Hi there, I have a two switch setup, they were daisy chained, should have taken a pic before disconnecting but didn't. They were independent and didn't rely on one being on for the other to work. Now that I've replaced one with a WeMo switch, daisy chained how I thought it was originally, it's now relying on the other switch to be on to work. One switch has two black wires. The other switch has 3 black wires. What am I missing to ensure these can act independently without the other being on as was the original daisy chain setup? THANK YOU!
