Matter 1.6 Update Introduces NFC Commissioning and Multi-Platform Support

The Connectivity Standards Alliance (CSA) has released the Matter 1.6 specification, a technical update designed to streamline smart home device setup and improve interoperability between different control ecosystems. The update introduces bi-directional NFC commissioning to simplify device provisioning and a “Joint Fabric” feature to allow multiple smart home platforms to manage a shared network through a central DataStore.

This latest iteration of the Matter protocol addresses long-standing friction points in the smart home industry, specifically regarding the difficulty of adding new devices to a network and the limitations of managing devices across competing platforms like Apple Home, Google Home, and Samsung SmartThings. By refining how devices communicate during setup and how they handle automated commands, the CSA aims to create a more stable and user-friendly environment for consumers.

How does Matter 1.6 simplify smart home device setup?

One of the primary technical shifts in the Matter 1.6 update is the implementation of full bi-directional Near Field Communication (NFC) commissioning. In previous versions of the protocol, while NFC could be used to initiate a connection, the process still relied heavily on a Bluetooth Low Energy (BLE) handshake to complete the setup. If the BLE connection was unstable or dropped during the exchange, the device provisioning process would fail, often requiring users to restart the setup from the beginning.

According to the Connectivity Standards Alliance, the Matter 1.6 update allows the entire commissioning exchange to occur over NFC. This change reduces the dependency on Bluetooth during the initial handshake. The technology enables users to provision devices, such as smart bulbs or in-wall switches, simply by holding their smartphone near the hardware. This process can function even before a device is fully connected to mains power, provided the NFC component is active.

What is Joint Fabric and how does it improve multi-platform homes?

For users who operate devices across different ecosystems—such as a household where one person uses an iPhone and another uses an Android device—managing a single smart home network has historically been difficult. Matter 1.6 addresses this through the introduction of “Joint Fabric.”

The Joint Fabric feature allows multiple smart home platforms to co-administer a single Matter network by utilizing a central DataStore. Under this model, a device is set up once on the shared network, and its control information is made available to all authorized platforms. This enables users to control the same set of devices through their preferred application—whether that is Apple Home, Google Home, or Samsung SmartThings—without the need to manually switch ecosystems or create redundant connections for every new gadget.

How do smart thermostats and safety sensors benefit from the update?

The Matter 1.6 specification also introduces more nuanced communication protocols for specific device categories, most notably smart thermostats and safety sensors. The update shifts the way thermostats handle automated instructions, moving from a direct command model to a “Thermostat suggestions” model.

In the previous model, a smart home hub would send a direct command to a thermostat to change the temperature. Under the new specification, the hub sends a time-bound suggestion. The thermostat then evaluates this suggestion against its current operational context, which includes:

• Recent manual adjustments made by the user.
• Current utility demand-response schedules.
• Local environmental conditions and user preferences.

If an automated routine conflicts with the thermostat’s current context, the device can reject the suggestion and log the event in a standard log for the user to review.

Safety devices are also receiving functional upgrades. Matter 1.6 allows smoke and carbon monoxide alarms to notify the network if they are not mounted in the required position, such as on a ceiling. Additionally, security sensors can now share historical event logs across all connected applications, providing a more cohesive timeline of activity within the home.

When will Matter 1.6 features be available to consumers?

While the Matter 1.6 Software Development Kit (SDK) is now available to device manufacturers and platform developers, these features will not appear in consumer smart homes immediately. The rollout of Matter 1.6 capabilities depends on individual manufacturers implementing the new specification into their products.

Consumers can expect to see these improvements through two primary channels:

• Firmware updates: Existing Matter-certified devices may receive over-the-air (OTA) updates to support new features like the thermostat suggestion model or improved logging.
• New hardware releases: Future smart home products will be manufactured with Matter 1.6 support built-in from the factory, natively supporting NFC commissioning and Joint Fabric.

The timeline for these updates varies by manufacturer and device type.

The next expected checkpoint for the Matter standard will be the release of subsequent technical documentation and implementation reports from the CSA as manufacturers begin integrating the 1.6 SDK into their ecosystems. We encourage readers to monitor updates from their specific smart home hardware providers for compatibility announcements.
