I keep getting an audible "Power failure" intermittently in the user interface and 2 red lines through Powerlinc in the bottom left hand corner. I am also having trouble adding new devices, which are "not responding". Some times, though occasionally, timers fail to respond, and lights don't turn on and off, but most of the time continue to work fine, probably 90% of the time.
Does all this mean the powerlinc modem has failed and needs to be replaced, or could there be some other issue
