hi, please, I would like help with this project.
the variable “Avvio” changes state correctly at the set time, but the “rele” and the LED widget remain off.
while if the code below is inserted, the relay is activated. but I would like to set two conditions for this to happen, time and temperature, with the first as a priority

BLYNK_WRITE(V1) {   // Scheduler #1 Time Input widget  
  TimeInputParam t(param);
  unsigned int nowseconds = ((hour() * 3600) + (minute() * 60) + second());
  unsigned int startseconds = (t.getStartHour() * 3600) + (t.getStartMinute() * 60);  
  unsigned int stopseconds = (t.getStopHour() * 3600) + (t.getStopMinute() * 60);
  int dayadjustment = -1;  
  if(weekday() == 1){
    dayadjustment = 6; // needed for Sunday Time library is day 1 and Blynk is day 7
  }
  if(t.isWeekdaySelected((weekday() + dayadjustment))){ //Time library starts week on Sunday, Blynk on Monday  
    //Schedule is ACTIVE today 
    if(nowseconds >= startseconds - 31 && nowseconds <= startseconds + 31 ){    // 62s on 60s timer ensures 1 trigger command is sent
     led1.on();  // turn on virtual LED
      digitalWrite(rele,HIGH);
      
      
      Serial.println("Schedule 1 started");
    }                  
    if(nowseconds >= stopseconds - 31 && nowseconds <= stopseconds + 31 ){   // 62s on 60s timer ensures 1 trigger command is sent
     led1.off();   // turn OFF virtual LED
      digitalWrite(rele,LOW);
               
      Serial.println("Schedule 1 finished");

@gionni can you post the QR code image for a clone of the project.

@gionni just running your project here.

You can’t have the sync in the loop, move it to BLYNK_CONNECTED()

V1 scheduler is working fine after tweaking your sketch.

I will check V2 now.

6

In your first sketch you have //led1.on(); so that will never turn on the LED.

Are your relays triggered HIGH or LOW, the vast majority are LOW.

You have D1 defined twice in your sketch, comment out the first one.

I don’t like to see “D” in sketches so my version has the real GPIO references.

Are you connecting your relay to the correct pin.

Also I don’t like to see "bad " pins being used when there are still “good” pins available.

thanks for now. I’m leaving for week end.ti update in the next days

Ok, when you get back to your code the other things to look at are:

I don’t like to see single letter variables like h and t especially when t is already used as a Time Input variable.

Unless you are really short of memory then h and t should be declared globally.

With the code you have at the moment schedule 2 will only trigger the LED and relay when schedule 1 is also active (Avvio == 1).

I think you have schedule 2 code in the OFF section and you probably need it in the ON section. Maybe led1.on referred to in schedule 2 should be led2.on and you don’t have an off in the else. It depends what you are trying to do and if your relays are active HIGH or LOW etc.

hello.o took note of your advice, more or studied a bit, and I think I have achieved a fair result.now or in mind some change …
however it now works.
thanks again

Ciao Gionni sono molto interessato al tuo progetto. Ho copiato tutto ma ci sono diversi problemi. Sei riuscito a fare funzionare tutto per bene. Gradirei tanto sapere come. Grazie

13

What issue do you have?
The first thing I will do is to stage timers because at 10 seconds , they all work :wink:

timer.setInterval(10000L, sendSensor); 
timer.setInterval(1000L, activetoday);
timer.setInterval(1000L, clockDisplay); 
timer.setInterval(5000L, reconnectBlynk);
14

its ok

Il bottone manuale non funziona e non funziona il led relè on
