System and method for alerting a user on an external device of notifications or alerts originating from a network-connected device

Users are experiencing an increasing number of alerts and notifications on their mobile devices. When it is inconvenient or not possible to view the network-connected device, an accessory can be used to save time and avoid missing notifications. A system comprising a network-connected device and an accessory are provided to address these problems. The accessory is capable of notifying the user of alerts from the network-connected device, allowing the user to quickly be advised of alerts without needing to first interact with the network-connected device. The system includes a method to selectively filter alerts so as to avoid unnecessarily interrupting the user in cases where the network device is inaccessible. The system is also capable of pushing new interface designs and themes from the network device to the accessory to alter the appearance and configuration of its display.
