I am pleased to announce a huge update to my Alexa skill for Sonos, "My Speaker". It allows you to do many things that the standard Sonos skill does not, such as playing your local Library, or Favorites, or Playlists, or services including Apple Music. It also allows access to normal Sonos groups (you can add and remove speakers by voice), and play things Everywhere.
it does require a companion app (now available for iOS as well as Windows), and is only compatible with US Amazon accounts (not my fault).
Setup is simple: no need to change the names of any speakers or anything, just say "Alexa, open My Speaker", login using your Sonos account, then install and run the companion app.
If you have any support questions please PM or email me, this forum is NOT the place for support questions for my skill.
