApps or Automations that have not been updated may no longer continue operating correctly.
Contact us on support.smartthings.com if you have any questions or need assistance updating your speakers.
