Hello all,
About 3 hours ago I decided that I would finally try to program one of my 4 channel WiFi switches. Mapping the push buttons to the pins and the LED's to the pins and linking them together look about 2 hours, that's a lot longer than I expected. I then decided to make the 4 channel switch completely controllable via one of my smartwatches, here is what is look like.

Switch controlled by a smartwatch.
