Video Of The Week
Clip the wireless sensor to the mains (dont worry its safe), leave the box on the worktop and itll tell you exactly how much energy youre using in either watts or pounds. Turn off the TV or dishwasher – and watch as the counter goes down. Its a really easy way to keep track of what costs you the most money to run – it glows red if youre using lots of power and blue when energy use is low.
