Opening the door without using the cloud - When you are near the door, the “Open Door” button turns blue, and pressing the button in this state communicates with the door via Bluetooth, unlocking it and opening the door. In this case, no cloud connection is required, so you can manually unlock the door even when the cloud is down. When the distance from the door is far, the “Open Door” button remains green as before, and pressing it will unlock the door via the cloud.
