Grouping and ungrouping
1
Open the room you want as the anchor
Whatever this room is playing is what the group will play.
2
Tap the group button
It’s in the top-right of the room page. The Group Rooms sheet lists every other room on the system with a switch.
3
Turn rooms on or off
Switch a room on to add it to this room’s group; switch it off to make it standalone again. Changes apply immediately. Tap Done when you’re finished.
Two rooms that share the same name can’t be told apart by Sonos® when grouping. If the sheet points this out, rename one of them first — press and hold the room name at the top of its page, or swipe left on it in the menu.
