This application searches for LNI PHGxxxxL gateways, most of which are headless (have no screen), and displays information about each discovered unit. If the unit has been previously setup you can push a button to access the PHGs UI.
However, the main purpose of the Companion is to configure and setup the gateways. It is an automated process where the only action taken by the user is to provide a wireless network. With that information the Companion initiates the setup sequence and displays the process.
Discovery and setup of the PHGxxxxL units is done using Bluetooth.
