You can keep most of our products up to date by using the OTA (over-the-air) method. Many Z-Wave hubs don't support this type of upgrades yet so we created custom instructions using free third party software to update your devices.
This article covers OTA updates for end devices only, if you have a Zooz Z-Wave stick, please select your product below for dedicated instructions:
- How to update your Zooz ZST10 700 Z-Wave Stick
- How to update your Zooz ZST39 800 Long Range Z-Wave Stick
- There are currently no updates available for the discontinued Zooz ZST10 (500 Series) Z-Wave Stick
Where do I get the firmware files?
We don't currently publish firmware files for our products online to make sure you receive and apply the correct file to your product and avoid accidental damage to the device. Here is how to get access to Zooz OTA firmware files:
- Register your Zooz products here (use one form only, you can enter multiple order numbers or just the one that you find most handy)
- Wait for a confirmation email from our team that your products are now registered and detailed instructions where you can access the OTA files in our support portal. It will arrive within a few hours, even on weekends and holidays.

- If you're on Hubitat C7, click here to learn more about their built-in OTA Update SmartApp to upgrade your devices straight from the hub.

FIRMWARE UPDATE INSTRUCTIONS FOR ALL OTHER Z-WAVE HUBS (Including SmartThings)
Please read ALL of the below instructions and disclaimers very carefully before flashing your device with new firmware. All updates are at your own risk. Products bricked during an update are not eligible for warranty service, replacement, or return.
Before you proceed, please read this!
- Remember to unzip the file after download before using it to update your device. 500 series device files will use the .otz or .hex format while 700 series device files will use the .gbl format.
- Always double check that you're applying the correct firmware file to the right model and version of your Zooz device. Loading the wrong version to your device may deem it unusable.
- You may need to exclude and re-include the device after the update is complete for best performance. Please consider you may need to then rebuild all of your automations and settings for the device.
Troubleshooting Steps
- If you notice an error about the wrong fragment size, please change the fragment size to 20 before attempting the update again.
- If your device doesn't function correctly after the update is complete, please exclude it from your hub, factory reset the device, and then re-include it.
- Firmware updates should usually take anywhere from 5 to 15 minutes depending on connection quality and how much information needs to actually be updated on a given device.
- If it is taking longer than that, please try to bring the hub / controller closer to the device that is being updated.
IMPORTANT: To use the firmware update method described below, you will need:
- Z-Wave USB stick / dongle from any manufacturer
- Click here to get the S2 Zooz Z-Wave Plus Stick
- If you're using one with an open source set-up like OpenHAB you can use the same Z-Wave stick
- Laptop or PC with at least 1 available USB port using Windows OS to run the necessary software
- Simplicity Studio offers Linux / Mac version installers but we're unable to verify these will work for firmware updates
- Device Specific OTA Firmware File
- 500 series devices will use a file format with an .otz or .hex extension
- 700 series devices will use a file format with a .gbl file extension.
- Please register your devices on our Product Registration Portal, which gives direct access to firmware files.
- If you do not see newer firmware available or do not see any firmware updates at all, it means there haven't been any updates and your device is on the latest available firmware for your device version.
