I purchased 3 Hue play bars (connected to one power plug) which were working well before I mounted the 3 play bars hue play bar to my tv (behind the TV with the mounts supplied) now the 3 lights switch on and off intermittently. The three are connected to one power plug and I have tested them with another play plug still the same on and off and to another power connection…no joy. I have disconnected 1, and 2 of the bars and the connected one/s still switch on an off I reset the hub to factory settings no difference, I uninstalled the app no difference …my other hue lights (huego and bulbs) are fine. They are behind a Sony TV PLEASE HELP its driving me insane. Im just wondering if the TV interferes with Zigbee. Anyone have ideas??
