This deal for a fancier, more expensive equivalent was quite popular at $100 delivered, so I thought I'd pop this one on here.
Keep in mind it does legally require a professional to install it (although as discussed in the linked deal, many people do it themselves).
From the COTD website:
The Efergy meter is a wireless smart electricity meter that allows you to instantly see how much energy you are using at home or in the office. Just clip the sensor around your cables inside your electricity meter box outside, then enter the tariff found on your electricity bill into the display screen inside the house, and the Efergy will display your energy consumption as well as the monetary cost. Using your consumption information from the Efergy meter, you can see how changing your electricity usage will save energy and money. The Efergy stores your usage data too, so you can track how your energy consumption changes over time. The Efergy meter is also an excellent educational device. It is easy to use, and increases awareness of important issues related to electricity, energy and our environment.
