I use the Sonos Connect, and have tried controlling it with SmartThings with poor results.
My SmartThings system recognizes the Sonos player, and I can connect and control it initially just fine, however if I try to re-start Sonos after it’s been paused for a great amount of time (8+ hours), nothing happens, and the Sonos/SmartThings connection seems to be broken. I can uninstall and reinstall the app, and it works fine again.
One note: I have noticed that when I open my Sonos app on my iPhone (outside of SmartThings) it usually takes a few seconds to pull up the system. I wonder if somehow it is going into a “sleep” mode?
Has anyone experienced this same thing? Any suggestions?
