The Alliance is pleased to announce the latest update to Matter, version 1.3 of the specification and SDK, is now available for device makers and platforms to integrate into their products. This latest release marks an important step forward, enabling devices that can be more helpful to users in the kitchen and laundry room, enhance entertainment and smart home interaction on screens, and make the smart home more efficient and safer with new energy and water management support.
The addition of these new device types and functionalities in Matter 1.3 enables product manufacturers and controllers to begin implementing and certifying these features into new and existing products. As our member companies invest the time needed to integrate, test, and deploy new features, updates, and new devices to the market, we look forward to future announcements of products delivering these new capabilities to users through Matter.
With the support of our Membership and the active participation of a strong community of engineers and product experts from across the globe, the Connectivity Standards Alliance and its Members remain committed to Matter as the industry’s best path to delivering increased simplicity, interoperability, security, and value to consumers. With the release of version 1.3, Matter continues to expand its footprint across the smart home industry and the IoT ecosystem.
New Support for Water and Energy Management Devices
- Energy Management — To help users understand and manage their energy use, save money, and reduce their carbon footprint, Matter 1.3 introduces new energy reporting capabilities. This enables any device type to include the ability to report actual and estimated measurements, including instantaneous power, voltage, current, and others, in real-time, as well as its energy consumption or generation over time.
- Electric Vehicle Charging — Matter 1.3’s energy features also enable new energy-centric devices, the first of which is Electric Vehicle Supply Equipment (EVSE). This enables EV charging equipment manufacturers to present a consumer-friendly way to control how and when they charge their vehicles. It features the ability to manually start or stop charging, adjust the charging rate, or specify how many miles of range to be added by a set departure time, leaving the charging station to automatically optimize the charging to happen at the cheapest and lowest carbon times.
- Water Management — Support for leak and freeze detectors, rain sensors, and controllable water valves provide homeowners with enhanced monitoring, management, and protection over water in and around their homes.
New Major Appliance Types
With Matter 1.3, we are adding support for more appliances, encompassing a range of major household devices essential to everyday living.
Among the newly supported device types:
- Microwave Ovens — Users can control the cooking time, power level, and mode of operation and receive notifications, such as “end of cycle” or “food ready” when the microwave completes operation. For a microwave installed in an “over-the-range” configuration, the specification also supports control of an extractor fan and light typical in such scenarios.
- Ovens — Configurations including built-in, stand-alone, or as part of a range with an associated cooktop are included in the Matter 1.3 update. Each oven compartment can be individually controlled from an operational mode (standard, convection bake, roast, steam, broil/grill, proofing) and temperature-setting perspective with information related to the state of the oven (i.e., preheating or cooling). Notifications such as preheating and target temperature achieved are supported.
- Cooktops — With Matter 1.3, there is support for cooktops, allowing for remote access and control (typically induction-based devices). The cooktop’s individual elements allow for temperature control and measurement (where regulation allows).
- Extractor Hoods (Cooker Hoods, Vent Hoods) — Matter 1.3 supports cooktops and ranges in conjunction with cooktop hoods. It allows for the control of both the light and fan settings in such devices, as well as the status/end-of-life of any filter material used (e.g., HEPA filters).
- Laundry Dryers — With Matter 1.2 including support for laundry washers, Matter 1.3 completes the pairing with the addition of support for laundry dryers. Users can set the dryer mode and target temperature and, depending on local safety regulations, remotely start and stop the dryer. Notifications like “end of cycle” and alarms on error states (as vendor-specified) are supported.
Enhanced Entertainment and Smart Home Management Functionality for Media Devices
- Matter Casting Media Players / TVs — Matter 1.3 offers improvements to TV functionality, including push messages and dialog support for new ambient experiences, casting initialization enhancements, expanded interactivity options for TV apps, text and track support, and improved search functionality. Interaction with other devices in the home is also enhanced, enabling other Matter devices to send notifications to TVs or other devices with screens (for instance, notifying that a robot vacuum is stuck, the laundry is done, etc.)
Additional New Features & Core Improvements
The latest update to Matter provides more than new device types and capabilities; it also includes new features and core improvements to enhance Matter-enabled user experiences.
User Experience Enhancements
- Scenes — Scenes are now supported, providing a standards-based method for product makers and smart home platforms to set, read, and activate scenes on devices. Scenes enable users to create a desired state for devices, rooms, or their whole home, by combining settings in devices that can be triggered with one command. For example, a user can set a scene that defines a color and brightness for each of a number of lights, and they can deploy that state synchronously across multiple lights with one command. Devices are also able to store what scenes they are a part of, reducing the number of individual commands needed to execute a scene transition, and improving responsiveness.
- Command Batching — A Matter controller can now batch multiple commands into a single message when communicating with Matter devices to minimize the delay between the execution of those commands. For example, when used with a Matter bridge, batched commands can affect multiple devices allowing the bridge to provide a more synchronized experience. Common examples include minimizing the “popcorn effect” sometimes seen in smart lighting applications.
Debugging and Developer Experience Improvements
- Improved Network Commissioning — Network Commissioning now allows devices to report which Wi-Fi bands they support. Mandatory support of Wi-Fi directed scan improves setup success and enables more actionable connectivity error reporting during setup. For Thread devices, the Network Commissioning cluster now includes attributes to communicate the devices’ Thread version and supported features.
- Event Timestamp Synchronization — Timestamps of events can be synchronized across devices, even if an individual device doesn’t support time synchronization.
- Extended Beaconing Period — Allows devices to beacon (or “advertize”) for longer periods, providing users with a larger time window to commission their devices for the first time.
- Cluster Revisions — Several clusters have undergone noteworthy revisions, including Basic Information, Channel, Door Lock, General Diagnostics, Media Playback, Network Commissioning, Power Source, and Thermostat clusters.
- Automatic SDK XML cluster description from spec text — New tooling eases alignment between the Matter Specification and SDK functions. The tooling makes it easier to develop new standardized clusters. It also promotes interoperability as we apply the tooling to eliminate inconsistencies between the technical spec and the Matter SDK improving the consistency of implementations.

Matter Momentum
With over a year of real-world deployment in millions of households, the Matter Working Group is steadfast in its promise to collaborate across the specification, including improvements to software development kits, certification processes, and individual device implementations, all aimed at continually enhancing the Matter user experience. Looking ahead to the fall release and beyond, we anticipate support for enhancements benefiting all users and devices, including new categories of devices, and enabling users to start, grow, and maintain their secure smart home with smart home-focused networking infrastructure.
