2. When adding, if the screen is not manually woken up, it will not enter the pairing mode and cannot be found.

Check whether the front and back panel of the lock are level with the ground, if there is a tilt to the sides, may lead to the latch stuck, at this time to re-install and adjust it.

This situation indicates that the left and right doors are incorrectly identified, you could set to the correct direction through the DDlock APP, or reset the lock, re-identify the direction.

. Lock status tells if the lock is currently locked or unlocked. 
. Door status tells if the door is open or closed. But this status is based on the door sensor. The door sensor is currently in development.

All generated passcodes can be created remotely without a gateway; However, editing, deleting, or creating custom passcodes requires a Sifely gateway or being within Bluetooth range of the lock.

You can refresh to try again, restart the app, and reinstall the app if necessary.

To change the initially generated passcode and validity period, you must be within Bluetooth range of the lock or remotely via a connected Veise G2 Gateway (sold separately).
