I try to be able to control the volume of my Balenasound independently.
I have (for the moment) 2 Balenasound RPI3+, all work perfectly, but i want to control the volume +/- by equipment.
Currently when I send music to one of the equipment I control by spotify, but I cannot lower the sound level of a room.
I tried by snapcast.net but I only see the server being published, I cannot control the children (player)
Is there an app or a way to control each player?
Thx for help
