One functionality that we pretty much from the beginning wanted to include in the gadget was a lab- or test function. By this functionality you can investigate and learn about the power usage of a certain product in your home. This individual knowledge is important for making rational choices about which changes in behavior are going to give the highest effect in terms of saving energy, but it´s also a function that makes the user interact and play with the gadet. Energy investigation should be fun and easy!

Here are some examples of how the test function can be used:

The consumption is set to zero when the gadget is turned to test position. (See display functions in Form for Direction). When you then turn one or more products ON or OFF the gadget shows the difference in watts.

- How much energy can I save when turning OFF my computer?

- I wonder how much energy my Tv uses? Turn ON the Tv.

- If I turn ON the Tv and also the surround sound, then what is the energy usage?
