I have a dumb TV connected to a Chromebox (like a Chromebook, but no screen). Unfortunately the Chromebox doesn’t appear to support HDMI CEC, or at least I can’t find any way to do it.
I would like to use HA to turn the TV on / off on a set schedule, but I can’t tell if an HDMI CEC passthrough would let me do this.
The other HDMI port on the TV has a roku stick, which does support HDMI CEC but loses power with the TV. I’m not sure if it would be easier to just get a roku TV device (non-stick) and have that power on the TV and then switch to the other HDMI input.
Any advice or clarification would be much appreciated!
