5 Use case

This guide is based on a home lighting use case involving lights in a home that can be remotely controlled by a user's smartphone leveraging the capabilities of oneM2M. An overview of the use case is shown in figure 5-1. The main components are introduced as follows:

• The lights are deployed in a home and are attached to a home gateway.
• The home gateway communicates with a cloud service platform allowing the lights to be controlled remotely by the smartphone.
• The cloud service platform supports a set of services to enable the smartphone to more easily control the lights in the home. Some examples of services include registration, discovery, data management, group management, subscription/notification etc
• The smartphone hosts an application used to remotely control the lights in the home and supports the following capabilities:
  • Discovery of lights deployed in the home.
  • Sending commands to change light states i.e. ON and OFF.
  • Retrieval of light states.
