The Z-Wave Alliance today announces the release of the 2024B specification package. Packed with enhancements that improve interoperability, security, developer tools, and regulatory compliance, this release sets a new standard for Z-Wave globally. The 2024B Specification Package includes documents that have undergone an Intellectual Property Rights (IPR) review and consists of updates that significantly enhance the Z-Wave Certification Program, introduce new and updated Command Classes, and provide a seamless path forward for developers and manufacturers alike.
2024B is now the in-force specification for Z-Wave worldwide.
Key Highlights of the 2024B Specification
Command Class Updates:
The 2024B release introduces several advancements to Z-Wave command classes that enhance device functionality and interoperability. Notable updates include:
- The User Credential Command Class: Used to manage user Credentials for gaining access to properties, typically through unlocking or opening doors. Those properties could be residential or commercial. Credential types include PIN Codes, Passwords, Radio-Frequency Identification (RFID), Bluetooth Low Energy (BLE), Near Field Communication (NFC), Ultra-Wideband (UWB), and Biometrics. This Command Class employs a user-centric model, allowing multiple Credentials to be associated with one User Unique Identifier.
Updated Certification Requirements:
With the adoption of the latest version of the Compliance Test Tool (CTT) version 3.9.1, the Z-Wave certification process has been refined to ensure devices meet the latest performance, security, and interoperability standards. This includes:
- Support for SmartStart, Security 2 (S2), and Z-Wave Long Range (ZWLR) technologies.
- Streamlined validation to align with global regulatory requirements.
New Certification Tool Features:
The 2024B-2 Certification Program and Tools Update, finalized on January 15, 2025, introduces several developer-focused advancements. Key highlights include:
- Enhanced Range Testing Benchmarks: Improves accuracy in validating device performance across various environments. Provides developers with the opportunity to officially verify if the product has a better range performance than what is required at the minimum.
- Updated Emulator Support: Including support for ZWLR, SmartStart, User Credential Command Class (UCCC), and IP-based devices.
- Controller Design Software Updates: The Certification Portal has been updated to receive Controller Design software submissions from additional silicon vendors.
Regulatory Updates for EU Compliance:
The upcoming 2024B-3 updates will address a critical frequency transition for ZWLR in the European Union, ensuring compliance with new ETSI standards. Frequencies will shift from 864.4 MHz and 866.4 MHz to 864 MHz and 866 MHz, supported by updated PHY specifications and certification packages. This ensures that Z-Wave devices continue to meet regional regulatory standards while maintaining high performance. Members can expect to see the final update made to 2024B by April 2025.
What 2024B Means for You, Z-Wave Technology, and the Boarder Smart Home & IoT Markets
The public release of the 2024B specification not only advances the technical capabilities of Z-Wave devices but also reaffirms the Alliance’s commitment to security, reliability, and innovation. With these updates, developers and integrators can build smarter, more secure products while maintaining seamless compatibility across the growing Z-Wave ecosystem.
This release represents a significant step toward empowering manufacturers, developers, and consumers alike, ensuring Z-Wave remains the gold standard for connected homes and IoT solutions worldwide.
