I am having trouble with my harmony 880 remote and the CC-12 relay module. The connecting block flashes yellow that it is receiving the signal, but the CC12 does not want to trigger the speakers. I did email logitech service as well, waiting for response. Any ideas? -Otherwise I have been able to trigger the speakers manually by connecting CI and +12VDC on the CC-12. I really want to get this setup working before I cut into the ceiling.
