The IoT device is elegantly simple. It is a compact black box, powered via USB, that incorporates a button and a red light. There is one device assigned to each mailbox.

When mail is received at the reception desk, it is placed into the corresponding mailbox, and the operator presses the button. The red light blinks for 15 seconds. If the operator presses the button again within this period, the notification is cancelled. If no action is taken within these 15 seconds, an email notification is dispatched to the customer.
