I have a 2 gang box with two switches. One switch goes to kitchen, the other to the dining area light. These are not 3-way switches. I bought Lutron Caseta Wireless dimmers for each. These switches have 2 black wires and one ground each.My wiring for these lights is not as straightforward as I'd expected. I have two Romex coming up. One has red, black, white, and bare. The other has black, white, and bare. And the two existing switches are wired together.How do I wire the Lutrons properly with this? Thanks for your help, guys.
