      @AWI thanks again!
      I am using your sketches with only one S0 Meter (the 2000pulse/kwh one).
      *One thing i just found out, that as long as the master arduino is connected to the serial port of my pc it is running fine but when its not, it does not send.I have checked the voltage at the radio and it is the same... I also do not have any display or rotary encoder, as I do the visualisation with FHEM.
      Do you know why this is the case? * -> Voltage was to low... but the secon question remains:

      Any idea to use differen pulses/kwh S0 meters? for example one 2000pulse/kwh and one 800 pulse/kwh.
      thanks in advance!

      @jeti as mentioned in a previous post..

      There are a few ways of getting it changed:

      You can keep/ leave most as it is and when you send/ or display the values divide the pulses by two and double the Watt values in the routines "LCD_local_display" and "sendPowerUpdate"

      or: make the necessary calculations when the data comes in. This is a little more complicated in routine "storeMeterJSON" but if you understand the logic (including error corrrection) should be not too hard.

      I don't have the time at this moment to do it for you...

          was not that much work :smiley:
          this is the modified master-sketch from AWI i am starting to use. The changes i made:
          -deletion of LCD and rotray part
          -deletion of accumulation part
          -modified meterType to meter800, meter1000 and meter2000 this reflects meters with 800imp/khw;1000imp/kwh;2000imp/kwh

          I am using this with only one meter (2000imp/kwh) for now and works pretty nicly second different meter type is on the way.

          As I am a beginner please be gentle with comments :-)

            Good evening,

            After a couple of weeks, again i'm busy with my arduino's, but now i have a rasberry with domoticz near my arduino, so i don't need to send it wireless.
            Is there a possibility to connect the master or slave arduino directly to my rasberry and read out the pulse meters???

              With MySensors version 1.6 (currently in development) you can connect the Arduino to the Raspberry Pi's USB port using a FTDI or CH340G. That type of connection is called a serial gateway. Before 1.6, the gateways do not support local sensors.

                So with 1.6 i can install the master software and connect my arduino master directly through usb without the rf24''s? ?

                  I am not entirely sure what a master is, but yes, I think you can.

                    I meen the master sketch like written above.

                    I'd want to build a gateway but without the wireless RF part, just connect the master arduino directly through usb to the RasberryPi and readout the measurements.

                    So in general:

                    Kwh Meters -- cable --> Slave arduino <-- serial --> Master arduino <-- USB --> RasberryPi

                      @MarkV If you don't want it to be MySensors enabled and not used the display etc. it's easier to readout the slave with the raspberry. The protocol is a simple Json and if you use a nano for the slave you can connect it with usb..

                        Last weeks i'm trying to get it to work but without luck. Could you give a manual on how to get it working with json? What should we do? And how? On my rasberry, on the arduino and in domoticz??

                          @FotoFieber To be honest .. a left over from some experiments. Just leave it out... you won't notice the difference.

                          @AWI
                          Goodmorning,
                          I've got a question, are you planning to re-write the script for the main and slave Arduino to the new MySensors 2.0 structuur?

                          I've also tryed to look on github if there's a page from you, but didn't find it...

                            @MarkV I updated the sketch for main a few months ago to development (pre-2.0). Also changed it a little for stability and removed the (complicated) JSON library The slave has no MySensors dependency.

                              Is this correct?
                              Because Domoticz doesn't change the values.
                              Also this is not the format, wich is past through in the JSON code from the slave to master duino??

                                @MarkV I updated the sketch for main a few months ago to development (pre-2.0). Also changed it a little for stability and removed the (complicated) JSON library The slave has no MySensors dependency.

                                How is it that i get the readings like above? And after a while the sensor also stops with sending data, last connection stays on that time and date.

                                I've uploaded your github sketch and done a serial readout of the measuring arduino and that one functions proberbly. No faulty low voltage errors etc.

                                  How is it that i get the readings like above? And after a while the sensor also stops with sending data, last connection stays on that time and date.

                                  I've uploaded your github sketch and done a serial readout of the measuring arduino and that one functions proberbly. No faulty low voltage errors etc.

                                  @MarkV Ok, one step at a time.. the output looks like the output of your (serial) gateway. Have you tried to switch on the "Master node" debug Serial.print() statements?

                                    It the serial output from the gateway arduino, wich i've got connected through usb.
                                    I don't have a rotaryswitch connected and yesterday evening i connected a I2c Display just to see if something changes on that.

                                    I noticed one thin, when i check the serial output, the timer on the display is reset. Further more when i stop the serial readout, the counter also stops, like if the hole thing go's into a idle or stop.

                                    I've uncommented the debug informatie wich i could find:

                                    // Handle incoming messages from the MySensors Gateway
                                    void receive(const MyMessage &message) {  // Expect few types of messages from controller, V_VAR1 for messages
                                      if (message.type==V_TEXT) {
                                        // if message comes in, update the kWH reading for meter with value since last update
                                        // Write some debug info
                                        Serial.print("Last reading for sensor: ");
                                        Serial.print(message.sensor);                
                                        Serial.print(", Message: ");
                                        Serial.println(message.getString());
                                        if (message.sensor == LCD1_CHILD ) {
                                          strcpy(lastLCD1, message.getString());  // read payload in LCD string
                                        }
                                      }
                                    }
                                    

                                    Were could i read this debug information?
                                    At this moment i got my arduino hooked up through usb to my rasberry to see if it keeps sending information.

                                    I also changed all the cables to the meters.

                                    This is how one meter looks like:
                                    0_1462289685255_upload-a785d675-02ea-45c7-9888-2616d6a5c4f4

                                    And a other one:
                                    0_1462289751196_upload-ac4e8673-e392-43ac-aeea-1be31416479a

                                    All the meters are showing also strange values on the axis.

                                    Sorry for being such a noob at this.. :-S

                                      @MarkV Hi Mark It is a rather complicated sketch, so not easy to debug remote.
                                      You need to connect the master arduino to your USB and check with the serial monitor.
                                      then add some Serial.print() statements starting form where the data is read.

                                      The piece you commented out is where the node should receive information from the controller. I expect you didn't come far enough to set that up.

                                      (as I noticed you are Dutch, we can use the chat function on the forum to get this working...please don't expect immediate answers..)
