IoT Cloud Variables not updated from Dashboard

Hi, the code seems fine.
You're defining pin 5 as output, with pinMode(ledLahto,OUTPUT);

Have you connected a LED or something to pin 5?
Can you share a schema or a picture?

Also, can you try to print something to the serial monitor, in onLedKytkinChange.
Something like

if(ledKytkin==true)  {
    Serial.println("LED ON");
    digitalWrite(ledLahto, HIGH);
  }
  else {
    Serial.println("LED OFF");
    digitalWrite(ledLahto,LOW);
  }

Warning: I haven't tested this code... in case a semicolon or a parenthesis is missing :smile:
