Registering a Device

Overview

After a device is registered with ROMA Connect, a unique ID and password are allocated to the device in the system. The device uses the ID and password to access ROMA Connect.

A device that is directly connected to ROMA Connect is called common device, and a device that is connected to ROMA Connect through a gateway is called subdevice.

The following figure shows the relationship between devices and products. Both common devices and subdevices belong to common products. Gateways belong to gateway products. A gateway can connect to multiple subdevices.

Prerequisites

• Each device must belong to an integration application. Before registering a device, ensure that an integration application is available. Otherwise, create an integration application first.
• Each device must belong to a product. Before registering a device, ensure that a product is available. Otherwise, create a product first.
