Controlling appliances and lamps for very cheap
by av on Feb.17, 2016, under Projects
At the Hacklab, to save power, we needed a way to turn off devices when nobody was at the Lab. Rather than buy expensive Insteon or Z-Wave modules, Hacklab member Av (that’s me!) reverse-engineered the radio protocol on these super cheap ($8 each) controllable outlet modules.
For a total cost of $47, you can now control 5 or more outlets via Wifi. All that’s needed is an ESP8266 and a 433Mhz transmitter module. No soldering or electronics is required, it’s just three wires!
Check out the rest of the project with source code on Av’s Site.

Have you tried using the rc-switch library to figure out the codes (instead of a logic analyzer)? I’m interested in doing the same thing, but for a 315 Mhz outlet/remote combo.

Hey wow, this looks like exactly what I did by hand. Might have made it easier, but certainly not more fun. :) Thanks for the tip!
