When you try to add devices to the gateway the leds will be blinking. You do not have to do anything extra after you finish installation of gateway with thr router. When the installation is completed, the gateway will be automatically in pairing mode and now you can add devices to the gateway by simply clicking on ‘Add Subdevice’ section on App home page of gateway.
