System for rate-related control of electrical loads
First Claim
1. For use with a master controller, a secondary controller for reporting the operation of a plurality of electrical loads in a customer premises, comprising:
- means for communicating with the master controller;
means for displaying messages to the customer;
means for obtaining from the master controller historical energy consumption data for one or more loads; and
means for generating, in response to a request, on the means for displaying, a report describing said historical energy consumption data, wherein the means for generating creates on the means for displaying an indication of the cost of the energy consumed at the premises, as a function of time.

Abstract
An energy management and building automation system including a local area network or home automation data bus such as the CEBus. Each load to be controlled is connected to the bus via a control module. A control module may contain a relay or switch (hereafter referred to as a "breaker" or "circuit breaker") to disconnect the load from the mains upon command or upon occurrence of a power outage, or in either case. Current monitoring control modules determine whether connected loads are drawing current and power monitor modules monitor the power consumed by selected loads (from which energy consumption may be calculated). Both types of monitors may place on the bus messages to indicate load status or changes in load status. A first microcomputer preferably is placed externally to the customer premises, adjacent (or even within the housing of) the electric utility power meter. A second microcomputer preferably is placed inside the customer premises. The two microcomputers communicate with each other and with the various load control modules via the network/data bus.

3. For use with a master controller, a secondary controller for reporting the operation of a plurality of electrical loads in a customer premises, comprising:
-
means for communicating with the master controller; means for displaying messages to the customer; means for obtaining from the mast controller historical energy consumption data for one or more loads; and means for generating, in response to a request, on the means for displaying, a report describing said historical energy consumption data, including the rate at which energy is being consumed at the premises and the rate at which a selected load device has been consuming energy, and wherein the indication of the rate at which a selected load device has been consuming energy is displayed for a selected interval in relation to an indication of the rate at which energy has been consumed at the premises for the selected interval.

4. For use with a master controller, a secondary controller for reporting the operation of a plurality of electrical loads in a customer premises, comprising:
-
means for communicating with the master controller; means for displaying messages to the customer; means for obtaining from the master controller historical energy consumption data for one or more loads; and means for generating, in response to a request, on the means for displaying, a report describing said historical energy consumption data, including the rate at which energy is being consumed at the premises, and wherein the means for generating further creates on the means for displaying an indication of the cost of the energy consumed by a selected load device, as a function of time. - View Dependent Claims (5, 6)
