Monitor a DIY solarpanel with ASC712 - HELP



  • Has anyone gotten a ASC712 to work with a actuator node?

    I'm trying to monitor my diy solar panel, so that I can see what it is producing(if).

    I've tried with the code below, but I can't get the node to send the readings to the gateway. I'm using a 30A ASC712 to do the readings. (Don't mind the motion sensor part).

    My last code:

    // Example sketch showing how to control physical relays. 
    // This example will remember relay state even after power failure.
    
    #include <MySensor.h>
    #include <SPI.h>
    const int analogIn = A0;
    int mVperAmp = 66; // use 100 for 20A Module and 66 for 30A Module
    int RawValue= 0;
    int ACSoffset = 2500; 
    double Voltage = 0;
    double Amps = 0;
    double Voltage_new = 0;
    double Amps_new = 0;
    
    #define RELAY_1 6  // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
    #define NUMBER_OF_RELAYS 2 // Total number of attached relays
    #define RELAY_ON 1  // GPIO value to write to turn on attached relay
    #define RELAY_OFF 0 // GPIO value to write to turn off attached relay
    
    // Motion sensor defs
    unsigned long SLEEP_TIME = 10000; // Sleep time between reports (in milliseconds)
    #define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motionsensor.  (Only 2 and 3 generates interrupt!)
    #define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
    #define CHILD_ID 3   // Id of the sensor child
    volatile int state = LOW;
    boolean lockLow = true;
    boolean lastTripped = 0;
    
    MySensor gw;
    MyMessage msgMotion(CHILD_ID, V_TRIPPED);
    MyMessage msgvolt(4, V_VOLTAGE);
    MyMessage msgcur(5, V_CURRENT);
    MyMessage msg(CHILD_ID, V_LIGHT);
    
    void setup()  
    {   
      // Initialize library and add callback for incoming messages
      gw.begin(incomingMessage, AUTO, true);
      // Send the sketch version information to the gateway and Controller
      gw.sendSketchInfo("Relay/Motion Sensor", "1.0");
    
      // Fetch relay status
      for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
        // Register all sensors to gw (they will be created as child devices)
        gw.present(sensor, S_LIGHT);
        // Then set relay pins in output mode
        pinMode(pin, OUTPUT);   
        // Set relay to last known state (using eeprom storage) 
        digitalWrite(pin, gw.loadState(sensor)?RELAY_ON:RELAY_OFF);
      }
      
      pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as  input
      // Register all sensors to gw (they will be created as child devices)
      gw.present(CHILD_ID, S_MOTION);
      // attachInterrupt(DIGITAL_INPUT_SENSOR, ON, CHANGE);
      //delay(30000);
      gw.present(4, V_VOLTAGE);
      gw.present(5, V_CURRENT);
    }
    
    
    void loop() 
    {
      // Alway process incoming messages whenever possible
      gw.process();
    
      //boolean tripped = (digitalRead(DIGITAL_INPUT_SENSOR) == HIGH);
      //  if (lastTripped != tripped ) {
    //	gw.send(msgMotion.set(tripped?"1":"0")); // Send new state
    //	lastTripped=tripped;
    //   }
      
      //Serial.print("Raw Value = " ); // shows pre-scaled value 
      //Serial.print(RawValue);
      //gw.send(msgvolt);
      //Serial.print("\t mV = "); // shows the voltage measured 
      //Serial.print(Voltage,3); // the '3' after voltage allows you to display 3 digits after decimal point
      //Serial.print("\t Amps = "); // shows the voltage measured
      for ( int i=0; i<=20; i++ ){
        RawValue += analogRead(analogIn);
        delay(50);
      }
      Voltage = (RawValue / 1023.0) * 5000; // Gets you mV
      Amps = ((Voltage - ACSoffset) / mVperAmp);
      
      //gw.send(msgcur);
      Serial.print("mV = "); // shows the voltage measured
      Serial.println(Voltage);
      //Serial.println(Amps,3); // the '3' after voltage allows you to display 3 digits after             decimal point
      //delay(2500);
    }
    void incomingMessage(const MyMessage &message) {
      // We only expect one type of message from controller. But we better check anyway.
     if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom
     gw.saveState(message.sensor, message.getBool());
     // Write some debug info
     Serial.print("Incoming change for sensor:");
     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());
     }
    }
    

    Any help would be appreciated 🙂

    PS: Att HEK - why isn't there a "insert code" button, just like the "insert link" button?

    Sorry. Haven't found any nodebb-plugin which add this in the composer. So you have to surround code with 4 backticks ```` in the meantime.

    @Hausner Serial Monitor output OK?



  • No, serial monitor was just for testing. I would like to push it to mqtt.

    I found the V_VOLTAGE and V_CURRENT, and the serial monotir showed up correctly as 38/39.

    @Hausner So the problem is with the node transmitting anything to the gateway?

    Post the radio messages from the serial monitor and hopefully someone can tell you what's going on..
