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. The energy provider may then predict the effect a change to the current energy price will have on energy demand, influence the demand in real time by adjusting the energy price, and verify from the smart thermostat that the demand was effected. The user interface displays a bill for an accumulated use of energy either calculated by the processor o…
