I have multiple sonos speakers throughout my house. I have one speaker, a Play:1, that oddly has been giving me fits lately. About 75% of the time, in the SONOS app, the speaker doesn’t show up anymore. HOWEVER, the speaker Does show up when I access my speakers via the spotify app. More so, I am able to play music on this speaker when I access it via spotify.
Unplugging and plugging back in does temporarily fix the issue, however, the speaker is really high on a shelf so requires a ladder to do so. Additionally, after a day or two, it pops back “offline” again. There are also times when the speaker may have been offline yesterday, but now today, it is showing back up. Its really weird. We have many of the exact same model Play:1 speakers throughout the house, and this is the only one giving troubles…..and oddly enough is the speaker we want to use the most.
