Silicon Labs Matter#

The Matter protocol leverages existing IP technologies, including Wi-Fi and Thread, to build a unified wireless connectivity ecosystem for smart homes. Internet Protocol (IP)-based networking provides manufacturers with simplified development while improving device compatibility for consumers.

Silicon Labs supports Matter on both 802.15.4 (Thread) and 802.11 (Wi-Fi) transport protocols. The Thread development use case differs from Wi-Fi because the Thread protocol requires an OpenThread Border Router (OTBR).

The Unify Matter Bridge is an application that makes legacy devices, such as Z-Wave and Zigbee devices, accessible on a Matter fabric. It does so by acting as an IoT Service in a Unify Framework.

Path for Development#

These pages are for developing Matter applications with the Matter Extension. The Matter Extension is the preferred development path and is available through Simplicity Studio and Standalone via SLC-CLI. The Matter Extension was previously released as an extension of the Gecko SDK (GSDK). Moving forward, the Matter Extension will be an extension of Silicon Labs Simplicity SDK (SiSDK).

Simplicity Studio is a GUI-based development experience in which you can create production-ready projects from a well-tested library. The Simplicity Studio development path also natively supports development on the Windows operating system. As a result, Windows users should use Simplicity Studio for their development environment. SLC-CLI offers command-line access to application configuration and generation of the Matter Extension.

The Silicon Labs Matter GitHub repo will no longer be updated to reflect newer Matter versions after Matter 1.3. As a result, this is no longer a recommended path for Matter Development of new products.
