I’ve just notice since 30 minutes ago I can not login to Blynk Cloud Server

Any chance?

Jordan_Heinz · October 6, 2016, 2:12am

Hard to tell if I’m fighting some problem tonight as well or if I have code issues… Just sits there connecting to blynk-cloud.com over & over.

Jamin · October 6, 2016, 2:23am

Simple fix, remove Blynk.email() from the loop().

The issue you ask yourself? Well when if (tempCong >= -8) is TRUE, then it will loop the Blynk.email function hundreds of times and you will be disconnected from the cloud server due to flooding.

Also put Blynk.run() first in the loop and remove the silly delay(100000); because that will also cause a disconnect.
Avoid using delays completely.

Rodrigo_Cavalheiro · October 6, 2016, 1:45pm

Hey Jamin! Thanks for answering.

I need to monitor the fridge constantly. If I put the if-clause out of the loop, I’ll be taking the reads only one time! Right?

Thanks.

hjroh0315 · October 6, 2016, 1:50pm

You can use SimpleTimer library to query the data once in 30 secs.
Also you can use a Graph widget for an alternative.

hjroh0315 · October 6, 2016, 2:05pm

I saw that you run the sendTemps in 1 sec interval. Put the email part in there.

Jamin · October 6, 2016, 8:43pm

yup put it behind a timer at 500ms, then make sure you set a boolean after you send the email so that it only sends once.

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

void monitorFridge(){
  if (tempCong >= -8 && !sentNotice) 
    {
      //Blynk.notify("Temperatura alta!");
      Blynk.email("rodrigo.cavalheiro@gmail.com", "Alerta de temperatura", "Câmara de congelados acima de -8C!");
     sentNotice= 1; // mark it sent so it doesnt loop and flood
     } else if(tempCong != -8) {
   sentNotice= 0;
}
}

Rodrigo_Cavalheiro · October 6, 2016, 11:55pm

Jamin, that was awesome!

I can read the temperatures in the app but I don’t receive the emails.
Please notice that there are 2 temp sensors.
Both boolean variables were declared correctly.

My code:

    void setup()
    {
  // Set console baud rate
  Serial.begin(9600);
  delay(10);
  // Set ESP8266 baud rate
  EspSerial.begin(ESP8266_BAUD);
  delay(10);

  Blynk.begin(auth, wifi, ssid, pass);
  DS18B20.begin();
  DS18B20B.begin();

  timer.setInterval(5000L, sendTemps); // Temperature sensor polling interval (5000L = 5 seconds)
  
}

void sendTemps()
{
  DS18B20.requestTemperatures(); // Polls the sensors
  DS18B20B.requestTemperatures();

  tempCong = DS18B20.getTempCByIndex(0); // Gets first probe on wire in lieu of by address
  tempResf = DS18B20B.getTempCByIndex(0);

  Blynk.virtualWrite(4, tempCong);
  Blynk.virtualWrite(5, tempResf);
}

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

void monitorFridge(){
  if (tempCong >= -8 && !sentNotice1) 
    {
      //Blynk.notify("Temperatura alta!");
      Blynk.email("rodrigo.cavalheiro@gmail.com", "Alerta de temperatura", "Câmara de congelados acima de -8C!");
     sentNotice1= 1; // mark it sent so it doesnt loop and flood
     } else if(tempCong < -8) {
   sentNotice1= 0;
}
  if (tempResf >= 11 && !sentNotice2) 
    {
      //Blynk.notify("Temperatura alta!");
      Blynk.email("rodrigo.cavalheiro@gmail.com", "Alerta de temperatura", "Câmara de congelados acima de 11C!");
     sentNotice2= 1; // mark it sent so it doesnt loop and flood
     } else if(tempResf < 11 ) {
   sentNotice2= 0;
}
}

Jamin · October 7, 2016, 12:02am

Hey firstly just make sure you format your code correctly.
do this:

```
code
```

also you forgot to set up a timer for monitorFridge().

timerFridge = timer.setInterval(500L, monitorFridge);

Rodrigo_Cavalheiro · October 7, 2016, 1:55am

Jamin, last question: I can’t receive the emails.

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

void monitorFridge(){
  if (tempCong >= -8 && !sentNotice1) 
    {
      //Blynk.notify("Temperatura alta!");
     Blynk.email("rodrigo.cavalheiro@gmail.com", "Congelados > Alerta de temperatura", "Câmara de congelados acima de -8C!");
     sentNotice1= 1; // mark it sent so it doesnt loop and flood
     } else if(tempCong < -8) {
     sentNotice1= 0;
}
  if (tempResf >= 11 && !sentNotice2) 
    {
      //Blynk.notify("Temperatura alta!");
     Blynk.email("rodrigo.cavalheiro@gmail.com", "Refrigerados > Alerta de temperatura", "Câmara de refrigerados acima de 11C!");
     sentNotice2= 1; // mark it sent so it doesnt loop and flood
     } else if(tempResf < 11 ) {
     sentNotice2= 0;
}
}

Also, I put a timerFridge.setInterval(5000L, monitorFridge); in void setup()

Thanks!

where is sentnotice declared?

you should add in some serial prints to see if/where the code is not working…

Rodrigo_Cavalheiro · October 10, 2016, 11:31pm

No success at all… No email sent. Do you guys have any idea?

Dave1829 · October 10, 2016, 11:40pm

use serial prints to see where it is failing.

  if (tempCong &gt;= -8 && !sentNotice1)
  {

Hello!

I changed the code to include serial prints, tried to change the email but email still not working.

Even when I try to send a “Success login” notification or email on void setup() it completely ignores the command.
Do I have to call any library for notifications or email?
