I am running MagicMirror on a Raspberry Pi connected to a TV via HDMI; using HDMI-CEC so the screen can turn off when idle. It works but the moment MagicMirror updates a module (like weather or calendar), the TV wakes up unexpectedly; even though no user interaction happens & the Pi itself is idle.

I have already disabled mouse movement; set the screensaver & tested various xset & vcgencmd commands but the HDMI signal still seems to “ping” the TV during certain background activities.

I want the TV to stay off unless there’s real user input ideally keeping background updates silent. Checked https://forum.magicmirror.builders/topic/15153/wake-up-hibernate-display- Splunk online training guide related to this and found helpful.

Has anyone managed to prevent MagicMirror from waking the HDMI display due to CEC/HDMI activity alone? Would love advice on whether it’s a module issue; electron/browser behavior, or if there’s a Pi/CEC flag to block this sort of unintended wake-up.

Thak you !!
