Download Smart Switch 7 EU .OTZ firmware update

Before you update

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

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

Update with an existing Z-Wave hub

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