1. An assembly, comprising:
at least one processor configured with instructions to:
enter a low power mode of a controlled appliance comprising the at least one processor in which at least one video display of the controlled appliance is not activated to display images and at least one computer network communication element and/or system on a chip (SOC) processor of the controlled appliance is deenergized;
responsive to an infrared (IR) command and/or sonic command and/or non-Internet Protocol (IP) radiofrequency (RF) command from a networked device, energize the video display and configure the at least one computer network communication element and the SOC processor in an energized mode that consumes more power than the low power mode; and
within a period of time under two seconds after receiving the IR command and/or sonic command and/or non-IP RF command from the networked device, receive from the networked device, using the at least one computer network communication element, an IP-based discovery message polling the controlled appliance to establish IP communication between the controlled appliance and the networked device.
