Blynk.logEvent not working

Need Help With My Project
1

Event is not getting generated. Please help

void loop()
{

  int sensorData = analogRead(A0); //reading the sensor on A0  
  int MyValue = map(analogRead(A0), 200, 450, 0, 40);
  Blynk.virtualWrite(V5, MyValue); //sending to Blynk

  
  if (MyValue<21)
  {
   if (temp==0)
    {
    Blynk.logEvent("wtr_lvl_low", "Water Level Low (below 20) in Water Source Location 1 - 26°18' N 89°39' E ") ; 
    Blynk.notify ("Water Level Low in Source 1");
    Blynk.virtualWrite (V0, HIGH);
    temp=1;
   }
  }

  else if (MyValue>20){
    Blynk.virtualWrite (V0, LOW);
    temp=0;
  }
    Blynk.run();
  timer.run();
 
}

How have you configured the event in the web portal?

Pete.

Yes Sir

Hey there,

First read this :
https://docs.blynk.io/en/legacy-platform/legacy-articles/keep-your-void-loop-clean

Second blynk.notify has been replaced with blynk.logevent.

Third read this :
https://docs.blynk.io/en/getting-started/events-tutorial

Sir, changed the code to

int sensorData = analogRead(A0); //reading the sensor on A0  
  int MyValue = map(analogRead(A0), 200, 450, 0, 40);
  Blynk.virtualWrite(V5, MyValue); //sending to Blynk

  
  if (MyValue<21)
  {
   if (temp==0)
    {
    Blynk.logEvent("wtr_lvl_low", "Water Level Low (below 20) in Water Source Location 1 - 26°18' N 89°39' E ") ; 
    //Blynk.notify ("Water Level Low in Source 1");
    Blynk.virtualWrite (V6, HIGH);
    temp=1;
   }
  }

  else if (MyValue>20){
    Blynk.virtualWrite (V6, LOW);
    temp=0;
  }  
}
void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
pinMode(A0,INPUT);
    
  // Setup a function to be called every second
  timer.setInterval(1000L, myTimerEvent);
  timer.setInterval(2000L, WaterSensor);
  
}


void loop()
{
 
  Blynk.run();
  timer.run();
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!
}

Still not working. Please help.

Data is coming properly, and V6 is also toggling, but event not being generated.

Where are you looking for these events?

Pete.

Timeline, as well as mail

Please post screenshot of your timeline.

11

Do you see V6 go to high?
temp is not defined in your code, also there is no first temp = 0 before the first if.

12

V6 is going HIGH, temp is defined before this section

Upon trying generation of event through link, it is showing this message everyday:

{“error”:{“message”:“You have too many log events for a device.”}}

But, it should reset everyday, right? Please help

15

Yes. It should reset every day.

16

But, its showing same everyday :frowning:

Need help to resolve it.

17

Sure. Investigating.

18

I now see 3 events in your timeline. Does it work now? Have you changed your code or something?

19

Is it OK to put all that code in the loop? blynk.virtualwrite etc?

20

yes, it is working now. Thanks
