Hi to all. Hope someone can help here.I bought a home with (2) existing Sivoia shades, one works (call it A) - the other does not (call it B). I proved the wiring by moving the operating shade (A) to replace the one that didn't (B) - and it worked by the keypad. So the cable to B works and I assumed it was the motor and bought a replacement (call it C) but this one does not work either! I tried both B and C on the cable feeding A that I know does work - and nope, neither works. They flash blue, green, red but do not respond to the keypad. Also, I went through the trouble shooting guide on the Lutron site but nothing wrong with the wiring.I can operate both with the limit switch adjustment buttons so the motors are not seized or anything.Did I buy a bum motor? It's just odd having the same problem twice in a row.Any ideas? - thanks very much.
