Device Group

Last Updated on : 2024-09-10 08:51:11

A device group is a collection of devices with the same features, allowing users to manage and control a large number of devices as a whole. For example, turn devices on or off, and create scheduled tasks. Group management makes it easier for you to organize and dispatch devices in a more efficient and cost-effective way.

Example

In commercial lighting scenarios, you need to implement modularized management and control of many lights.

You can number all the lights in a commercial building and group them based on the building structure and light type. For example, all lights of the same type and on the same floor can be divided into a light group, and each light group contains several lights. With just a single tap, users can:

  • Turn on or off all lights in the same group.
  • Adjust the brightness of a light group.
  • Control each light group separately.

The APIs often apply to the following scenarios.

  • Create a group: For example, create a group of colored lights manufactured by the same factory.
  • Add devices: For example, add newly installed colored lights to the same group.
  • Delete devices: For example, delete old colored lights from the group.
  • Send group properties: For example, send to the group an instruction to turn off colored lights. Then, all devices in the group will receive the control instruction and go off accordingly.
