Systems and methods for providing energy management utilize wireless wide-area network broadcast signals and a decentralized receiver architecture to allow customers to make informed choices with regard to energy consumption and load shedding for particular appliances. A receiver assembly embedded within an appliance receives a broadcast signal, e.g., an FM subcarrier signal, including tariff data and other electrical grid data. A processor coupled with the receiver controls the appliance in accordance with the received data and in accordance with user-defined preferences. In some embodiments, a transceiver assembly is embedded in one or more appliances in a household. Each transceiver is configured to receive broadcast signals regarding grid data, and to communicate with other appliances and/or a usage meter over a wireless personal area network. Meter data from one or more households may be aggregated and uplinked back to the energy provider or other entities.

An HVAC system comprises a programmable wireless thermostat and a remote receiver unit. The thermostat includes a user interface having one or more displays, user input devices, such as buttons, sliders, or a touch screen, and a backlight. The thermostat may include a proximity sensor, wherein the user interface is controlled based on a user's presence near the thermostat. A thermostat controller enters into a reduced energy consumption mode and switches the user interface to an idle state when the proximity sensor indicates a lack of user proximity for a predetermined duration. When the proximity sensor indicates user proximity, the controller exits the reduced energy consumption mode and switches the user interface to an active state. During the reduced energy consumption mode, the user interface may be concealed when the user interface is in a housing which is transparent when backlit but is opaque otherwise.

Remote control of energy consumption is realized using a readily installable, flexible approach. According to an example embodiment of the present invention, a remote source communicates with a wireless controller for executing energy usage control. The remote source sends signals to the wireless controller via a gateway located near or, in one implementation, forming part of the wireless controller. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump. With this approach, wired connections from the gateway to energy-consuming equipment do not necessarily need to be made in order to effect remote energy-consumption control. For instance, when used in connection with a controller wired to the energy-consuming equipment, the gateway need only communicate wirelessly with the controller and does not necessarily need to be coupled to the energy-consuming equipment. In addition, access to the energy-consuming equipment for establishing remote energy control is not necessary; rather, the remote energy control can be effected by accessing user-friendly locations, such as those where thermostats and other controllers are typically located.
