    Do you have a standalone relay, or a arduino relay board, like this picture?
    http://www.mysensors.org/relay/relayModule.png

    The board contains a transistor. Some boards also have a 'hi-low' switch, if yours have it, you may try to play with it.

    The arduino output is max of 40ma and will eventually burn or not operate correctly if connected directly to a relay. You must have a transistor in between.

    Make sure you relay board contains at least this circuit: http://www.electroschematics.com/8975/arduino-control-relay/

    @rvendrame My relay is more like this http://www.elecdesignworks.com/images/stories/virtuemart/product/img_62112.jpg

    Thank you for your reference.
    It has a transistor. I hope it's ok to use. I have tested it by following an instructable.

      @rvendrame You know what. I'm really thankful for you help and I'm really sorry for dragging you with me. I can turn the light on now. I just have to print "2;1;1;1;2;0;" instead of "2;1;1;1;2;1".

      I will check if I will encounter any problem because of my relay module.
      Again, thank you so much for your help. And I'm really sorry.

        Just swap the 0 & 1 here:

        #define RELAY_ON 1  // GPIO value to write to turn on attached relay
        #define RELAY_OFF 0 // GPIO value to write to turn off attached relay
        

        and it will obey as you expect. Some relays boards have inverted input (Zero/GND is ON and VCC is OFF) ;-)

        I'm glad it worked.

            Is there a way to receive only the last state of the sensors/actuators in the serial?

            instead of:

            0;0;3;0;9;read: 2-2-0 s=1,c=1,t=2,pt=2,l=2:1
            0;0;3;0;9;send: 0-0-2-2 s=1,c=1,t=2,pt=2,l=2,st=ok:1
            2;1;1;0;2;1
            

            it only print the "2;1;1;0;2;1" on the serial

              I placed if statement in serial function inside MyGateway.cpp
              where 0 is the gateway address

              void MyGateway::serial(MyMessage &msg) {
                if (msg.sender != 0); serial(PSTR("%d;%d;%d;%d;%d;%s\n"),msg.sender, msg.sensor, mGetCommand(msg), mGetAck(msg), msg.type, msg.getString(convBuf));
              }
              

              Still it doesnt work.

              Heres the format:

                  msg.sender = GATEWAY_ADDRESS;
              	msg.destination = destination;
              	msg.sensor = sensor;
              	msg.type = type;
              	mSetCommand(msg,command);
              	mSetRequestAck(msg,ack?1:0);
              	mSetAck(msg,false);
              	if (command == C_STREAM)
              		msg.set(bvalue, blen);
              	else
              		msg.set(value);

                if (msg.sender != 0); serial(PSTR("%d;%d;%d;%d;%d;%s\n"),msg.sender, msg.sensor, mGetCommand(msg), mGetAck(msg), msg.type, msg.getString(convBuf));

                Note the ; after the 0) which should not belong there..

                    Should I post my new question on another board?

                      The gateway itself doesn't buffer anything. It just forwards the data from your sensors.

                          turn off DEBUG in MyConfig.h (by commenting it out) before comping you gateway sketch to get rid of debug messages.

                            @hek Thank you! I will try it as soon as I go home. Can you tell me what is the expected output from the gateway if I use static id 2 for a relayActuator that I turned on?

                            will it be just "2;1;1;0;2;1" or will "2;255;x;x;x;x" appear? only the read/send data is hidden

                              Is it ok to have two gateways?
