This is the sketch i'm using for controlling a number of sockets around the house.
/* RF433Mhz Transmitter node:
This sketch allows On-Off-Keying (OOK) control of four 433Mhz relay outlets
which utilize the common PT2262 encoding chip for signal transmission. The sketch could
be easily expanded to include additional outlets. The sensor node consists of a nano
connected to a NRF24L01 and a 433Mhz transmitter connected to pin 3, 5V and Gnd. The
transmitter can run off of 3.3V as well.
The sketch is based on the MySensors project (http://www.mysensors.org).
