Hello,
can anyone help me to change theThe relay should only put on for 3 seconds.

Thank you, it work´s perfect.
greetings Holger

Hm,
now in fhem the state is not transmitted.
-
@the-holgi
That's obvious... as now the state of the lock switches rather fast, the behaviour should be differen. I'd suggest to send both info (on/off) (on before wait(), off after) to get the events in FHEM also.
-
I´ve change the code, now the state on transmitted to fhem, but state off not.
void setLockState(bool state, bool doSend) { if (state) { Serial.println("open lock"); digitalWrite(lockPin, true); wait(5000); Serial.println("close lock"); if (doSend) send(lockMsg.set(state)); digitalWrite(lockPin, false); } }```

@the-holgi this should work
void setLockState(bool state, bool doSend) { if (state) { Serial.println("open lock"); if (doSend) send(lockMsg.set(true)); digitalWrite(lockPin, true); wait(5000); Serial.println("close lock"); if (doSend) send(lockMsg.set(false)); digitalWrite(lockPin, false); } else { if (doSend) send(lockMsg.set(state)); } }

Thank you it works perfect.

Hello,
now i´m write the sketch to another arduino with rfid and relay.
It doesn´t work .
From fhem i can trigger the relay and in serial monitor the card´s where shown with serial.
In fhem the lockstatus is set to off, when the card is in near of the reader, the lockstatus on doesn´t send to fhem.
But the relay doesn´t trigger by card.
Where is the mistake?
The problem is the lockstate doesnt set to on./** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.
