Review on Revolutionize Energy Monitoring with Blue Line Innovations BLI 24000 PowerCost BLI-24000 by Jonathan Diaz

I bought the monitor to find out more about my power consumption. It's easy to install, but two major flaws made me return it. First, the data provided is too imprecise to measure performance. The display only shows 1/10kW (so 100W), but the basic accuracy seems to be even worse (maybe 200-300W). In addition, the measurements are not performed in real time - it may take a minute or more for the display to update after the usage mode has changed. Second, the display must be in close proximity to the meter for operation. Inside the house, I often had no reception unless the device was within a few meters (i.e. outside the house). The monitor also lacks memory, so you can't see how you used it during the day. It would be nice to be able to read this through the USB port.
