You should create 6-digit personal codes in the myParcelHome app once and synchronize them with the box. Next, you communicate these codes in the courier service’s delivery preferences. When the couriers arrive, they will consult these delivery preferences. They can type the code on the keyboard of the box, after which the door opens and your parcels can be delivered. Have a look at the video to see how it works.
