For the first time ever, the Connectivity Standards Alliance (CSA) has integrated hybrid deployments and modern cloud-connected product experiences into the smart home ecosystem via secure, external paths.
Through the Transport Layer Security (TLS), Matter 1.5 is introducing cameras, advanced closures, soil sensors, and new energy-management frameworks for the first time since its inception in October 2022. With this update, Manufacturers, platform providers, and integrators, can look forward to bringing new device categories into a maturing architecture that brings video, physical access control, and utility-connected energy services under a unified model.
The 1.5 update comes a year after Matter 1.4 was released on November 2024, bringing in the iconic Home Routers and Access Points (HRAP) network infrastructure that married both Wi-Fi and Thread capabilities. Prior to that, Matter 1.3 roped rudimentary kitchen appliance and utility management into the ecosystem, while Matter 1.2 laid the foundations for an expanded range of smart home appliance connectivity.
Features introduced by Matter 1.5 include:
Native support for cameras that previously required APIs for interoperability
Enhanced closure support for window coverings, gates, and doors
Soil sensors to optimise water management
Advanced energy management that accounts for pricing, tariffs, and grid carbon
Improved data transport with TCP and large messages
Matter 1.5 adds native support for cameras, letting devices that once required custom APIs—like doorbells, security cameras, and baby monitors—connect directly to Matter’s standardized data transport and authentication framework. Cameras can now stream video and audio reliably using WebRTC, supporting secure two-way communication, local network access, and remote access through standard STUN and TURN protocols. The specification also supports multi-stream setups, pan-tilt-zoom controls, configurable detection and privacy zones, and flexible recording options, whether continuous or event-driven, stored locally or in the cloud.
For manufacturers, this creates room to innovate with their own apps and features while staying interoperable across Matter-certified ecosystems. For consumers, it means more choice and flexibility: they can mix camera types, brands, and price points while maintaining seamless integration and control across platforms.

Through a simplified, modular cluster design, Matter 1.5 standardizes how smart homes handle sliding, rotating, and opening movements of closures such as window shades, drapes, awnings, gates, and garage doors. Through this approach, development effort can be reduced by allowing complex products to be built without custom integrations. Similarly, users can enjoy more reliable and predictable control across apps and ecosystems through Matter 1.5 with real-time notifications on device positioning and obstructions.

Soil sensors introduced in this update lets devices oversee moisture and temperature, allowing homeowners or garden systems to track plant and soil conditions more accurately. When paired with Matter-enabled water valves or irrigation controllers, soil sensors can trigger watering on a need-to basis, resulting in more efficient water use, healthier plants, and less water waste – all while eliminating manual monitoring.

Building on earlier releases, Matter 1.5 standardizes how devices share and act on energy information about energy pricing, tariffs, grid carbon intensity, and even power limits. By using this information, devices can calculate actual energy costs in response to the economic climate and regional energy demands, adjusting operations based on user preferences and/or regulatory requirements. Additionally, predictive data from energy-producing devices such as solar systems can be incorporated for further optimization.
Furthermore, new EV charging enhancements means that features such as state-of-charge reporting and bi-directional charging are now certifiable under Matter. This change is especially welcome for those who are interested in EU markets as well as next generation vehicle-to-grid and energy-sharing homes.

With full support for TCP transport, Matter grants devices a more reliable way to send and receive large amounts of data, a crucial function for data-heavy devices such as cameras. This update also provides an added benefit of speeding up firmware updates and transmission of rich data such as images and videos. For developers, TCP support means simplified implementation and reduced errors from packet loss. Meanwhile, end-users can enjoy smoother performance, faster updates, and perhaps most importantly, greater battery efficiency.
