Thank you in advance for any help. I am first time poster so hopefully this message is in the right place and makes sense.
I am trying to remove an old Leviton Decora system and replace it with new Lutron Caseta wireless switches. I have replaced a number of other standard GFCI switches in the house with no problems, but having a little trouble figuring out the wiring for a few outside lights that are controlled by an old Decora setup.
Specifically, there are three DHC 16400 wall controllers (each with four switches) which are located in three different locations throughout our house (front door, back door, and master bedroom). Three of the switches control low voltage landscaping lighting (though two transformers) and are wired into the breaker box after passing through Leviton controller switches (Cat. 6291). These control outside lights on our patio, front porch, and an uplight on a tree - all labeled in the picture below. I think one of the switches also controls a line-voltage up-light (with it's own built in transformer), but have not been able to test that since it is broken.
The fourth switch controls flood lights that are mounted around the outside of the house and runs through a different set of switches in the attic mounted together with some other wires that also seem to control our attic lights (see picture below).
The Decora systems has started to fail and I want to replace it with a Lutron system so I can control everything through one interface (since my other smart switches are all Lutron). I ultimately would love to control all of these lights this way, but in the short-term I would be happy just removing the flood lights and operating them separately.
I can't seem to figure out (or find a manual) on exactly how the old Decora system works / is able to control multiple lights with only one line and one load wire.
Would love any advice on others who have replaced this system or have more electrical knowledge than I do.
Thanks so much!
