2. Important Considerations Before Use
- Advanced Users Only: This Z-Wave stick is intended for advanced users with programming skills and expert knowledge of computer systems and Z-Wave technology. It is not recommended for beginners.
- NVM Backup Warning: Do NOT apply NVM backups from 500 or 700 series Z-Wave sticks to this device, as it will render the device inoperable (brick).
- Firmware Update Caution: Do NOT apply firmware updates published outside of the official Zooz support portal. Unauthorized updates can brick the stick and void its warranty.
- Required Components: A dedicated computer (PC, laptop, or Raspberry Pi, sold separately) and compatible home automation software (not included) are necessary for system completion.
3. Setup Instructions
3.1 Physical Connection
- Ensure your dedicated computer (PC, laptop, or Raspberry Pi) is powered off or safely prepared for USB device connection.
- Insert the Zooz ZST39 LR USB Stick into an available USB port on your computer. It is recommended to use a USB extension cable to minimize potential interference, especially if the computer generates significant electromagnetic noise.
- Power on your computer.
3.2 Software Integration
The ZST39 LR USB Stick requires compatible home automation software to function. Popular choices include Home Assistant (with Z-Wave JS UI) and HomeSeer.
- Install your chosen home automation software on your dedicated computer.
- Follow the software's specific instructions for adding a new Z-Wave controller. The ZST39 LR should be recognized as a Z-Wave 800 Series controller.
- Configure the Z-Wave integration within your software. For Home Assistant, this typically involves setting up the Z-Wave JS integration.
4. Operating the Z-Wave Stick
4.1 Z-Wave Plus and Long Range Functionality
The ZST39 LR supports the latest Z-Wave Plus and Z-Wave Long Range (LR) protocols. Z-Wave LR significantly extends network coverage, potentially up to one mile in open spaces.

Note: To fully utilize Z-Wave Long Range, your home automation software must support its implementation on the interface side, and the end Z-Wave devices you add to the network must also be Z-Wave LR compatible.
4.2 Adding and Managing Devices
Once the ZST39 LR is integrated with your home automation software, you can begin adding Z-Wave devices to your network. Refer to your software's documentation for specific instructions on:
- Including (pairing) new Z-Wave devices.
- Excluding (unpairing) Z-Wave devices.
- Managing device parameters and settings.
- Performing network healing or optimization.
4.3 Over-The-Air (OTA) Firmware Updates
The ZST39 LR supports OTA firmware updates for compatible Z-Wave devices on your network. This allows for convenient updates without physically accessing each device. Always ensure firmware updates are sourced directly from the device manufacturer or the Zooz support portal.
5. Maintenance
- Keep Clean: Periodically clean the exterior of the USB stick with a dry, soft cloth. Avoid using liquids or abrasive cleaners.
- Optimal Placement: Ensure the USB stick is placed in an area free from excessive heat, moisture, or direct sunlight. Avoid placing it near large metal objects or other sources of electromagnetic interference.
- Software Updates: Regularly update your home automation software and Z-Wave integration to benefit from the latest features, bug fixes, and security enhancements.
6. Troubleshooting
- Device Not Recognized:
- Ensure the USB stick is fully inserted into the USB port.
- Try a different USB port or a different computer to rule out port issues.
- Verify that your operating system has installed the necessary drivers.
- Z-Wave Devices Not Pairing:
- Confirm the Z-Wave device is in inclusion mode.
- Ensure the ZST39 LR is in inclusion mode within your home automation software.
- Check the distance between the ZST39 LR and the device. Try pairing closer to the stick first.
- Perform a Z-Wave network heal or repair within your software.
- Intermittent Connectivity:
- Relocate the USB stick using a USB extension cable to a position away from the computer's main chassis or other electronics that might cause interference.
- Ensure there are enough Z-Wave repeater devices in your network to create a robust mesh.
- Device Bricked After Firmware Update/NVM Backup:
As stated in Section 2, applying NVM backups from older series sticks or unauthorized firmware updates can permanently damage the device. Such actions will void the product warranty. Contact Zooz support for guidance if you suspect a bricked device.
