Matter is a technical standard for smart home and Internet of things (IoT) devices. [2][3][4] It is intended to improve interoperability and compatibility between different manufacturers and security, always allowing local control as an option. [5][6][7]

Discover Matter by CSA, the industry-unifying standard for reliable, secure IoT connectivity. Simplify development and build interoperable smart home devices.

Matter has the goal of being an interoperable standard that fosters technology adoption and innovation, gradually replacing proprietary protocols for smart home ecosystems.

Learn how the Matter smart home standard connects Apple, Google, Amazon and Samsung devices in 2026, plus what Thread compatibility really means.

What is Matter for Smart Home IoT? Matter is a unifying standard for seamless smart home connectivity, like Bluetooth. It’s a universal protocol that allows any Matter-enabled device to talk to any other Matter-enabled device or hub, regardless of manufacturer, use case, or smart home framework.

The Matter standard, now in version 1.5, has matured into a proven solution for Internet of Things (IoT) device manufacturers in the smart-home space. This open standard has demonstrated substantial improvements in compatibility and interoperability between devices from different manufacturers.

Defines the foundational components of Matter, how they interact, and the common procedures that underpin the protocol. Details the data models for each cluster that makes up an endpoint, describing their attributes, commands, and events.

Matter is a unified, open-source application-layer connectivity standard built to enable developers and device manufacturers to connect and build reliable, and secure ecosystems and increase compatibility among connected home devices.

Abstract: The Matter specification defines fundamental requirements to enable an interoperable application layer solution for smart home devices over the Internet Protocol. Keywords: Referenced in Chapter 1.

Matter is a smart home protocol standard, which aims to unify device communication across platforms and allows a Matter-enabled device to connect to pre-validated systems. Learn how Matter makes IoT devices secure from DigiCert.
