Light Lightness Control Client

The Light Lightness Control (LC) Client configures and interacts with the Light Lightness Control Server.

The Light LC Client creates a single model instance in the mesh composition data, and it can send messages to both the Light LC Server and the Light LC Setup Server, as long as it has the right application keys.

Extended models

None.

Persistent storage

None.
