My BLYNK Timing is not working

Need Help With My Project
1

Hello there, I have a project I have been working on and I finally have the hardware setup. However, I am having problems with tracking timing. I get up to case 3 fine, and then when I am supposed to wait in that state until ElapsedMashTime >= MASHTIME it just clicks right through that state into the next one. It seems like the way I am timing is not working. Any ideas?

//Auto Brewing State decision upfront
if (tanktemp < MASHTEMP && autostart == true && switchState ==0) {
  switchState=1;
}

else if (tanktemp >= MASHTEMP - 8.0 && tanktemp < MASHTEMP - 2.0 && premash == true && mashPID == false && switchState ==0) { 
  switchState=2;
}

else if (tanktemp >= MASHTEMP - 2.0 && tanktemp <= MASHTEMP + 2.0 && premash == true && switchState ==0) { 
  switchState=3;
}

else if (tanktemp <= MASHTEMP - 8.0 && mashrun == true && mashreheat == false && switchState ==0){ 
  switchState=4;
}

else if (tanktemp >= MASHTEMP && mashreheat == true && switchState ==0){
  switchState=5;
}

else if (ElapsedMashTime >= MASHTIME && mashrun == true && switchState ==0) { 
  switchState=6;
}

else if (tanktemp >= 200 && mashend == true && switchState ==0) { 
  switchState=7;
}

else if (reboil == true && switchState ==0){ 
  switchState=8;
}

else if (boilrun == true && switchState ==0) {
  switchState=9;
}

else if (ElapsedBoilTime >= BOILTIME && boilrun == true && switchState ==0) { 
  switchState=10;
}

else if (tanktemp <= 190 && boilend == true && switchState ==0) {
  switchState=11;
}

else if (rechill == true && switchState ==0){ 
  switchState=12;
}

else if (ElapsedChillTime >= CHILLTIME && chillrun == true && switchState ==0) { 
  switchState=13;
}

else if (reheatpremash == true && switchState ==0) { 
  switchState=14;
}

I think it was an issue of bringing up the calculation higher in the code. However if you have other ideas let e know. Thanks.

my IF statements all look like this:

((tanktemp <= MASHTEMP - 8.0) && (mashrun == true) && (mashreheat == false) && (switchState ==0))

not this:

(tanktemp <= MASHTEMP - 8.0 && mashrun == true && mashreheat == false && switchState ==0)

dunno if that helps you though!

t’s probably not helping, but it’s sure making your code more readable :slight_smile: Which in itself can help very well in debugging.
