Wiring a Control with One Black, One Red, One Blue, One White Wire (3-Way with a Pico Remote)

Great tutorial!!

After following these directions for the dimmer switch, the light didn’t come on. Then i find out from an electrician that the directions are wrong. The different colored screw is the grounded wire, which attaches to the green wire on the lutron switch

why would you cap a bare unused copper ground? Whats the purpose?

I followed these instructions but once I cap location 2, my lights will stay in the on position and I cannot turn off with location 1. Any advice?

The instructions in this video say "connect the tagged wire to the black wire on the dimmer" However the PDF instructions for the PD-5ANS/PD-6ANS say to tagged wire to the RED wire.
Which one is right?

I understand that the blue wire isn't needed here, but I'm curious, what purpose does the blue wire serve?

Great video.

This video shows the marked wire attaching to the black lead on the Lutron device. The 3 way wiring instructions on the Lutron website show the marked wire attached to the red wire. Which one is correct? I debugged my install for an hour based on the instructions before I found this video, followed it instead and successfully completed my install.

Is it not bugging anyone else that he installed the second switch plate crooked???

Does it matter in which location you hard wire the switch ex. Like the leg end or where the power is supplied in the three way

Is it necessary to install two switches or will the one work with a decora switch?
