Download MultiSensor 7.GBL firmware update

Before you update

Please make sure you download the correct Z-Wave Frequency and begin the update with the MultiSensor 7 as close as 10ft / 3m distance to your hub to avoid any possible firmware update issues to avoid bricking your device.

It is highly recommended to run USB power when firmware updating this sensor. 

Warning: Do not update with the wrong Z-Wave Frequency, it will change the Z-Wave frequency of the MultiSensor 7 which would not allow the sensor to re-connect to the same controller. 

Update with an existing Z-Wave hub

In order to use the GBL update files, your Z-Wave gateway must support OTA firmware update. If supported, follow the steps from your Z-Wave Gateway/hub/software to firmware update your MultiSensor.

Update with ZWaveJS UI / ZWaveJS2MQTT:

  1. It is recommended to keep your MultiSensor 7 on USB power for the firmware update.
  2. Download the correct firmware update file above.
  3. Open ZWaveJS UI
  4. Expand MultiSensor 7
  5. Click on Advanced.
  6. Under Firmware update, click on "Begin"
  7. Under File, choose the .GBL firmware update file.
  8. Under Targer, choose Target 0
  9. Then click on OK
  10. Allow the firmware update to complete.

Update using a Z-Wave USB Adapter

If your software does not support .GBL files yet, you can use PC Controller 5 (connected to any standard Z-Wave USB Adapter) by SiLabs to firmware update with GBL files. This software is a Windows exclusive.

You can find that PC Controller 5 here through Simplicity Studio: SiLabs Simplicity Studio

Following the update below, make sure that you have your MultiSensor 7 at most 10ft from your Z-Wave USB Adapter during the update to avoid any failures.

  1. Plug your MultiSensor 7 on USB power.
  2. Follow the steps outlined here to get access to Simplicity Studio and PC Controller 5:
  3. Download the correct Z-Wave Frequency firmware update for your MultiSensor 7.
  4. Open up Z-Wave PC Controller software through Simplicity Studio
  5. Plugin your Z-Wave USB Adapter
  6. Click on the "Gear" icon and select the COM port your Z-Wave USB Adapter is connected to.
  7. Click on "Network Management"
  8. Click on "Remove", then tap the button on MultiSensor 7.
  9. Click on "Add",  then tap the button on MultiSensor 7.
  10. Deselect all security options (this will help speed up your firmware update process), then press OK.
  11. Click and highlight your new MultiSensor 7 Node.
  12. Click on the Home icon button on the top left corner.
  13. Click on OTA Firmware Update.
  14. Ensure your MultiSensor 7 node is highlighted, then press Get.
  15. Under Firmware Update, click on the folder icon.
  16. Then select the firmware update file you downloaded on step 2 of these instructions, then click Open.
  17. Highlight Target 0 (under Firmware Targets:).
  18. Then click on Update.
  19. Wait a few minutes while you wait for the firmware update to finish.

(Optional/Recommended) After firmware updating.

The new MultiSensor 7 firmware contains some changes in its parameter settings that may require you to factory reset your sensor. By performing a manual factory reset, this will set all parameter settings to their default values.

Parameter settings are persistent in this sensor so an exclusion will not reset them to their default values.

To manually factory reset:

  1. Exclude your MultiSensor 7 from your network (to avoid leaving a phantom node, this is a recommendation but not necessary since manual factory reset will issue a factory reset command to remove it from your network, but in some cases it may not do so).
  2. Press and hold the MultiSensor 7 action button for 22+ seconds to manually factory reset.
  3. Re-pair the sensor back into your Z-Wave network.
