The zencontrol commissioning application allows users to scan control system QR codes to locate control systems on sites users have access to.
To locate a control system first navigate to the site list. From the site list, open the menu by pressing the menu button (three horizontal lines) in the top left corner. Select the "Locate controller" option, this will launch a QR scanner. When you scan the QR code on the zencontrol control system it will send you to the control system list which will be filtered to show the located control system.
If the control system is not claimed an error will show and you will be able to add this control system to a site by following this article. If the control system is not on a site you have access to you will get a message stating "You do not have permission to access to this controller (or the QR code was invalid)".
