As a part of our Gen5 range of products, Nano Switch with energy reading (ZW116) is firmware upgradable. Some gateways will support firmware upgrades over-the-air (OTA) and have Nano Switch (ZW116) firmware upgrades packaged as part of their platform. For those that don't yet support such upgrades, Nano Switch with energy reading (ZW116) firmware can be upgraded using Z-Stick from Aeotec or other such Z-Wave USB Adapters such as SmartStick+ from Homeseer, or UZB1 from and Microsoft Windows.


  • Please make sure that you download the correct frequency for your ZW116 Nano Switch with energy reading, firmware updating the ZW116 with energy reading will brick your device and void warranty.
  • Make sure that you do not use this to update the ZW139 Nano Switch without energy reading to avoid bricking the ZW139. This update will not work for ZW139.
