Update Nano Dimmer firmware via Z-Stick or Z-Stick Gen5.

As a part of our Gen5 range of products, Nano Dimmer (ZW111) is firmware upgradable. Some gateways will support firmware upgrades over-the-air (OTA) and have Nano Dimmer (ZW111) firmware upgrades packaged as part of their platform. For those that don't yet support such upgrades, Nano Dimmer (ZW111) firmware can be upgraded using Z-Stick from Aeotec or other such Z-Wave USB Adapters such as SmartStick+ from Homeseer, or UZB1 from Z-Wave.me and Microsoft Windows.


Important.

  • Please make sure that you download the correct frequency for your ZW111 Nano Dimmer, firmware updating the ZW111 with the wrong firmware and frequency will brick your device and void warranty.

Download Firmware


Firmware update steps. (Z-Wave firmware update)

  1. Download the correct firmware version under section (Download Firmware), make sure you select the correct firmware for your device to avoid bricking your unit.
  2. Unzip the file "OTA of Nano Dimmer_XX_C_V2_03.zip" (XX in the file name refers to the frequency: US, EU, or AU).
  3. Change the file name "Nano Dimmer_OTA_XX_C_V2_03.ex_" to "Nano Dimmer_OTA_XX_C_V2_03.exe"
  4. Connect your Z-Wave USB Adapter to your Windows PC (can be UZB1, SmartStick+, Zooz Stick, Z-Stick Gen5 or S2), make sure no other software is controlling it.
  5. Open up Nano Dimmer_OTA_XX_C_V2_03.exe firmware update software now.
  6. To connect Z-Stick to software by selecting (Categories -> Settings) on the top left side of the software.
  7. The list should populate with your Z-Stick or other Z-Wave USB Adapter and show any nodes connected to it if any. (controller at the top of the list)
  8. Click on the Nano Dimmer node to highlight it (it should already be paired to your Z-Wave network)
  9. Click on "Node Info" button to get the information from Nano Dimmer
  10. Now on the upper middle side, click on the "Firmware" Tab
  11. Click on "Start" button to start the firmware update.
  12. The green bar should be moving slowly, and you should see a large amount of communication happening. This will take roughly 5 minutes, so take a quick coffee break.
  13. When done, a small popup will appear and say "success", go ahead and click OK.
  14. Now it is important to wait 30 seconds after the firmware update. I would just suggest waiting 1 minute after completing step 26.
  15. You should now remove the Nano Dimmer in any means you'd like such as using the OTA firmware update to do so.
  16. Close the software up.
  17. Add it back into your Z-Wave network of its intended use.
