I was designed by the nice people at DIY Kyoto to help you do more for the environment. And to do it in style. Of course, they also know you won’t mind saving yourself on average 20% on your annual electricity bills, either. With my friend holmes, I look at the energy your home is using, show you usage in graphs and charts, and help you figure out ways to save electricity.
They are lots of benefits to using Holmes and I to help you save energy and up to 25% on your annual electricity bill. Just take a look at all these features:

- I’m really, really easy to install and set up.
- I show you how much each electrical appliance uses when you switch it on or off.
- My easy-to-read display works in all light conditions and show your home’s electricity usage in watts or cost (£ or €).
- I’m portable and wireless, so you can use me anywhere in your home1.
- My cool, contemporary design looks great whether you live in a palace or a pad.
- I show electricity use in numbers and colours, so you can also use me as a mood light.
- I use just 5 watts on average, which drops to under a watt in low power mode.
- My clever low power mode extends by months the life of my rechargeable display battery.
- I’m completely recyclable – not that you’ll want to be without me.
- I store up to 28 days of electricity use information in my internal memory.
- With my software friend holmes, I give you easy access to daily, weekly and monthly views of your home’s energy use.
- You can use me within an online community2 to swap energy-saving hints and tips.
- I can show you how much energy you’re generating.
- I can measure microgenerated electricity supplies such as solar cells or wind turbines.
- It’s simple to fit an extra sensor so I can measure your home’s electricity generation.
- I can be used in big houses and small businesses that have a three-phase (415V) electricity supply.
