Need a holiday gift idea? The Blue Line PowerCost Monitor is predicted to be a huge seller this year, and it’s easy to see why.

This cost and energy meter tells  you, in real time, just how much electricity your household is consuming. Clamp the wireless sensor to your energy meter and it will transmit data to a portable, wireless receiver that displays your energy usage info on a large LCD screen. Program it for your electricity rates and see exactly what your electricity costs are.

What’s really great about this monitor is that it offers exact numbers in real time and it’s portable. Translation: you can literally walk around your house and turn things on and off and see how those items increase or decrease your electric bill.

The Blue Line PowerCost Monitor costs just under $100 (for a limited time) and can be purchased online from Smarthome.
