Hi!
Posted this on Reddit a few months ago (https://www.reddit.com/r/homeassistant/comments/t3xiap/control_my_onkyo_av_receiver_via_hdmicec/), but didn’t receive any answers, and still haven’t made any progress on it.
Installed GitHub - samueltardieu/homeassistant-addon-pi-cec: HomeAssistant add-on to expose Raspberry Pi HDMI CEC, and this might be 3am brain talking in defeat after a few hours of trying to get it to do what I wanted by examining logs, but how do I scan for devices? Not even sure I’ve been addressing the right device over CEC judging by the logs.
I’m using HomeAssistant’s full-fat version via a Pi with the HDMI plugged into the Onkyo.
Would love to buy someone a beer if you can help me figure this out, it sure beats buying an amplifier with ethernet unnecessarily, or mucking around with IR blasters.
