The CSA has publicly released the Matter 1.5 specification, marking a significant expansion of device types and functionality in the smart-home interoperability standard. With this update, Matter now includes explicit support for camera devices, enhanced control over closures (such as garage doors, shades, gates, and awnings), and advanced energy-management features aligned with evolving grid and device ecosystems.
Matter 1.5 adds a new device category for cameras, enabling streaming video and audio, two-way communication, and richer metadata exchange under the standard. The update extends the “closures” category to allow device makers to model motion types (sliding, rotating, lifting) and mechanisms (single/dual panels, nested operations), thereby supporting more complex devices such as awnings, gates, and automated window treatments. On the energy-management front, the specification introduces mechanisms for exchanging standardized data, such as tariffs, real-time pricing, carbon intensity, and grid signals, between devices, enabling smarter load shifting, demand response, and interoperability across devices from multiple ecosystems.
The CSA notes that developers and manufacturers can access the new SDKs, test tools, and certification infrastructure now, while deployment in consumer products may roll out over the coming months. The organization emphasises that while the specification is available, full ecosystem adoption will depend on device-makers and platforms updating firmware, hardware, and certification to support the new categories. The release aims to simplify integration for manufacturers, reduce fragmentation, and provide broader compatibility for users across smart-home ecosystems.
