@vortigont , Sorry for the inconvenient for putting the new issue with the old issue, your explaining in previous replay , I didn't fully get it as I am still new in programing, as far as I know that the PZEM uses the library pzem-edl to get the data from PZEM module, with the library there is an example and tried it and I got the values I want , but when I combined it with the Main.cpp in the espem folder, the ESP32 is crashes, please advise.
Thanks in advanced.

P.S: the WebUI does not work on mobile phone, any work around ?

yes, in main.cpp you already have pzem-edls pzem object available
try something like this in main.cpp

void mycheck();
Task t_checker;

void setup(){
  //run check every seconds
  t_checker.set( TASK_SECOND, TASK_FOREVER, mycheck );
  ts.addTask(t_checker);
  t_checker.enableDelayed();
}

void mycheck(){
  const auto m = espem->pz->getMetricsPZ004();
  if (m->voltage/10 > 250){
    Serial.println("High voltage!");
    //digitalwrite(alert_LED, HIGH);
  }
}

it works pretty good on mobile, via embedded browser, I have no issues.
I use Service Browser app to discover EmbUI devices in the local network, so you do not even need to enter it's URL, just open WWW HTTP service

@vortigont thanks for your prompt response, the triggering action works fine, void mycheck() runs every second, right? I just wanted to check the interval

@vortigont I used the Service Browser and it works fine, many thanks.
