I use Sonos Amp for my out door patio and Spotify for my music. This is the 5th time that they have randomly turned on and at high volumes. Most of the time it seems to happen late at night. One time it was so loud that the cops came to my door! The song and play list that came on last night was a play list that a friend shared with me through Spotify.
It happened last night and I did run a diagnostic report. Any help is greatly appreciated.
