I’m as straightforward to use as wattson. Set me up correctly, and I talk to wattson whenever you plug him into a spare USB port on your computer. He tells me about the amount of energy you’ve used since he and I last spoke, and I store all this information on your computer.
I was created to show you visually what those numbers on wattson’s display actually mean. It’s all very well knowing that you if switch off the washing machine, TV and computer, your energy use will drop. What you want to know is how much you’re spending on electricity, when you use it most, and how to reduce what you use when you don’t need it.
I draw graphs to show you how you’re doing on energy use over hours, days, weeks or months. I also let you set a target for electricity use reduction, so you have something positive to work towards. Everything you need to know about getting the most from me is in my User Guide










We’ve got the figures back and they’re astounding.
We now have fully researched and tested data back from an online survey of our customers that shows people using Wattson are saving on average 20% on their household energy bills!
And going into next year, that’s going to be a big deal for a lot of homes. So much so that we’re going to organise a campaign about it. Because with a Wattson installed, we think people can be really ambitious with their energy-saving plans. We think you can aim to save 20% in 2010. So we’re calling the campaign 20TEN and we want you to sign up to it at www.wattson.co.za/20TEN
