Homebridge is a bridge. It gets a message on 'one side,' transcodes it, and sends it out the 'other side.'
There's not much to see... certainly nothing interesting.

My Homebridge is running on a Mac Mini "server" -- but one day I did some updating and 'broke' it. I installed it on an rPi in 20 mins and used it for the rest of the time it took to find the idiot thing I had done.
