      this is my sketch
      i use MS 1.5.1

       * The MySensors Arduino library handles the wireless radio link and protocol
       * between your home built sensors/actuators and HA controller of choice.
       * The sensors forms a self healing radio network with optional repeaters. Each
       * repeater and gateway builds a routing tables in EEPROM which keeps track of the
       * network topology allowing messages to be routed to nodes.

       * REVISION HISTORY
       * Version 1.0 - Henrik EKblad
       * 
       * DESCRIPTION
       * This sketch provides an example how to implement a distance sensor using HC-SR04 
       * Use this sensor to measure KWH and Watt of your house meeter
       * You need to set the correct pulsefactor of your meeter (blinks per KWH).
       * The sensor starts by fetching current KWH value from gateway.
       * Reports both KWH and Watt back to gateway.
       *
       * Unfortunately millis() won't increment when the Arduino is in 
       * sleepmode. So we cannot make this sensor sleep if we also want 
       * to calculate/report watt-number.

          here is my serial output. and remains like this.
          i have found your sketch but can not seem to get it to work to gw 2.0

              can you please print your code?

              I am not so good to read the Message structure but it look like it present temperature and other stuff

                Ah the gateway works fine with other sensors
                The code for the pulse power meter is the one in the example

                  Yes you do, look at the last line and you will see it.

                    @asgardro

                    change SEND_FREQUENCY to 5000, upload to Arduino, when you see Received from GW, trig Digital Input 3 and after 5 seconds it should send data to DZ again

                        don't forget to use CODE function when posting code.

                        If you don't see any reaction when you trig Digital 3 i don't know what can be the problem,

                        Have you tried another Arduino?

                          change bool pcReceived to false

                            ooops sorry about that... just found the function lol
                            the sensor inits itself once and then doesn't do anything/ i don't know through what miracle i got the pulse count.
                            will try another arduino... i do not think it is a radio problem..
                            thanks for your help

                              changed it to false.
                              put it true before to try to force the sensor sending independent of the count.. if i am correct
                              still the same outcome... will try tomorrow diffrent hardware
                              anyway, thanks a lot for the help

                                Yes it will but it will only send 0 to VAR in DZ so it will be a loop of same value.
                                Maybe that's why it never sends again.
                                Try now to trig digital 3

                                  sorry for the next noob question but what do you mean by trigginh the pin 3? simulating the sensor? if yes i done that.. i have a led blinking

                                       * The MySensors Arduino library handles the wireless radio link and protocol
                                       * between your home built sensors/actuators and HA controller of choice.
                                       * The sensors forms a self healing radio network with optional repeaters. Each
                                       * repeater and gateway builds a routing tables in EEPROM which keeps track of the
                                       * network topology allowing messages to be routed to nodes.

                                       * DESCRIPTION
                                       * This sketch provides an example how to implement a distance sensor using HC-SR04 
                                       * Use this sensor to measure KWH and Watt of your house meeter
                                       * You need to set the correct pulsefactor of your meeter (blinks per KWH).
                                       * The sensor starts by fetching current KWH value from gateway.
                                       * Reports both KWH and Watt back to gateway.
                                       *
                                       * Unfortunately millis() won't increment when the Arduino is in 
                                       * sleepmode. So we cannot make this sensor sleep if we also want 
                                       * to calculate/report watt-number.

                                          Do you mean LM393?

                                          Can you put a flash light in front of the sensor so trigger it. You shall now see some text in serial monitor
