This app is easy to use but getting a smart switch (HS200) to connect when first installed is a exercise in patience. It litterly took me hours to connect it. I had to put a spare router BESIDE my HS200 switch with it hanging out the wall to get it to finally connect. I did reverse the two line wires which are not identified as line and load and coincidentally it seemed to connect. Once connected to the app it works flawlessly. There should be a way to connect new devices manually
