Flashback: Radio Shack Plug'n Power

@Leo was talking on the radio show today about powerline networking, and it caused me to have a flashback to my youth of using Radio Shack Plug’n Power remote switches. We’re all used to IoT these days being WiFi driven, but there used to be fun days when you needed to make sure your switch codes didn’t accidentally line up with your neighbour’s or else they could accidentally operate your device(s).
