CEC works without major problems. I can control the Vero and the receiver volume with the TV remote or alternatively with the Vero remote.
The only problem so far with CEC are the CEC kodi built in commands that don’t work out of the box, at least not all of them:
the activate source command worked right away, great.
the cec standby didn’t work until I modified the configuration following the tips from this thread: Control TV ON/Standby/Toggle using CEC Kodi built-in functions - #13 by Zissou
the cec toggle command only turn the system OFF but doesn’t work when trying to toggle back to ON.
I made some progress, by adding a cec standby command in the power menu of my skin (Titan Beta), so actually the turn off method is solved. I still haven’t figured out the turn on, I didn’t know that screen saver exit turns on receiver and TV, thanks!. I’ll play with it tonight.
