The Wattson is a device that shows you how much electricity you're using and so will help you to work out your carbon footprint, and where you can save electricity and money.

Customer Reviews

My wife wanted to get an Efergy but after speaking with Dorian at It Must Be Green I just had to get the Wattson - and I'm so glad I did. It's a really smart bit of kit, it both looks great and syncs up with my PC, allowing us to track our spending and have some nerdy fun while we're at it - all in all, brilliant!
