Sonos Binding - Group Volume


I have a problem - maybe it is not a problem - but lets see.
I have multiple Sonos Play 1 , separated in different rooms and a Sonos Connect (connected to my AVR)

The Problem is, that at least the Connect and all other Play 1’s need different Volume Levels. e.G.: the combination Connect & AVR is much less noisy then the Play 1’s.

Is there a possibility to control the Group Volume like in the iPhone App? Here it is possible to set different Values for the Volume and change them together.

And I don’t want to change the volume on the AVR;)

Any Ideas? If I group the Volumes - of course all of them were set to a same value …


No such feature is yet implemented in the binding.
