can not get the BH1750 to work with NodeManager



  • Hi,

    I have tried to convert (or recreate) my original mySensors 2.1.1 Sketch to a new NoteManager scetch because I love the idea behind the NodeManager (great work). I have a Sensor with the BH1750 and one DHT22 connected. With my old sketch, both sensors are working. With the new NodeManager based sketch, only the DHT22 produces a reading, the BH1750 is silent. I have tried the 1.5 and the 1.6 (beta) version (1.6 with the DHT library from the description) still nothing.

    Here are the relevant code:

    void before() {
    // setup the serial port baud rate
    Serial.begin(MY_BAUD_RATE);

    pinMode(BMPLUXPWR_PIN, OUTPUT); # to set PowerPin for BH... permanent high (works (tested via multimeter))
    digitalWrite(BMPLUXPWR_PIN, HIGH);
    delay(2000);
    /*

    • Register below your sensors
      */
      nodeManager.setSleepMinutes(10);
      nodeManager.setBatteryMin(1.8);
      nodeManager.setBatteryMin(3.2);
      nodeManager.registerSensor(SENSOR_DHT22,3);
      nodeManager.registerSensor(SENSOR_BH1750);
      nodeManager.setPowerPins(6,5,250); # Pin 5 is for the DHT Sensor

    /*

    • Register above your sensors
      */
      nodeManager.before();
      }

    all other code is unchanged.

    I can not enable debug because of too low memory 😞

    ok ok ... after disabling some default sensors (analog/digital) I have some debug output:

    REG I=1 P=3 P=6 T=0
    REG I=2 P=3 P=7 T=1
    REG I=3 P=18 P=16 T=37

    SEND D=0 I=3 C=1 T=37 S= I=0 F=0.00
    OFF P=5
    SLEEP 600s

    AWAKE
    ON P=5
    DHT I=1 T=28.70
    SEND D=0 I=1 C=1 T=0 S= I=0 F=28.70
    DHT I=2 H=nan
    BH1 I=3 L=0
    SEND D=0 I=3 C=1 T=37 S= I=0 F=0.00
    OFF P=5
    SLEEP 600s

    The Humidity reading of the BHT sensor is a little bit wired, but this is the same with my old sketch (defect?)

    Maybe someone have the right idea????

    Best regards and thanks
