Trouble with Wiz light and HTPC

I’m not sure if this is the right section to post, but I have a Wiz light set up to turn off when I press Play on my HTPC, and turn on with Pause and Play. Everything worked great when I tested it out but last night I watched a full movie for the first time. After about 20 minutes in the light turned on by itself so I hit Play again and it went off. After another 15 or 20 minutes the light came back on again. This kept happening over and over. Does anyone know what would be triggering the light out of nowhere? Here’s my settings.
