A commissioning session and its related commissioning code allows users of the WiZ Pro Dashboard to give access to the Installers to an already existing Site. This is the code you will need to enter when you select to Join a Site.

To do that, from the WiZ Pro Dashboard, they can generate a code for access. The commissioning code for a specific Site can be generated from the Settings page of this Site.

Note that with this code can come embedded some extra information such as the Wi-Fi network SSID and password, this way you do not even have to fill those in the WiZ Pro Setup app "Connectivity" page, those are pre-filled.
