HDMI-CEC Not Working


I have a question about HDMI-CEC

I have pretty much the same setup as in the example on the home-assistant website, yet my configuration is not working.
I am running hassio and have installed the CEC-Scanner add-on.
yet for some reason, it can’t find my connected devices, nor switch to a location if triggered by e.g. a script

My configuration is:
a Pi running Home Assistant is on a my LG TV’s HDMI port 1.
HDMI port 2 is attached to a LG Surround system.
Two devices are attached to the LG Surround system on HDMI ports 1 and 2.

What can be wrong?


Do you have HDMI-CEC turned on on the LG TV?

yes, its turned on
