The Wattcher display, designed by Marcel Wanders, shows in a clear and direct way your total home's energy consumption. Many users put the energy display in the living room or kitchen. Family members pass frequently and wonder about the energy flows in the house.

The Wattcher visualizes your energy. You learn more about the large consumers in the home. It also becomes a habit to look at the energy display before going to bed. Wattcher users in general save around 13 % on their electricity consumption. That is about €120,- on an annual basis for an average family. Every year again.

The Wattcher datalogger is an energy monitor that is linked to the modem. The datalogger sends the incoming data from one or more senders to a central database. Via Wattcher Online and Wattcher Mobile you'll see detailled energy patterns and you can follow your savings on the longer term.



The datalogger can be used in conjunction with a Wattcher display set. Existing display sets already in the market, can be used and synchronized with the datalogger. With an additional channel , you can see both consumption and production. So you can aim for a neutral energy balance!


Wattcher Online is an energy saving program, where you can keep track of your daily energy consumption and see your own detailed graphs. You receive an online roadmap around energy issues at home, with saving tips, experiences from other users and useful exercises. You can also share your own experiences on the Forum and compare your energy with others.



Wattcher Mobile is a mobile website that works on any type of mobile phone (Windows phone , iPhone , Android). Central in Wattcher Mobile is a weekly overview, where your daily consumption is compared with a self- imposed daily target: when your consumption is lower than this target at a certain day, the bar turns green, when you're a day above the target, the bar turns red.

You see what average percentage you save (or consume) throughout the week. You also get saving tips and you see a timeline of previous week overviews. The timeline provides a quick overview of how you score every week.
