A good-looking dongle (Wattson) that clips into your electricity meter and a brainy piece of software (Holmes) work together to count a household’s electricity use over the last 28 days, making it obvious where you’ve saved power, where it is wasted and how you could further enhance your energy efficiency, thus cutting your energy bills. The dongle shows how much money you’re spending on electricity, and the brightness of the figure denotes how much power you’re draining. The software produces easy to read charts and graphs.
For £100, the pair can be yours from DIY Kyoto – buy it here.
