Title says it all. I have posted this over in the old community Wiz thread, but figured I would link it here since it's built-in now.
Long story short, I am not seeing Wiz discovery packets on the network, and of course no devices are discovered. When I do the same discovery by restarting the Homebridge Wiz Lan plugin, I see everything - the UDP broadcast on port 38899, the responses from all of the Wiz bulbs, and the registration to Homebridge plugin.
