Bought the Beam when it was released and had some issues setting it up as the app would not recognize the anynet/ARC from the Samsung TV (MU7000F). After sorting that out I learned that the TV would lose connection with the Beam if I turned the set top box off (Fios). That meant going through the whole setup each time (unplug TV and power back on to get it to find HDMI connection). I found out that if I leave the set top box on but just turn the TV off, no issues with the beam disconnecting. Now the TV turns on at random times day and night. I'm assuming the Beam is doing this as it never happened before.
