The Wattson

Easy on the eye, and on the pocket!

Although saving the planet should be one of your top priorities, saving money probably takes precedence. Unless of course you’re one of those sanctimonious superstars who jets (yes, jets!) around the globe telling us mortals (via power-sapping mega-concerts) that we're destroying the environment.

The Wattson

Oooh... lights!

So wouldn't it be cool if you could do your bit to conserve energy and save some wonga to boot? With Wattson you can do exactly that because this ingenious wireless device displays the amount of electricity being used in your house in real time.

Simply plonk the ultra-stylish Wattson receiver in any room and it displays a running total of the energy you're currently using, in either watts or pounds sterling. Turn off a device - TV, microwave, dishwasher - and watch in shame, awe, wonder and relief as the counter goes down. It's a real eye-opener. We've been sitting in the dark ever since we hooked ours up.

Find your meter

Turn on your Wattson

The Wattson


But thats not because we use juicy lightbulbs, it's because Wattson can also communicate info via funky ambient colours. When the lights are blue, energy consumption is low; when they're red, it's high – perfect for educating kids and decadent divvies

The Wattson

Saving money is a bright idea!

Installing Wattson is a doddle: simply clip its transceiver to the wire between your meter and fuse box and you're away. No electrician required. Once you start switching things off and learning how much appliances cost to run, even on standby, you'll be amazed. You'll also think twice before putting the washing machine on to clean a single pair of pants, even if they're your lucky ones.

The Wattson

Communicates with your computer

The USB-friendly Wattson is so clever it can also communicate with your computer. Plug in and you can go online to see how your individual energy savings are making a real difference as part of a collective effort amongst fellow Wattson owners. Brilliant? This whole Wattson concept is elementary!
