An electro-optical, automatic meter reader for enabling a consumer to view and manage power consumption through a browser. A sensor attached to a bracket is mounted to the outside cover of a utility meter without modification of the meter or removal of its housing. A data-collector stores data obtained from the sensor via a serial port which may also provide power for the sensor, thus avoiding use of a dedicated power supply. The data-collector connects to a computer which provides a centralized object through which to view and manage power consumption. The real-time and combined historic data can be used to forecast whether usage will fall above or below a predetermined usage level at the end of a given period of time. In response to a forecast exceeding the level, the computer displays the appropriate graph in a red colored bar within a quantity vs. time chart. The computer may control power consuming devices. A communication system may be established to the system for remote management by the consumer or by the utility company for its own billing and management purposes.
