According to one configuration, a remote controller device wirelessly controls a remote media system. The remote controller device includes multiple selectable control buttons, multiple optical sources, and controller hardware. Each optical source individually back-illuminates a respective selectable control button of the multiple selectable buttons. The controller hardware selectively activates different groupings of the multiple optical sources depending upon a current operational mode of the remote media system. For example, a respective user of the remote controller device selects a particular button of the remote controller device corresponding to the first operational mode. The remote controller device, in turn, transmits a wireless signal to the remote media system to control the remote media system to the first operational mode. Rather than illuminating all buttons, the remote controller device then back-illuminates only a relevant group of multiple selectable control buttons applicable to the first operational mode.

A load control device for controlling the power delivered from an AC power source to an electrical load is able to receive radio-frequency (RF) signals from a Wi-Fi-enabled device, such as a smart phone, via a wireless local area network. The load control device comprises a controllably conductive device adapted to be coupled in series between the source and the load, a controller for rendering the controllably conductive device conductive and non-conductive, and a Wi-Fi module operable to receive the RF signals directly from the wireless network. The controller controls the controllably conductive device to adjust the power delivered to the load in response to the wireless signals received from the wireless network. The load control device may further comprise an optical module operable to receive an optical signal, such that the controller may obtain an IP address from the received optical signal and control the power delivered to the load in response to a wireless signal received from the wireless network that includes the IP address.

A control signal receiver of an equipment control device receives a control signal for equipment transmitted by a remote control terminal from a communication device via the Internet. A remote control authorization receiver receives, from a resident of a home, an authorization with respect to the control signal received by the control signal receiver. When the authorization receiver receives an authorization from the resident of the home, an equipment controller controls the equipment on the basis of the received control signal.

In an embodiment, a method for operating a target media device is described. The method includes receiving a user command by a remote control device for operating a target media device, where a signal to operate the target media device is not stored on the remote control device when the user command is received. Data associated with the user command is transmitted by the remote control device to a second media device and signal information, associated with the signal to operate the target media device, is received by the remote control device from the second media device. The signal to operate the target media device is transmitted by the remote control device to the target media device, where the target media device performs a function based on the signal received from the remote control device.
