# CO/Tech power plugs: reproducing captured radio commands

> Recreates CO/Tech power-plug control with Arduino sketches that capture 24-bit commands from an original 433.92 MHz remote and transmit selected commands to paired plugs. The instructions describe the receiver connection, command capture and plug pairing.
