River is a big fan of home automation. After moving into a new house, he wanted to assimilate two wirelessly controlled ceiling fan lights into his home automation system. The problem was this: although the fans were wireless, their frequency and protocol were incompatible with the home automation system.
This is an interesting account of how he firstly used a SDR to find out the fans wireless remote signal frequency, decoding that signal, and then how he went about getting the GPIO pins to be able to transmit the same signals to control the fans.
