description Matter Application Layer Overview
Matter is the application layer protocol that sits *on top* of various transport layers (like Thread or Bluetooth Mesh). It defines *what* the device does (e.g., 'This is a light switch') rather than *how* it communicates. Its adoption is critical because it unifies the user experience, making it the most important layer for future-proofing any new mesh deployment, regardless of the underlying radio tech.

Do I need a smart home hub to use Matter devices?
Yes, most Matter devices require a controller or hub to act as the central brain for automations and remote access. Common compatible controllers include an Apple HomePod, Amazon Echo, or Google Nest Hub.
Does Matter replace Thread or Wi-Fi in smart home devices?
No, Matter is an application layer protocol that sits on top of networking layers like Thread or Wi-Fi. Thread handles how the devices talk to each other locally, while Matter dictates what those devices actually do.
