Door status

I want to get door status (Open/Close), how can i get this?

You might need another sensor for that. Maybe something like?: https://arduinogetstarted.com/tutorials/arduino-door-sensor

I think the access controller only unlocks/locks the latch via the relay (and only for a set amount of time). So, you can track whether you told the relay to open/close, but it probably won't know whether the door is actually within the latch.

The RFID board have the door contact.
