There is another post: Vizia rf+ VRCS2-MR 2-Button Controller that talks about the process of pairing. I have to say, I’m not sure if the steps there worked for me, I kept trying different combinations of long and short holding, resetting to factory, etc. I know at one point I had 8 or so ”remotes”. And then, magically, the switches paired properly.
When it did work, the switches reacted exactly like they do when you do a 5 second hold based on the instructions on that post, they just worked that time instead of giving me another controller. It may be that my switch may have not been reset from being paired at the factory. I wish I could give you a more informed response, but when I finally got it paired, I didn’t want to clear it out and try again…
