A couple of questions, are the visor control remotes the same across Lutron systems - ie. classic radio ra, Homeworks HWI, RR2, HWQS, etc. work interchangeably? Obviously they don't use Clear Connect so they can be compatible with Homelink. Also, what technology does it use? Rolling code? Would it be possible to use a standard off the shelf remote for these and link it via the learn button?
