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;
}
}

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;
}
}

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!

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)
  {

serial.Print(F("temp is high! just tried to send email"));

Hello!

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

Rodrigo_Cavalheiro · October 11, 2016, 2:11pm

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?

Dave1829 · October 11, 2016, 9:27pm

Looks a bit like “flooding”?

Try changing the frequency from 5 seconds to 70 seconds…

Obvious question but have you set up email widget on the app fully?

Rodrigo_Cavalheiro · October 17, 2016, 11:17am

Hi Dave!

I made it work correctly!
Next challenge (but I don’t know how to code): if temperature stays above X degrees for more than Y minutes…

Thanks!

Dave1829 · October 17, 2016, 11:00pm

that’s great, but how did you do it?!

that is hard, it is easier to see if temp is above X every Y minutes.

otherwise you have to start using an average or median to know if the temperature STAYS above X

in my HVAC code, i use runningMedian to smooth out my temps and know that when i look at the temps every X minutes, i know that the temps is not an aberration, so it is reliable enough to use to make decisions…

or more simply you can check temp every X/5 minutes and keep a count of how many times during X the temp is higher than Y - if it is higher than Y 5 times, then trigger your warnings…???

About your suggestion:

or more simply you can check temp every X/5 minutes and keep a count of how many times during X the temp is higher than Y - if it is higher than Y 5 times, then trigger your warnings

This is exactly what I want.
I’m working on it. If you have any advice, please share it!
Thank you!

hjroh0315 · October 21, 2016, 6:22am

If the temperature is over X, trigger the temperature timer.
|20°c 10secs|
|TRIGGERED| <=Not like this.
The temperature timer should check every D secs till It exceeds Y. (Where D is a constant integer lower than Y, 2 is recommended)
If it falls before Y, stop.
If it exceeds Y, send the e-mail.
