Control HEOS by Denon from your flic
Control HEOS speakers by Denon, so you can choose where the music will play.

Perhaps just a button press to play current Playlist in a certain room.
Start a specific source like Spotify or a specific radio station.
To be able to switch from Spotify to optical input, or volume control
Great Idea plus volume control??
Great idea , is an open system!
