I have 2 sonos units and a large radio Ra2 system (97 devices) integrated into control 4. My dealer has had an impossible time making the motion sensors work with contol4. Recently my sonos units went off line and the system has worked perfectly. I am using the extra vegetables sonos driver. Anyone else with this issue? I am scared to reintegrate the sonos units if that is going to mess up my using the motion sensors to trigger events.
