Enables real time electricity use and cost monitoring * Learn how and where you are using electricity in the home to make informed decisions to reduce usage and cost * Anytime, anywhere feedback also available with the BLI 31000 WiFi Bridge Upgrade Accessory * Helpful estimating function to predict monthly usage based on recent behavior * Helpful appliance function to measure the cost of specific actions or appliances The BLI-28000 PowerCost Monitor (PCM) builds upon the success of its predecessors (BLI-24100/25100) by adding an "Appliance Tab" and "Predictive Usage" feature. As unobtrusive as a small electric clock, the PCM is a powerful real-time direct feedback display device that measures home electricity usage. It tells at a glance, in real-time, how much electricity your home is using in dollars and cents and in kW. Domestic energy usage studies have demonstrated that real-time feedback yields energy savings anywhere between 10 and 20 percent. The savings at the high end of this range are realized when a tabletop energy display device, such as the PCM, is used. The PCM technology consists of two discrete functional units: A detection unit, known as the sensor unit, attaches to an existing household utility meter with a simple ring clamp. The sensor unit is compatible with standard North American digital and electromechanical meter types. This is the only component of the PCM that will be in direct physical contact with the utility's meter. The clamp mechanism allows it to attach to the outside of the meter glass. You can easily quickly attach and detach the sensor without making any changes to the existing meter. The display unit, located inside the home, receives a wireless signal from the transmitter and displays the consumption information in real time and in dollars and cents. Additional information is displayed such as time and outside temperature. Considerations before you order: The PCM uses a wireless signal (433 MHz) to read the information on your utility meter. This means that your utility meter must be located next to your home or within 30 meters (100 ft) of your home. Use the PCM in a single detached dwelling, a duplex dwelling, or a row or town house. The PCM will not work with net metering applications such as wind and solar power, or on a business meter, that uses demand pricing.
