Set a sleep timer on any room from your Mac. The speaker counts down by itself and stops the music, even if your Mac goes to sleep first.
Doppelgänger hands the timer to your Sonos speaker, and the speaker does the counting. You can close Doppelgänger or let your Mac sleep, and the music still stops on time. If the room is grouped, the timer stops the whole group.

Starting a sleep timer needs a licence after the trial.
