What Matter Means to the Smart Home Ecosystem

The Promise of Interoperability

When Amazon, Apple, and Google effectively launched a cease-fire in the smart home market with Project Connected Home over IP (CHIP), now known as Matter, they gave the industry a glimpse into just how important interoperability will be. Understanding that consumer adoption will be directly tied to manufacturers' ability to provide reliable and secure user experiences, Matter is an application layer that will unify devices operating under various IP protocols, allowing them to communicate across platforms. With a Matter certification from the Connectivity Standards Alliance, a product will be compatible with Amazon's Alexa, Apple's HomeKit, and Google's smart home ecosystems. The first Matter devices are expected to hit the market later this year. In addition to being easier to integrate with the most common smart home products and voice assistants, they will also be fortified against a wide range of emerging cyber threats with an architecture that prioritizes a security-first design philosophy.

Simplifying the development of smart home devices for manufacturers, coupled with making the introduction of new devices easier for consumers, are the primary drivers for the Matter standardization. But simplicity and desirable products will only get the industry so far. The value that a selection of safe, feature-rich products will bring to the market can't be overstated. This new era of collaboration will set the stage for smart home innovation.

Industry Focus Shifts to Matter

When we think of a smart device, generally what comes to mind is something that is connected. But that's just the first step. Connected devices are appealing, but when they can integrate across multiple platforms, that's when they have the potential to truly impress. Interoperability across technologies and smart home platforms will have an exponential impact on user experience. Because Matter is an open standard, it will also enable SDK development to further push the boundaries of what devices can do.

One of the most important questions around Matter is how it will affect market dynamics in an already active area. Smart home adoption is increasing to the point where consumers have developed a basic expectation for the level of convenience and comfort smart home devices offer. Interoperability and better security should only encourage adoption, but getting more smart devices into the hands of more consumers is the ultimate goal. Helping device makers focus on specific points of differentiation and value will pave the way for better products, but it will also set a foundation for customers to introduce new devices into their homes and maximize their investment in smart products they may have already committed to.

Navigating the Risks and Rewards of the Matter Standard

The Matter standard is currently in development, and this process comes with some unknowns that understandably need to be considered. One of these concerns is the potential burden certification presents to device makers. Adding development time to projects to account for Matter certification is a valid concern but needs to be weighed against the benefits of a product line that is fully compatible with the most common brand names.

Another potential area of risk is the possibility of encouraging competition between ecosystems. Forcing customers to pick an ecosystem adds a burden they don't necessarily face today. Currently, when a consumer buys a connected device, one of the first things they do is install an app from the manufacturer. This often means having an app for every brand of product in the home, which can become overwhelming quickly. This also means becoming part of the brand's ecosystem. Matter aims to change this by allowing devices to connect to any Matter-compliant ecosystem, reducing complexity for the user and offering a cohesive experience across devices.

However, there are also benefits that come with increased competition. Device makers will need to consider this new potential point of differentiation. Instead of competing based on the performance of their own applications, they now need to attract customers to their ecosystem. Matter doesn't prevent manufacturers from creating their own apps to provide users with branded experiences, but in a Matter ecosystem, it will no longer be a requirement.

Another unknown that accompanies any standardization project is getting companies to work together and building enough interest to draw participants. This challenge has been largely mitigated with Matter, partly thanks to the clout of its founding members but also because the industry recognizes the importance of interoperability. Companies are enthusiastically pursuing Matter designs, and the risks are waning with each revision. The challenge now turns to making the most of the spirit of cooperation and releasing a robust certification when the time comes.

Expanding IoT Reach with Multi-Admin Capability

Matter will bring connectivity to new applications and services by removing barriers for end users as well as developers. For consumers, a healthy selection of Matter-compliant devices that deliver on its promise of usability and interoperability will drive demand. For developers, Matter represents a path forward for working with existing technologies like Zigbee and Z-Wave through the use of bridging products.

Designed to be highly inclusive, Matter devices will also feature multi-admin capability. Instead of requiring discrete device and ecosystem compatibility or connectivity where developers need to create a product specifically compatible with a manufacturer's ecosystem, multi-admin allows the device manufacturer to build once and deploy everywhere because devices can connect to any Matter-compatible ecosystem.

Matter's Security-Centric Approach

One of the foundational elements of Matter is security, which is essential to the smart home market. All Matter devices are part of a blockchain registry from the moment they are manufactured, meaning security elements are integrated into every stage of the lifecycle. At any point in time, a Matter device can be tested for authenticity. There are also a number of rules and methods that prevent network attacks.

For example, if a homeowner shares their Wi-Fi password with a guest, there's nothing that will show them where devices are, what they look like, or what types of devices are connected. With device attestation, users will not be able to introduce a "rogue" node with Matter certification. This is further secured by new levels of hardware security. Silicon Labs' Secure Vault is part of this new generation of silicon and represents a significant step forward in IoT security. Device manufacturers need to manage programming and certificates, and vendors are working together to make that process easier.

Security remains one of the most significant barriers to entry for consumers considering smart home products. With every high-profile breach, it falls to the industry to rebuild trust. This is only possible through collaboration because the problem is more than one company, one product, or one protocol can overcome. Matter is a critical step in overcoming these concerns and establishing a benchmark of trust that manufacturers can build upon.

Whether you're ready to get started with Matter, or your company is still determining its strategy with this technology, Silicon Labs is well-positioned to help you understand what you need to know about Matter and how to start prototyping today.
