    @Moshe-Livne just deactivate the this lines:
    //digitalWrite(MAILBOX_FRONT_PIN, HIGH);
    //digitalWrite(MAILBOX_BACK_PIN, HIGH);

    and solder two resistor from 3.3v to pin 2 and 3.

      Ok, so I found that it is the radio that draws about 7mA when I ground input pin 2, it is connected to IRQ-pin on the radio.
      @n3ro Have you connected the radio as described on the build-page? [http://www.mysensors.org/build/connect_radio](link url)

        @f1dev yes. But you don't need irq on a node :)

          I'm guessing that your repeat() function is wearing out the battery.

          By the way you can take advantage of the return of sleep( ) here:

          gw.sleep(MAILBOX_FRONT_PIN - 2, CHANGE, MAILBOX_BACK_PIN - 2, CHANGE, 0);
          

          like this (untested):

          #include <MySensor.h>
          #include <SPI.h>
          #include <readVcc.h>
          
          
          #define NODE_ID 21                      // ID of node
          #define CHILD_ID 1                      // Id of the sensor child
          
          #define MAILBOX_FRONT_PIN 2             // Arduino Digital I/O pin for button/reed switch
          #define MAILBOX_BACK_PIN 3              // Arduino Digital I/O pin for button/reed switch
          
          #define MIN_V 1900 // empty voltage (0%)
          #define MAX_V 3200 // full voltage (100%)
          
          
          MySensor gw;
          
          MyMessage msg(CHILD_ID, V_TRIPPED);
          
          boolean post = false;
          boolean lastpost = false;
          int oldBatteryPcnt;
          int repeat = 20;
          
          int trigger = -1;
          unsigned long goToSleepTime;
          
          void setup()
          {
            gw.begin(NULL, NODE_ID, false);
            pinMode(MAILBOX_FRONT_PIN, INPUT);
            pinMode(MAILBOX_BACK_PIN, INPUT);
            digitalWrite(MAILBOX_FRONT_PIN, HIGH);
            digitalWrite(MAILBOX_BACK_PIN, HIGH);
            gw.sendSketchInfo("Mailbox Alert", "1.0");
            gw.present(CHILD_ID, S_MOTION);
            Serial.println("---------- set Mailbox empty");
            msg.set(0);
          }
          
          void loop()
          {
            if (millis() - goToSleepTime > 10UL) //debounce
            {
              switch (trigger) {
                case 0:
                  post = true;
                  Serial.println("---------- New Mail");
                  break;
                case 1:

            {
              Serial.print("---------- Send Mailboxstate ");
              Serial.println(post ? "full" : "empty");
              msg.set(post);

            @n3ro Ok, thanks! Then I learned something new today.. IRQ is only needed for receiving nodes then, like repeaters and gateways, right?
            Strange though that my circuit draws so much more current than yours. I have tested different setups, different arduinos and different radios from different suppliers with same result.
            Well, at least my mailbox are mysensored now! :smiley:

              I think you need the irq only for the gw. I have a receive node without irq.

              Do you have changed fuses on your arduino?

              And remember. All this stuff is cheap China electronic.The devices can vary consume a lot of electricity.

                Nope, havent done that yet. It´s a "stock" 3v3 pro mini. Still reading up on how to do that and how to change to MYS-bootloader, curious on how OTA-update works.
                Big thanks for your respons! :smile:

                      @n3ro Brilliant! He recommends to take out the voltage regulator. it is easier (and works better) just to snip off one leg as described here http://www.mysensors.org/build/battery. I'll try his other mods.... hopefully now my nodes will last forever!!!!

                        quality project, been having a tinker with mixed results. used sketch from original post, but would it be possible to get a circuit diagram showing pull up locations??? bit of a beginner, but have had a few success with rolling out some power operated sensors , this is my first battery operated sensor...
