Hi,

I finally found a way to do it

With help and reading. Thanks to this Forum.

void PsiWatchDog(){   

   if(prevPress == 0)
   {
   prevPress = PSI;
   }

   DateTime now = rtc.now();  
   OneSecond1 = now.second();
   IntervalRTC1 = OneSecond1 - PreviousSec1;

   if (IntervalRTC1 < 0){
   IntervalRTC1 += 60;
   }
   if (IntervalRTC1 >180){ //Wait 3 minutes befoere check PSI increase
   
   currPress = PSI;
   
   if (currPress - prevPress > 30)
   { 
   prevPress = 0;
   lcd_2.setCursor (9,0);
   lcd_2.print ("       ");
   }
   
   else if (stateRELAY1 == HIGH)
   {
   stateRELAY1 = LOW; 
   stateRELAY2 = LOW;
   stateRELAY3 = LOW;

   lcd_2.setCursor (12,1);
   lcd_2.print ("Leaks");
   prevPress = PSI;
   }

   PreviousSec1 = OneSecond1;
   }
}
