What the display is showing

The orange wireless LAN lamp (or LED2 if you are looking at the WLAN adapter) stays lit once the unit has joined the home router. Confirm this before registering the unit in the mobile app. If the lamp is lit but the app cannot reach the unit, check that the router itself has internet.
