Middleware-based real-time fine-grain sensing for smart electricity meters

A method of real-time monitoring of electric loads of a plurality of electrical appliances within a household, each of the plurality of electrical appliances connected as a publisher to one Smart Electricity Meter (SEM) processing board of a plurality of SEM processing boards which are mounted adjacent to electrical outlets in the household, comprising:

• periodically monitoring respective sensor data from one electrical appliance of the plurality of electrical appliances and, when there is a change to sensor data, publishing, by the respective SEM processing board, the sensor data for a topic to an intermediate agent of a Data Distribution Service (DDS) processing circuitry, which is mounted at a centralized location in the household;
• subscribing, by at least one subscriber processing circuitry mounted in the household, to the topic for the sensor data of specific electrical appliances of the household;
• control transmission, by the intermediate agent, of the sensor data for the topic to the at least one subscriber processing circuitry that subscribes to the topic;
• performing, by the subscriber processing circuitry, data storage of the sensor data in a storage device and analysis on the sensor data to monitor electric load of the one electrical appliance;
• and
• actuating an actuator upon receiving a respective appliance specific actuator command for the one electrical appliance based on the analysis of the sensor data.
• 12. The method of claim 11, further comprising measuring, by a micro-meter, power consumption of the one electrical appliance;
• and
• programming and configuring the SEM processing board to detect, monitor and control the one electrical appliance.
