# Matter

In the Matter standard, a **Cluster** represents a group of device capabilities and behaviors, such as turning a light on/off, adjusting brightness, reporting temperature, or detecting occupancy.\
Each device exposes one or more clusters, which define what the device can do and how it communicates with a Matter controller or Matter Bridge.

Understanding supported clusters helps you determine which device types can be integrated and what features will be available inside **CUBE OS**.
