Abstract:
1. A home energy management system configured to manage power consumption of a plurality of appliances, comprising: a plurality of appliances, each appliance configured with settings that include a threshold variable for determining a reaction of the respective appliance in response to reaching the threshold variable; and a plurality of controllers, each controller coupled to an associated appliance of the plurality of appliances, wherein the each controller configured to receive and process a signal that encodes a value from associated a utility to the associated appliance coupled to the controller, wherein each controller compares and compare the signal to the threshold variable of its associated appliance, wherein each appliance has a plurality of operating states including a first state of normal operation and a second state of energy savings operation, wherein, if the value is greater than the threshold variable of any of the plurality appliances, the controller coupled to the associated appliance changes operation of the appliance from its respective first state to its respective second state in response to the signal, where operation of one or more appliance functions is modified according to user settings so that said one or more appliance functions remains operational as prescribed by a user in a modified state when said appliance enters its respective second state, wherein, if the value is less than the threshold variable of any of the plurality appliances, the controller coupled to the associated appliance changes operation of the appliance from its respective second state to its respective first state when the signal from the utility is no longer being communicated to the appliance; and wherein each controller of the plurality of controllers implements a respective time delay preset buy the user before changing the operation of the associated appliance coupled to said controller from its respective second state to its respective first state so that all of the plurality of appliances operating in their respective second state are staggered in their return to operating in their respective first state.
