Well,, I couldn't resist. There is extra code in there that is not necessary on Hubitat, so I cleaned it up added some logging config and here it is. Since everything is local on Hubitat, you don't need to treat external in internal URIs any differently. It's always difficult to decide when to credit the original creators, but I figured since I basically changed every line in the file, I would just make it a generic "community" for namespace, etc.
