Hey guys, this is my first post here 
First of all I hope, I am right here. I am using an ESP32 working via BLYNK Cloud.
I cant use “delay();” because it pauses the whole script and then i get disconnected from the blynk servers. The programm reads temperature, humidity, co2, etc. and swiches on devices for regualting the humidity, temperature, etc. now i want to attach some ventialors, that should go on for 10 seconds, then off for 30 min and on again for 10 seconds, off for 30min, etc…The code is running fine so far, but i want to swich a device on for a certain time, then off and then wait a certain time before start again.
I tried it already in a few scenarios… but it downs’t work… i pin 27 is attaced to a relays, works fine, but not with a delay or timer command. airflowduration is the time the ventilator should be on and airflowdelay should be for the time when the ventilator is off. Those two variables are set in the blynk web dashboard.
void Airflow()
{
digitalWrite(27, HIGH);
timer.setTimeout(1000*airflowduration, []() {
digitalWrite(27, LOW);
timer.setTimeout(1000*airflowdelay, []() { //
});
});
}
Idk if this is helpful, but I am using Blynk Liberary version: 1.1.0
