Timer widget work incorrectly after midnight

Need Help With My Project
22

Do you mean it in this Function? “void blynk_update()”

23

Yes.

24

Thanks. I have modified it as below:

void sensorDataSend()
{
float t = dht.readTemperature();
  Blynk.virtualWrite(V100,t);
  
  if (isnan(dht.readTemperature())) 
{ 
    Serial.println(F("Error Reading Temperature")); 
}
  else 
{
    Serial.println(F("Temp: ")); 
    Serial.print(dht.readTemperature()); 
    Serial.println(F("C")); 
    
    if(dht.readTemperature() >= 35){ 
      digitalWrite(TRELAY,HIGH); 
      Serial.print(F("T-RELAY"));
      Serial.println(F("  ON"));
    }
    else{
      digitalWrite(TRELAY,LOW);
      Serial.print(F("T-RELAY"));
      Serial.println(F("  OFF"));
    }
  }

}
void setup()
{
  Serial.begin(9600);
  Serial1.begin(9600);
  Serial2.begin(9600);
  Serial3.begin(9600);

  pinMode(SDCARD_CS, OUTPUT);
  digitalWrite(SDCARD_CS, HIGH); // Deselect the SD card
  pinMode(24, OUTPUT);
  pinMode(13, OUTPUT);
  pinMode(22, OUTPUT);
  pinMode(23, OUTPUT);
  pinMode(25, OUTPUT);
  pinMode(26, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(27, OUTPUT);
  pinMode(28, OUTPUT);
  pinMode(29, OUTPUT);
  pinMode(30, OUTPUT);
  pinMode(31, OUTPUT);
  pinMode(32, OUTPUT);
  pinMode(33, OUTPUT);
  pinMode(34, OUTPUT); pinMode(35, OUTPUT);  pinMode(36, OUTPUT);pinMode(37, OUTPUT); pinMode(38, OUTPUT); pinMode(39, OUTPUT);
  pinMode(40, OUTPUT); pinMode(41, OUTPUT);  pinMode(42, OUTPUT);pinMode(43, OUTPUT); pinMode(44, OUTPUT); pinMode(45, OUTPUT);
  pinMode(46, OUTPUT); pinMode(47, OUTPUT);  pinMode(48, OUTPUT);pinMode(49, OUTPUT); pinMode(50, OUTPUT); pinMode(51, OUTPUT);
  pinMode(52, OUTPUT); 
  pinMode(OnlineLED, OUTPUT);
  pinMode(OfflineLED, OUTPUT);
  digitalWrite(13, HIGH);
  timer.setInterval(1000L, checkTime);  
  timer.setInterval(10000L, sensorDataSend);
  timer.setInterval(1000L, blynk_update);

May I ask, would there be any problems if I have set 3 timer as shown above?

25

That’s fine, you can have up to 16

Pete.

Thanks, I will try run the device and check the Time input widget working as expected. Will try later because now had passed midnight.

27

The problem still not solve. Is there any way I can simplify the logic in “void led_mng()”?

int i;
  
  for (i=0; i<60; i++)
  {
    led_status_buf[i] = led_status[i];
    time_set_overflow = 0;
    
    if ( timer_start_set[i] != 0xFFFF && timer_stop_set[i] != 0xFFFF)
    {
      if ( timer_stop_set[i] < timer_start_set[i] ) time_set_overflow = 1;

      if ((((time_set_overflow == 0 && (rtc_sec >= timer_start_set[i]) && (rtc_sec < timer_stop_set[i])) ||
        (time_set_overflow  && ((rtc_sec >= timer_start_set[i]) || (rtc_sec < timer_stop_set[i])))) && 
        (weekday_set[i] == 0x00 || (weekday_set[i] & (0x01 << (day_of_week - 1) )))) )
        {
          led_timer_on_set[i] = 1;
        }
        else
          led_timer_on_set[i] = 0;
    }
    else
      led_timer_on_set[i] = 0;

      if ( led_timer_on_set[i] )
      {
        led_status[i] = 0;
        led_set[i] = 1; 
      }
      else
      {
        led_status[i] = led_set[i];
      }

    if ( led_status_buf[i] != led_status[i] )
      update_blynk_status[i] = 0; 
  }
28

Try this

for (i = 0; i < 60; i++) {
    led_status_buf[i] = led_status[i];
    bool time_set_overflow = timer_stop_set[i] < timer_start_set[i];
    bool within_time_range = (time_set_overflow && (rtc_sec >= timer_start_set[i] || rtc_sec < timer_stop_set[i])) ||
                             (!time_set_overflow && rtc_sec >= timer_start_set[i] && rtc_sec < timer_stop_set[i]);
    bool within_day_range = weekday_set[i] == 0x00 || (weekday_set[i] & (0x01 << (day_of_week - 1)));
    led_timer_on_set[i] = within_time_range && within_day_range;
    led_status[i] = led_timer_on_set[i] ? 0 : led_set[i];
    if (led_status_buf[i] != led_status[i]) {
        update_blynk_status[i] = 0;
    }
}

Or this

for (i = 0; i < 60; i++) {
    bool within_time_range = (rtc_sec >= timer_start_set[i] && rtc_sec < timer_stop_set[i]) ||
                             (timer_stop_set[i] < timer_start_set[i] && (rtc_sec >= timer_start_set[i] || rtc_sec < timer_stop_set[i]));
    bool within_day_range = weekday_set[i] == 0x00 || (weekday_set[i] & (0x01 << (day_of_week - 1)));
    led_status[i] = !(within_time_range && within_day_range);
    update_blynk_status[i] = led_status_buf[i] != led_status[i];
    led_status_buf[i] = led_status[i];
}

Hi

It seems you did not have this in your code
#include <WidgetRTC.h>
WidgetRTC rtc;

/Torben

this is the Legacy way of using Blynk RTC.

The IoT method is described here:

Hi Pete ´

Thanks for the info, but time sync works perfectly on my device
I will try the new way out

BLYNK_CONNECTED() {
	// Synchronize time on connection
	rtc.begin();
	Serial.println("Blynk Connected");
	Blynk.virtualWrite(V100, 0);
	Blynk.virtualWrite(V101, Version);
	Blynk.virtualWrite(V9, 255);
	Blynk.syncVirtual(V10, V12, V13);
}

It does at the moment, but at some point I suspect that this legacy method will be removed in future versions of the library.

Pete.
