Hello, is there a way to set my esp to reset when it loses connection with cayenne? There are cases in which I do not have a very stable connection to wifi and the relays remain on. Thank you!
you can turn OFF relay here:
CAYENNE_DISCONNECTED() {
digitalWrite(relay_pin, LOW);
}
Thanks for the reply. Unfortunately i can’t implement the code. This is the error message.
