Thanks for the help. I started logging with DEBUG, but I wasn’t seeing anything that looked pertinent (other than the hue emulator starting). I switched it over to trace and see this as I try to pair:

192.168.1.125 is the echo, 192.168.1.200 is the server, and I’m also seeing it from 192.168.1.208 which is my Hue bridge. Same network, same subnet, only one network interface, tagging like this - [“homekit:Switch”]
