ok, so I have a couple of Rpi3b+ with AMP2's installed that I want to use to replace some Sonos Play1's in a couple of rooms. I'm trying to replicate the ease of use by having a volume and pause/play button with each speaker - so to do this I bought a couple of remotes. This works well on a single unit, but ...... both use the same id's and so pressing play (or fiddling with the volume) on one remote triggers both HiFiBerryOS units!
How can I do this? I need the buttons for the WAF (Wife Acceptance Factor) of getting rid of the Sonos speakers :(
