EasyX2 only works with Vector X2 controllers (TCX2, TCI2, TRI2, SxC2, SRD2, ... ) with Wi-Fi or Ethernet connection. The app scans the (W)LAN for connected controllers and list the devices. Each controller provides an integrated web interface which can be accessed directly using EasyX2. The X2 commissioning of the controllers need to be done in advance using the software "EasySet".
The WLAN settings can be entered in order to connect a new X2 Vector Controller into the existing WLAN.
