A Matter device implements several Clusters (functional building blocks) according to its device type: OnOff Cluster for switching, Level Control for dimming, Color Control for RGB, and so on; each Cluster exposes Attributes for state readout and Commands for actions.
True
The Cluster model is the heart of Matter's data plane. The OnOff Cluster (0x0006) exposes a boolean OnOff attribute and the On, Off and Toggle commands. The Level Control Cluster (0x0008) exposes CurrentLevel from 0 to 254 and commands such as MoveToLevel and Step. The Color Control Cluster (0x0300) handles XY, Hue, Saturation and Color Temperature. Device types are defined by composition: an Extended Color Light must implement OnOff plus Level Control plus Color Control, which gives identical command semantics across every vendor that ships that device type.
When you write client code, target Clusters and Attribute IDs rather than vendor names: any certified Extended Color Light will respond to MoveToLevel on 0x0008 regardless of brand.
