I have 12 recessed lights separated into 2 sections, of 6 each currently connected to 2 dimmers. I want to replace the current dimmers with smart dimmers by Leviton. Here are the instructions and diagram from the manufacturer: https://www.homedepot.com/catalog/pdfImages/3e/3e474cd2-a567-4471-a400-3e21fd978b0b.pdf
Legend: Black - Hot/Load (dimmer 1) Red - Load (dimmer 2) Blue - Neutral Green - Ground
Smart Dimmer 1 works fine, smart dimmer 2 does not work at all, it doesn't power itself on, or switch/dim lights.
What am I doing wrong?
