Review on Revolutionize Energy Monitoring with Blue Line Innovations BLI 24000 PowerCost BLI-24000 by Matt Butler

Installation and configuration took about 30 minutes. Simply connect the sensor to an external electricity meter (works with both analogue and newer digital meters), sync the sensor to the display and enter the electricity price. The display worked on the opposite side of the house from the sensor. It tracks usage with a delay of about 10 seconds. It shows both the current cost of power consumption and the cumulative cost since the last manual reset. As a bonus, it also displays the outside temperature.
