If you’ve read other similar project posts, you’ve seen me say before that US code does not mandate any particular wire colors. People can and do use any color for anything, sometimes just because it’s the end of the day and there’s only one roll of wire left in the toolbox. So before you do anything else, you must test every segment of every circuit to see what it actually does. You can’t go by “looks like.”
You didn’t give the model numbers for your Lutron devices, but many of them do not require a neutral for the master. So you may not have one there. But the only way to know for sure is to test the circuits, and you need to know for sure before you start wiring new devices in place.
If you don’t know how to do this testing, you need to either bring in an electrician or get more education. If you live near a Home Depot, many offer classes in how to wire a light switch. They won’t usually cover network switches but at least you’ll learn how to test the lines and identify exactly what you have now . And since the GE switches are sold at Home Depot, the instructor can often help you figure that out as well.
