The present invention provides a connected device system, comprising a master network device (2) and a device (5) to be integrated into the connected device system (1). The connected device system is adapted to connect the master network device and the device via a wireless network (4). When being added to the wireless network, the device announces itself in the wireless network and provides an upgrade server in the wireless net-work. The upgrade server makes available for retrieval a digital asset indicative of a characteristic of the device. The master network device detects the device in the wireless network based on the announcement, searches for the upgrade server of the device in the wireless network in response to the detection of the device, and retrieves the digital asset from the upgrade server of the device. This leads to an improved way of integrating the device into the connected device system.
