I have a handful of virtual switches and I set their Network Device ID by taking my last Z-Wave devices ID and incrementing it by 1. Just recently I was trying to pair a few new GE outdoor outlets (Zwave) and they would never pair. I finally realized that they were trying to use the same ID as one of my virtual switches. I changed all the virtual switches ID’s to start with 100 then the new devices paired right away.
So apparently the new devices were not able to see the virtual switches and know the ID was already taken?
Just figured I would post this in case it helps someone else out
