Trait Index on iOS

The main purpose of this page is to determine the name of a trait if the only information you have is the ID of the trait. Often, log messages may only include the trait ID. For example, when a trait is unregistered, you'll get a warning that doesn't provide the trait name, which is needed when registering a trait.

Each trait has a unique ID and includes a four-digit string of either 0000 or 6006, which corresponds to the Matter Vendor ID (VID):

• 0000 is the Matter Standard VID, which denotes the trait is derived from a Matter cluster.
• 6006 is the Google VID, which denotes that the trait is derived from a Google smart home trait.

For example, home.matter.0000.clusters.0508 is the Matter trait LowPowerTrait, and home.matter.6006.clusters.fc2f is the Google trait OpenCloseTrait.

For additional information about traits and their usage in the Home APIs, see Traits.
