Every single morning at 6AM on the dot, my Sonos Beam will turn on my LG TV and Roku. I know it’s the Sonos because I tried combinations of disconnecting devices from my network, and the problem is resolved when I disconnect it. So there’s some kind of signal being sent via wifi causing it to wake up, but I couldn’t find any such signals by monitoring traffic to the Beam. Does anyone have any ideas what might be causing this?

Do you have an alarm set?


The signal is not via WiFi, but via HDMI-CEC. You can disable HDMI-CEC support on your TV if you need to.
