Wattson

The uber slick and stylish Wattson that shows you how much electricity your home is using, to make energy saving easier.

It can show you in Watts or £s (eek!). The information comes from a transmitter attached to your electricity meter or fuse box. The Wattson is fully portable so you can put it anywhere you like in your home (up to 100 metres through air or 30 metres through walls).

The idea is, if you can see how much electricity you're using, it'll help you use less. The inventors have found that you can save up to 20% on your electricity bills.

Wattson works with any type of UK domestic electricity meter (240V/415V, single or 3 phase).
