Hello guys, i have a doubt.
i see this code in mysensors.
RelayWithButtonActuator.ino
- DESCRIPTION
- Example sketch for a “light switch” where you can control light or something
- else from both HA controller and a local physical button
- (connected between digital pin 3 and GND).
- This node also works as a repeader for other nodes

debouncer.attach(BUTTON_PIN);
debouncer.interval(5);

}

*/
void loop()
{
debouncer.update();
// Get the update value
int value = debouncer.read();
if (value != oldValue && value==0) {
send(msg.set(state?false:true), true); // Send new state and request ack back
}
oldValue = value;
}
void receive(const MyMessage &message) {
// We only expect one type of message from controller. But we better check anyway.
if (message.isAck()) {
Serial.println(“This is an ack from gateway”);
}
if (message.type == V_LIGHT) {
// Change relay state
state = message.getBool();
digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
// Store state in eeprom
saveState(CHILD_ID, state);
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
}
}
…
my doubt is:
when i press the button and relay is ON home assistant knows the relays is on and put STATUS ON?
But if I have a button in the home assistant and click OFF … does the relay go off and the status in the home assistant also goes off?
