I have two symfonisk remote that I want to use for my living room and my kitchen.
Idea is: Each controls its entity. That part is easy.
But, I also want it to control all grouped entities, if the speaker is currently group with something else.
E.g., if the kitchen is currently grouped with the living room then I want the kitchen control to control sonos devices in kitchen and living room simultanously (and vice versa).
How do I do this?
