Hi. I just installed three Caseta wireless dimmers with no issues. Now I am converting a double dimmer (Lutron S2-L Skylark) to one Caseta wireless dimmer (there were 4 ceiling lights on one pole and 2 ceiling lights on the second pole and I am bringing them together to be controlled by one Caseta wireless dimmer. There is one black, one yellow, one red and one green (ground I guess) wire. I assume the green goes to green. How do I match these wires to the two black wires on the caseta wireless?
