I've searched Lutron's site to find out what the little button is for on the back of the Smart Bridge and can't find a word on it. The bad thing is, I have one PD-6WCL connected and remember not having any issue doing it, but I don't remember exactly how I did it. I'm trying to add three more and things are not so smooth. Lights flash on the new dimmers but the APP just sits there. Does that button play a role in connecting switches?
I'm guessing that one or two of these new dimmers are beyond the range of the Bridge which is a huge shortcoming for the unit.
Thanks for any advice.
