Hi there - I've been having trouble adding a PD-5ANS to a 3-way switch. The wiring to the existing mechanical switches is as follows:Switch #1: One cable in the box with three wires: black, white, and red. The black wire is attached to the common screw; white and red go to the other ones.Switch #2: Two cables in the box. One cable has two wires (we'll call that cable "A"). The other has three wires (we'll call that cable "B"). The black wire from cable A is attached to the common screw. The white and red wires from cable B are attached to the other screws. The white wire from cable A and the black wire from cable B are connected with a wire nut.The lights turn on when both switches are flipped in the same direction. If they are flipped in opposite directions (one up, one down), the lights turn off.I followed the "Advanced Installation Guide" for installing the PD-5ANS with the Pico remote. I combined the three wires in switch #1 with a wire nut and installed the Pico remote with a mounting plate; simple enough. Then, I followed the directions for installing the PD-5ANS in switch #2. Black-A (which was attached to the common screw in the mechanical switch) went to the Lutron's red cable. White-B and red-B went to the Lutron's black wire. The Lutron's white wire was added to the existing white-A/black-B wire nut. Lutron's blue and green wires were capped (no ground available). In this configuration, the PD-5ANS was unresponsive with no green light.I then watched a Lutron 3-way installation video on Youtube. .In the comments, Lutron says: "The common wire on the line voltage side of the 3-way will be going to the black wire of the dimmer. The common wire on the load side of the 3-way will be going to the red wire of the dimmer." With that information, I tried again. This time, I connected black-A to Lutron black, white-B and red-B to Lutron red, and Lutron blue and Lutron green separately capped. Still nothing.I splayed all the wires in the two boxes and used a non-contact voltage detector. To my surprise, I found that white-A was the only live/hot wire. So, it seems like my lights and switches might be wired like this:With all that said, how should I install the PD-5ANS in this configuration?Thanks for any help you can provide.
