so it looks like CEC is already enabled by default because my 4k TV can recognize the odroid c2 connected.
HomeAssistant cant control the TV without libcec. how to install it properly?
would these codes found here work? can i copy verbatim into dietpi terminal?

apt-get install cec-utils
but then
echo scan | cec-client -s -d 1

autodetect FAILED
any idea?
