UZB - the world-smallest Z-Wave USB Stick

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.

The device implements a virtual serial interface used by the Z-Wave application. Linux and Mac OSX has a built in device driver for the stick and will create a new device named like /dev/cu.usbmodemfa131 (OSX) or /dev/ttyACM0 (Linux). Windows  enumerates a new COM device but may  require a device driver uzb.inf available below.

Compared to the standard firmware design used by almost all Z-Wave USB Sticks and other Z-Wave Host Interface hardware, the UZB firmware offers several extensions and enhancements:

  • 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
  • Extended Wakeup Notification
  • Handling to extend battery life time of battery operated devices in the network

The UZB comes with two versions: UZB1 is the plain stick without any additional software license. It can be used with any third party Z-Wave controller software. UZBWAY is the combination of the UZB stick plus a license key for the Z-Way controller software. Z-Way will always require a Z-Wave.Me hardware to run, either a UZB (with license) or a Razberry board.
