Integrate 315MHz RF Outlet with RPi and OpenHAB

After wiring you can use RCSwitch to send the string "101010101001101101100100" on 315MHz and get it to turn on or off. It's the same command for both since it's a single button switch.

1. Wire up the transmitter
2. Follow steps to Download and Install WiringPi
   https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/

1. Git clone https://github.com/r10r/rcswitch-pi
2. Edit send.cpp and replace it with this code
   
   

   #include "RCSwitch.h"
   #include <stdlib.h>
   #include <stdio.h>
   
   int main(int argc, char *argv[]) {
       /*
        output PIN is hardcoded for testing purposes
        see https://projects.drogon.net/raspberry-pi/wiringpi/pins/
        for pin mapping of the raspberry pi GPIO connector
        */
       int PIN = 0;
       char* code = argv[1];
    
       if (wiringPiSetup () == -1) return 1;
           printf("sending code[%d]\n", code);
           RCSwitch mySwitch = RCSwitch();
           mySwitch.enableTransmit(PIN);
   	mySwitch.setRepeatTransmit(2);
           mySwitch.send(code);
           return 0;
   }

3. Run "make"
4. Run ./send 101010101001
