I’m putting my home assistant server inside a vintage console stereo cabinet. The problem is that, of course, I can’t see any status lights when it’s in there, so I’m trying to connect some addressable LEDs (places behind the speaker grills) that can show me power, boot status, drive activity, network connectivity and activity, etc.
I’ve been trying to do this with an ESPC6 board and had some success, but one of the primary things I’d like to be able to see if the power and boot status. It was suggested that I might be able to send boot status messages (specifically, power on, Linux booting, Home Assistant starting, fully started) over a serial connection to my C6, but I’m not sure how to go about that and could use a little guidance.
