Arduino MQTT lots of bugs

btw, according to my delay issue. i see here that you fixed it for somebody else

15 second delay

give this code a try. not sure whether it is the way you wanted. use NO pin on relay. int x; int y; unsigned long lastMillis = 0; unsigned long lastMillis1 = 0; void loop() { Cayenne.loop(); y = digitalRead(DoorStateSensorPin); if ( y == 0) //door is open { digitalWrite(RELAY_CONTROL_PIN, x);//turn on relay delay(100); //this delay in your code is very small. x = 0; digitalWrite(RELAY_CONTROL_PIN, x);//turn off relay if (millis() - lastMillis > 10000) { lastM…

did it work for him? i think thats the same issue as me.
