@Mark_W, see below for the detailed steps:
-
Open Sonos mobile app. Go to “Browse” from the bottom navigation tab, select Spotify, find the specific play lists (not just a single track), tap the Spotify playlist and hold until the menu pops.
-
Select “Add Playlist to My Sonos”. Please note that only those playlists/stations added in “My Sonos” will be shown as presets in SmartThings IDE. If you just created the Sonos playlist, there won’t be a preset created for it in ST.
-
Now go back to “My Sonos” from the bottom navigation tab, and you should be able to find this newly added playlist from Spotify.
-
This preset should be shown in SmartThings IDE like this, and you can create rule to play this preset.
