I've got two Sonos 3 and a Sonos 1 set up in different rooms, with the app running on my phone and a home tablet. What's the best way to control this system? Meaning, if I want to stop the music in the bedroom, do I pause it on the app or pause it with the button on the speaker? Is one way better than the other? Same question with volume. What's the best suggested practice for this?
