Updating Z-Wave radio on C-7 hubs after version 2.3.8.122

We have identified a limitation affecting only the C-7 models that have been automatically upgraded to the Z/IP Gateway SDK 7.18.03, which was released with platform version 2.3.8.117.

If you have a C-7 hub and already updated to 2.3.8, prior to version 2.3.8.122, and you have a button on the Z-Wave Details page to "Update firmware," you will not be able to update the radio firmware to version 7.18.1.0.

A work around for this limitation is to downgrade the Z/IP Gateway, then update the radio firmware, and then upgrade the Z/IP Gateway again.


For C-7 models that have already been updated to 2.3.8, please follow these steps in order to complete the radio update:

  1. Update hub to version 2.3.8.122.
  2. Go to: yourHubIP*/hub/advanced/installZipgateway715
  3. Reboot the hub from Settings
  4. Go to Z-Wave Details page, then select Update Firmware to install "Z-Wave and Z-Wave Long Range 700/800 SDK 7.18.1.0"
  5. Go to: yourHubIP*/hub/advanced/installZipgateway718
  6. Reboot the hub from Settings

This will complete the upgrade for both Z/IP Gateway as well as radio SDK.


For all other C-7 hubs that have not been updated to 2.3.8, please follow these steps:

  1. Update hub to version 2.3.8.122
  2. Check the Z-Wave Details page to see if a firmware update is available. If it is, then select Update Firmware to install "Z-Wave and Z-Wave Long Range 700/800 SDK 7.18.1.0"
  3. Go to: yourHubIP*/hub/advanced/installZipgateway718 to update Z/IP Gateway to latest version.

NOTE: replace yourHubIP* with actual IP address as assigned to your Hubitat Elevation hub.
