i am using DietPi for the odroid c2.installation of HA was super easy! but i dont think HDMI cec was included.
i ran this manually in terminal:
sudo apt-get install cec-utils
installation had no errors.
i test it afterward:
echo scan | cec-client -s -d 1
and getting error of:
autodetect FAILED
from HA’s cec instruction page, i dont see this directory
/usr/local/lib/python*/dist-packages/cec
please help
