Abstract

A low cost, energy monitoring system comprises a plurality of remote sensors for monitoring energy consumption in specific circuits, or by specific appliances, a adapter that communicates with the remote sensors over a wireless network, and a host device with a display. The remote sensors monitor energy consumption in specific circuits, or by specific appliances, and report the energy consumption by the monitored circuits or appliances to the remote adapter. The adapter stores the energy consumption data in memory and generates output images for display by the host device. The output images are based on display templates stored in the memory of the adapter and define how the energy consumption data is formatted and displayed for the user.

Claims

1. A monitoring system comprising:

one or more wireless sensing devices for collecting energy consumption data,

a host device including a display;

an adapter to removably connect to said host device, said adapter comprising;

a housing;

a wireless transceiver disposed within the housing to receive energy consumption data from the sensing devices;

memory within the housing to store the energy consumption data and one or more display templates, said memory comprising shared memory accessible to said host device;

a processor within the housing and configured to;

communicate information with the host device through the shared memory using a file-based communication scheme, and

create one or more output images based on the energy consumption data and the display templates and to store the output images in the shared memory for retrieval by the host device; and

an interface including a physical connector to removably connect the adapter to the host device and an interface circuit to provide the host device with access to the output images stored in the shared memory.

2. The monitoring system of claim 1 wherein the memory further comprises hidden memory for storing the energy consumption data, said hidden memory being inaccessible to said host device.

3. The monitoring system of claim 1 wherein the processor is configured to generate an output image including the power or energy consumed.

4. The monitoring system of claim 3 wherein the processor is further configured to compute the cost of the power or energy used by one or more of the circuits and to generate an output image including the cost of the power or energy consumed.

5. The home energy monitoring system of claim 3 wherein the processor is configured to group two or more circuits into a circuit group, to compute an aggregate power or energy used by the circuit group, and to create an output image including the aggregate power or energy used by the circuit group.

6. The home energy monitoring system of claim 5 wherein the processor is configured to compute an aggregate cost of the power or energy used by the circuit group, and to create an output image including the aggregate cost of the power or energy used by the circuit group.

7. The home energy monitoring system of claim 2 wherein one of the sensing devices comprises a plurality of sensors for monitoring energy consumption in a plurality of circuits.
