The Connectivity Standards Alliance that includes Apple today announced the latest version of Matter, Matter 1.6. The update focuses on improved device setup, better coordinated device management, and response to control inputs.
Matter 1.6 includes NFC-Based Commissioning for setting up light bulbs in ceiling fixtures, in-wall switches, and other products that need to be configured prior to installation. It allows for setup before the device is fully powered, and it serves as an alternative to Bluetooth LE setup. Users will just need to hold a smartphone near a device to commission it.
For multi-ecosystem device sharing, Matter 1.6 supports "Joint Fabric" as a new approach that expands the Enhanced Multi-Admin toolkit. Joint Fabric lets multiple user-authorized controllers co-administer a single shared Matter network. Any device added to the Joint Fabric is accessible to all participating controllers, which makes it simpler for Android and iOS users in a household to access and control Matter-enabled devices. Matter smart home products can be controlled from any interface or ecosystem without requiring a separate setup of every device for each platform.
Thermostat Suggestions improve how thermostats account for user inputs and preferences. Controllers won't send direct commands to change temperature or mode, but will instead submit a time-bound suggestion tied to the thermostat's supported presets so the thermostat can react based on preferences and environmental conditions. The CSA says the new feature will be helpful in the following situations:
- A user enrolled in a utility demand-response program can configure the thermostat to protect those commitments, preventing an automation from a different ecosystem from accidentally overriding a savings event.
- A user who has chosen to optimize for energy savings, or for humidity control, air quality, or another preference, can have the setting recognized and respected across connected services without needing to configure it in each one.
- A thermostat that was just manually adjusted, on the device or through one ecosystem, can recognize a suggestion arriving moments later from another source and will identify it is likely not what the user intended, and defer.
The update standardizes how devices communicate their capabilities and operational limits, and CO and smoke alarms are now able to indicate when they have been removed from their installed position. Security sensors are also able to interoperably indicate a sensor event history, so ecosystems have access to real-time status and past activity.
Matter 1.6 is available for device makers and platforms to integrate into their products. Apple so far has not been quick to implement new Matter specifications. Matter 1.4 was announced back in November 2024, but Apple Home doesn't support all of the Matter 1.4 features.
In tvOS 27, Apple implemented support for Thread 1.4, improving Matter-over-Thread connectivity. Thread credential sharing allows smart home devices to join existing Thread networks for a true mesh network instead of separate, parallel networks across Thread Border Routers from different manufacturers.
