did you try rebooting then after reboot try restarting the pi-cec addon. ive had a similar issue after every major update. this usually fixes it.

Hi!

I've rebooted the RPi itself many times, powecycled my TV, restarted the add-on itself, plugged the cable to a different port on my RPi but I still have these 2 warnings in my logs:

1.

Logger: pycec

EDIT:

What is more interesting is the fact if i go into the terminal I see this:

Are you trying to use cec-scanner or pi-cec? Because built in cec support was removed from ha many versions ago. You would need to be running the third party ad-on pi-cec in order to return cec functionality to your ha installation. Running cec-scanner along side pi-cec will give you errors.

Well, I went through a lot of options and decided to leave this HDMI CEC behind.

wbarber69 commented 1 year ago

Oh well it would have been nice to see what was causing your issues. I’ve been struggling with cec ever since they deprecated built in support and had to move to pi-cec. Pi-cec works just fine, but for some reason my ha server (rpi4) constantly tells my receiver to change inputs for no reason that I can tell other than pi-cec may be scanning the network from time to time.
