    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 :)

      @n3ro

      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:
              post = false;
              Serial.println("---------- Mailbox emptied"); 
              break;
            default:
              Serial.println("---------- I just woke up");
          }
        }
        trigger = -1;
        if (post != lastpost)
        {
          Serial.print("---------- Send Mailboxstate ");
          Serial.println(post ? "full" : "empty");
          msg.set(post);
          lastpost = post;
          sendBattery();
        }
        // Sleep until something happens with the sensor
        goToSleepTime = millis();
        trigger = gw.sleep(MAILBOX_FRONT_PIN - 2, CHANGE, MAILBOX_BACK_PIN - 2, CHANGE, 0);
      }
      
      void sendBattery() // Measure battery
      {
        int batteryPcnt = min(map(readVcc(), MIN_V, MAX_V, 0, 100), 100);
        if (batteryPcnt != oldBatteryPcnt) 
        {
          gw.sendBatteryLevel(batteryPcnt); // Send battery percentage
          oldBatteryPcnt = batteryPcnt;
        }
        Serial.print("---------- Battery: ");
        Serial.println(batteryPcnt);
      }

      @BulldogLowell could you please explain your changes? I don't understand everything of this :sweat:

        @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...

                            Hello,
                            Does this code still work?
                            Thank you
