If you want to check if your Easy Kit Connected is already associated with a Legrand account, you must verify it directly on the video internal unit.
Press the configuration joystick on your Easy Kit Connected: if at the top left of the screen there is the WiFi icon and the name of your home WiFi network means that your Easy Kit Connected has already been linked to a Legrand account.
If you haven't made the association and you want to have access to the system you must be invited by those who made the association.
