Hi
I have knocked up a python app using the new PiFaceCAD libraries in conjunction with the github SoCO Sonos library to make an infrared controller for my Sonos system.
Have you done something similar?
my motivation was when I used the Sonos Amp with my TV, there was no natural way to change the volume... having the TV remote AND the tablet with Sonos app just for volume was a pain...
it discovers all the sonos devices on your network and you can scroll through them and change the volume.
Also implemented play/pause/stop and next/previous track
I attach a screenshot of the device in a case for info...
