Abstract: A system for communication between multiple remote meter interfaces (RMI)s and a central office. The system includes multiple RMIs for reading meters and transmitting wireless data signals including meter readout information; multiple base repeater stations for receiving the wireless data signals where each particular base repeater station recognizes the wireless data signal only from particular RMIs that have been identified to the base repeater station, concentrates the information from the identified RMIS, and passes the concentrated information through a master base station and a wide area network (WAN) to a central office. The base repeater station includes a receiver for receiving the wireless data signal, a transmitter for passing concentrated information to the master station, and a microcontroller including an identification (ID) list including the IDs of the RMIs with which the base repeater station is enabled to communicate.

Abstract: A user-responsive system has a controller and a plurality of remotes. Each remote typically has a corresponding sensor and/or actuator. Applications for this system include, but are not limited to heating, ventilating, and air conditioning systems, lighting systems, security systems, energy management systems, home automation systems, and home entertainment systems.

Abstract: A smart thermostat having a transceiver for two-way communication with an energy provider. The smart thermostat includes a temperature sensor for measuring a temperature, a user interface for displaying and receiving information to and from a user, a port connecting to a cooling or heating device, a processor, and the transceiver. The transceiver receives a current energy price from an energy provider. The user interface receives temperature setpoints and associated acceptable energy costs. The processor issues a control signal to the cooling or heating device to operate when the temperature is different than the temperature setpoint and the acceptable energy cost is not greater than the current price of energy. The transceiver transmits information for the control signal, temperature setpoints and associated costs to the energy provider.
