FAQ – Frequently Asked Questions about Matter

Smart home standards provide a cross-manufacturer foundation for connecting devices throughout the home. The Matter standard—its first version was approved in October 2022—is already being used in initial product versions. However, it is being introduced gradually, as manufacturers must update older devices or develop new variants to meet the standard’s requirements. To stay up to date with the current development of Matter and to answer frequently asked questions (FAQ), this article compiles information and updates about Matter and helps clarify the most important questions.

Will Matter replace other smart home systems?

Matter is not a smart home system itself; it is a connectivity standard that links devices within the home. A higher-level system is still required to enable automation and control of devices. These roles are currently handled by solutions such as Amazon Alexa, Apple HomeKit, Google Assistant, SmartThings, and others—previously without a shared standard. Matter belongs to the category of communication protocols that define both data transport and data structure. If Matter succeeds, compatibility lists from IoT and smart home manufacturers could eventually become unnecessary.

What are the benefits for users?

With Matter, users can connect and control various household devices more easily. The connectivity standard enables devices from different manufacturers and platforms to be integrated into a unified smart home system. For example, users can control and automate lighting, heating, air conditioning, entertainment electronics, and other devices via app or voice control. Matter expands smart home automation possibilities by creating a unified standard for device communication. This makes setup and control simpler, without worrying about device compatibility. It also allows easier integration of new devices and services, as they are no longer tied to a specific platform or manufacturer. Users gain more flexibility and can expand their smart home system according to their individual needs. Overall, Matter offers a simpler and more flexible way to transform a home into an intelligent and connected smart home.

What does this mean for manufacturers?

For manufacturers of Matter-compatible devices, the standard offers numerous advantages. One of the most important is access to a broader customer base, since products are no longer tied to a specific platform or manufacturer. Another benefit is the ability to integrate products into a larger ecosystem of connected devices and services, enabling additional functionality and new combinations. Matter also allows manufacturers to develop and produce products more easily and cost-effectively, as they are no longer restricted to specific proprietary platforms. Supporting Matter can also provide a competitive advantage over manufacturers that do not adopt the standard. Additionally, manufacturers can participate in the ongoing development of Matter and help shape its future. By integrating products and services into the standard, they can better align them with customer needs. In summary, Matter offers manufacturers benefits such as a larger customer base, broader ecosystem integration, more efficient development and production, competitive advantages, and participation in shaping the standard’s evolution.

What technology does Matter use?

Matter uses several technologies to connect and control devices within the home. The standard is based on a combination of established technologies and new developments. One core technology is Internet Protocol (IP), which enables devices to communicate and exchange data over networks. Matter also uses technologies such as the Constrained Application Protocol (CoAP), designed for devices with limited resources. In addition, secure communication and reliable message transport mechanisms are used to ensure smooth interaction between devices across different networks. Together, these technologies enable Matter-compatible devices to connect and operate efficiently. By building on existing and modern technologies, Matter provides a flexible and future-proof way to network devices in the home.

Who supports Matter?

Matter is supported by a wide range of companies and organizations involved in smart home technology development. This includes major technology and electronics manufacturers as well as startups and non-profit organizations. Well-known brands such as Amazon, Apple, Google, and Samsung support Matter and are integrating it into their ecosystems. Numerous smaller companies are also developing Matter-compatible products. In addition, organizations like the Connectivity Standards Alliance (formerly the Zigbee Alliance) promote and further develop the Matter standard. Overall, Matter is backed by a broad coalition of industry leaders and innovators working to create interoperable smart home solutions.

What does the standard define?

The Matter standard defines a common connectivity framework for household devices to communicate and operate together. It specifies how devices discover each other, exchange information, and maintain secure communication. The standard ensures encrypted communication between devices to protect data and prevent unauthorized access. It also defines common device types and control models, making it easier to integrate devices from different manufacturers. Overall, Matter establishes a unified and secure foundation for smart home interoperability.

Do I need new devices?

Whether you need new devices depends on what you already own and whether those devices are Matter-compatible. If your existing devices support Matter—either natively or through firmware updates—you may not need new hardware. However, older devices that do not support Matter might require replacement or additional bridges or gateways for integration. Since Matter is still relatively new, not all devices currently support it. Over time, the number of compatible products is expected to grow, reducing the need for replacements. Ultimately, the need for new devices depends on your current setup and compatibility.

When will products be available?

New Matter-compatible products are regularly entering the market. As adoption grows, more manufacturers are announcing and releasing devices that support the standard. Product announcements often occur at major technology trade shows such as CES or IFA. However, availability depends on factors such as component supply, production timelines, and certification processes. While the ecosystem is still expanding, the number of Matter-compatible devices is expected to continue increasing in the coming years.

Will Matter become the dominant standard?

Whether Matter will establish itself as the dominant standard for smart home connectivity remains to be seen. It has strong potential due to backing from major technology companies and organizations. This support increases the likelihood that more devices and solutions will adopt the standard. Matter’s foundation on widely used technologies and its focus on interoperability are additional strengths. However, other established standards such as Zigbee and Z-Wave are already widely used. It will take time to see how Matter develops in comparison. While its future dominance is not guaranteed, the factors supporting its success are significant.
