Blynk don’t send notifications

Need Help With My Project
1

Hello all
I have a problem in notification in Blynk.
I use Blynk 2.0 and I set notifications for first time and it work! It’s send notifications for my phone, but when I turn off the device and turn on again the notifications didn’t work! And my phone doesn’t receive any notifications, knowing that I didn’t change any things in code or events (notification settings)

This is my code:


#define BLYNK_TEMPLATE_ID ""
#define BLYNK_DEVICE_NAME "IAQM2"
#define BLYNK_PRINT Serial
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
#include <DHT.h>
#include "Adafruit_CCS811.h"

char ssid[] = "";
char pass[] = "";

#define DHTTYPE DHT11
#define DHTPIN 16
Adafruit_CCS811 ccs;
float mq135 = 36;
float mq7 = 39;
DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;

void sendSensor()
{
//DHT11  
  float h = dht.readHumidity();
  float t = dht.readTemperature(); 

  Blynk.virtualWrite(V1, t);
  Blynk.virtualWrite(V2, h);
  
  if(t == 50){
    Blynk.logEvent("temperature");
  }
  if(h > 60){
    Blynk.logEvent("humidity");
  }
  
//MQ-135
 float co2 = analogRead(mq135); 
  Blynk.virtualWrite(V3, co2);
  if(co2 > 2534){
    Blynk.logEvent("co2");
  }
  
  //MQ-7
 float co = analogRead(mq7); 
  Blynk.virtualWrite(V4, co);
  if(co > 1950){
    Blynk.logEvent("co");
  }
  
  //CCS811
    ccs.readData();
    int TVOC = ccs.getTVOC();
    Blynk.virtualWrite(V5, TVOC);
    if(TVOC > 860){
    Blynk.logEvent("voc");
  }
}


void setup()
{

  Serial.begin(9600);
  dht.begin();
  if (!ccs.begin()) {
    Serial.println("Failed to start CCS 811 sensor! Please check your wiring.");
    while (1);
  }
    
  // Wait for the sensor to be ready.
  while (!ccs.available());

  Blynk.begin("", ssid, pass); 
  timer.setInterval(1000L, sendSensor);
  
}

void loop()
{
  Blynk.run();
  timer.run(); 
}

I guess you exceeded the daily limit which is 100 events per device.

Is can send notifications again after 24 hours?

Also is there any way to increase the limit?

Yes.

Limits could be changed for the White Label clients.

I’d suggest using a flags in your sketch to avoid sending multiple notifications when the condition is met.
