The Hoffmann family has the clever Sparzähler online from Yello. It makes the yellow electricity visible on the PC second by second. Have a look and see how the Hoffmann family can even "paint" the Cologne cathedral.

What can the Yello Sparzähler online do? And what are the customer´s benefits? A family tells how the yellow meter has changed their energy life.

The color and shape of the Yello Sparzähler clearly communicate the message: The monopoly of the black power meters has come to an end. Yello is the first energy provider in Germany to provide clever electricity meters throughout the country. The new yellow Sparzähler transfers consumption data online to the customer’s PC. This is giving customers full control of their consumption and costs for the first time.

Energy has an impact on our lives – like the weather or world events. Sparzähler customers who use Google can now use the Google PowerMeter to constantly keep an eye on their electricity at home – like they keep an eye on the weather and world events.
