Return of appliance state after demand response event
First Claim
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.

Abstract
In another aspect of the disclosure, a method of controlling an appliance is provided comprising establishing settings on an appliance related to threshold variables, wherein the settings include the threshold variables for determining a reaction of the appliance in response to reaching one or more of the threshold variables. The method further comprises sending a signal from an associated utility to the appliance, wherein the appliance includes a controller in signal communication with the associated utility. The controller receives and processes a signal from the associated utility, and converts and compares the signal to the threshold variables. The method still further comprises changing the operating of the appliance from a first state of operation to a second state of operation, wherein in the second state of operation one or more power consuming functions of the appliance are based on the comparison of the signal to the threshold variables and, returning the appliance to the first state of operation.
