This USB Stick connects a PC or any other computing platform with USB interface to a wireless Z-Wave network. A controller software compatible to the Sigma Designs Serial API is required to use the functions of the device. This software plus this UZB realize a static controller to manage and use Z-Wave devices of various vendors. This stick works with all certified Z-Wave devices regardless of its vendor or date of origin. The Sigma Designs Serial API specification is available to all owners of a Sigma Designs Z-Wave SDK.

• Backup and recovery function including network topology
• Optimized transmitting queue handling to speed up transmitting process
• Firmware update from the OS level in the field
• Trusted Platform module applying strong encryption
