I was installing a few HS200 switches for the first time. I tried to install two of them in the same box that has only one power source. I thought I followed the same wiring that I had for the two old switches that these are replacing, but I can't get them to work independently. I then tried a multitude of wiring methods, I could not get them to work correctly. So, can two HS200s be wired in the same box. If yes, could you refer me to a simple diagram? Note: I used web diagrams when I started having problems, but I still could not get them to work correctly.   Thanks
