Overview
Z-Wave 700 Series End Device Software Features and Benefits
The Z-Wave 700 Series End Device software?from Silicon Labs enables end devices such as security sensors, doorlocks, light switches/bulbs and many more to benefit from the pre-certified Z-Wave applications, all certified under the latest certification program from the Z-Wave Alliance.
Z-Wave is designed to meet the demands of the future smart home, where increasing needs for more sensors and battery-operated devices require both long-range and low power. Context-aware environments are the next evolution in the smart home market, and they require technologies that have been optimized specifically for these applications.
Z-Wave creates bold opportunities for new products and applications for next-generation smart home environments. Z-Wave tools enable fast development to enable future context-aware smart home with dozens or even hundreds of smart devices.?

Simplicity SDK Release Notes (2025.6.0)
Latest Release - Q2/2025 ?(June 2025)
Z-Wave and Z-Wave Long Range 800 Version 7.24.0.0
- Key Features
- The Z-Wave stack and associated binary resources are compiled with the Link Time Optimization (LTO) option enabled
- S2v2 draft implementation supports the Supervision Command Class and is aligned with the latest proposed specification
- ZPAL watchdog refactoring
- Z-Wave Power Manager refactoring
- API Changes
- The watchdog is not enabled by stack anymore. It is the application's duty to enable it using zpal_watchdog_init and zpal_enable_watchdog. Application tasks should not block other tasks for more than 4 seconds
- Introduction of zw_power_manager_init(), zw_power_manager_lock(), zw_power_manager_relock(), zw_power_manager_lock_cancel(), to replace and wrap the ZPAL power manager functions. An application must use the zw_power_manager APIs rather than their ZPAL counterparts
- Aligned User Credential Command Class according to the 2025A specification changes by modifying the API of the?CC_UserCredential_move_credential_and_report()?function. The specification for the "User Credential Association Set" and "User Credential Association Report" commands was updated: the option to move a credential to a different slot was removed. Moving a credential to a different slot is still possible via the CLI; however, the lifeline group can no longer be notified about a credential slot change
- App initialization is changed.?main.c?has been removed from the sample applications and is now generated automatically by the?System Setup (sl_main)?platform component instead of the sl_system. For more information, refer to the documentation for?System Initialization and Action Processing
- The Debug Print component was replaced by the ZPAL Log API, which allows filtering log messages by source component and log level
- Bug Fixes
- Below is a list of important bugs fixed in the release. For a complete list, see release notes link
- Fixed an issue where the radio layer would stop receiving packet until the next TX radio event (1409388)
- Fixed a rare occurrence where a null pointer led to a soft reset in the ZAF event queue (1425779)
- Chip Enablement
- None
- None
