Developed by the Connectivity Standards Alliance and backed by tech giants including Amazon, Apple, Google, and Samsung, Matter has already begun transforming how we think about smart home connectivity. Matter is a technical standard for smart home and IoT (Internet of Things) devices. It aims to improve interoperability and compatibility between different manufacturers and security, while always allowing local control as an option.

Understanding Matter Protocol becomes essential as more devices gain certification and manufacturers commit to this universal standard. Whether you're planning your first smart home setup or looking to expand an existing system, this comprehensive guide explains everything you need to know about Matter Protocol in 2025.

What is Matter Protocol?

Matter is fundamentally different from traditional smart home protocols. Rather than being just another communication standard, Matter represents an interoperability layer that works across existing technologies—one protocol to connect compatible devices and systems. Smart home devices should be secure, reliable, and seamless to use. And with Matter, they are.

The protocol originated in December 2019 as Project Connected Home over IP (CHIP), when Amazon, Apple, Google, Samsung SmartThings, and the Zigbee Alliance announced their collaboration and the formation of a working group. The goal of the project is to simplify development for smart home product brands and manufacturers while increasing the compatibility of the products for consumers.

How Matter Works Technically

Matter operates on Internet Protocol (IP) fundamentals, which sets it apart from proprietary protocols like Zigbee or Z-Wave. The standard operates on Internet Protocol (IP) and functions via one or more controllers that connect and manage devices within your local network, eliminating the need for multiple proprietary hubs.

The protocol employs a specific suite of IP-based networking technologies such as mDNS and IPv6 for device discovery and communication. By building upon Internet Protocol (IP), Matter will enable communication across smart home devices, mobile app, and cloud services, and define a specific set of IP-based networking technologies for device certification.

Matter-certified products are engineered to operate locally and do not depend on an internet connection for their core functions. This local-first approach ensures reliability even when internet connectivity fails, addressing one of the major concerns with cloud-dependent smart home systems.

Supported Technologies and Networks

Matter's flexibility comes from its multi-protocol approach. The first specification release of the Matter protocol will run on Wi-Fi and Thread network layers and will use Bluetooth Low Energy for commissioning.

Wi-Fi Integration

For high-bandwidth devices like smart displays, cameras, and appliances, Matter utilizes existing Wi-Fi infrastructure. This approach requires no additional hardware investment, as most homes already have robust Wi-Fi networks capable of supporting Matter devices.

Wi-Fi-based Matter devices integrate directly into your existing network, communicating through your router and providing immediate connectivity to cloud services when needed. This proves particularly valuable for devices requiring frequent updates or high-data throughput.

Thread Network Support

Thread represents Matter's solution for low-power, battery-operated devices. Thread is a low-power mesh protocol designed for battery-powered devices, which Matter uses as one of its supported transport layers. Unlike Wi-Fi, Thread creates a self-healing mesh network that extends range and improves reliability for sensors, switches, and other low-power devices.

Thread devices require border routers to connect to your home network. Many existing smart speakers and hubs from Apple, Google, and Amazon already include Thread border router functionality, simplifying deployment for users with compatible ecosystems.

Bluetooth Low Energy for Setup

Matter uses Bluetooth Low Energy exclusively for device commissioning and initial setup. This approach streamlines the onboarding process, allowing users to easily add new devices without complex configuration procedures.

Device Compatibility and Current Support

Matter compatibility has expanded rapidly since the initial 1.0 specification release in October 2022. Version 1.0 introduced support for lighting products (such as mains power plugs, electric lights and switches), door locks, thermostats and heating, ventilation, and air conditioning controllers, blinds and shades, home security sensors (such as door, window and motion sensors), and televisions and streaming video players.
