Unify SDK for Z-Wave IoT Gateway Development

Unify SDK: A Major Step Forward in Z-Wave IoT Gateway Development

The latest Unify Software Development Kit (SDK) release introduces updates designed to bring significant enhancements to Z-Wave support, security, and protocol functionality. This release marks a shift as Unify now focuses solely on Z-Wave, removing support for Zigbee and Bluetooth protocol controllers. Key updates include expanded Z-Wave command class support, the introduction of Z-Wave S2V2 Alpha, and a refined scope for the Matter Bridge. These changes ensure a more streamlined, secure, and efficient development experience.

Key Updates in This Unify SDK Release

Expanded Z-Wave Command Class Support

Z-Wave command classes define the functionalities and capabilities of Z-Wave devices. To improve interoperability, we have added commonly used Z-Wave command classes for this release. This ensures that the core functionalities remain intact while simplifying development and certification.

A fully updated Z-Wave command class list is available, providing developers with a clear reference for supported features. Customers can add their own implementation of command classes if they are not found in the existing tool through the contributor license agreement (CLA).

Splitting of Repository: Sustainability and Modulatory

The latest release has significantly enhanced the user experience by refactoring and splitting the repository into three distinct repositories. Previously, all components were housed in a monorepository, or monorepo, which led to complicated dependencies and code management challenges. By dividing the repository into three separate repos, the codebase is now more accessible and easier for developers to understand and implement. This strategic move aims to simplify the development process, making it more efficient and developer friendly.

Introduction of Z-Wave S2V2 Alpha

Security is a major focus of this release, and we are excited to introduce Z-Wave S2V2 (Security Version 2) Alpha. This update strengthens encryption and authentication mechanisms for enhanced device protection.

The alpha version of S2V2 has already been supported on Z-Wave end devices.

The Unify SDK now integrates S2V2 support on the gateway side, ensuring end-to-end security between the controller and end devices. This enhancement strengthens encryption and authentication mechanisms, providing a more secure development environment. It's important to note that the S2V2 security implementation is currently in its alpha stage on the Unify side, indicating that while the foundational security features are in place, further refinements and optimizations are expected in future updates.

Matter Bridge: Scope Adjustment

The Matter Bridge is a component that facilitates communication between Matter and non-Matter devices (in this case, Z-Wave devices). In this release, we are redefining the Matter Bridge as an example code. Example code provides developers with a functional starting point to speed their development. They can update and modify the code as needed for their specific implementation. The example code provided is designed to be a starting point for developer and is not maintained by Silicon Labs.

Unify SDK is Now Dedicated to Z-Wave Development

With these updates, Unify SDK marks a significant shift, dedicating itself solely to the Z-Wave protocol. By having a single focus, we are making Unify SDK more robust and streamlined for developers. Customers who are currently using Z/IP Gateway can now transition to the Unify Z-Wave Protocol Controller, ensuring continued support and updates. By enhancing Z-Wave command class support, improving security with S2V2, and refining the role of Matter Bridge, this release ensures:

✔ Better interoperability and feature parity with past gateway designs

✔ Stronger security and encryption for connected devices
