The meter reports to EnBW once every 15 minutes via your home's broadband connection and within 30 minutes that information is available online through the Web site.

A second option provides real-time data direct from the meter as long as the PC is on the same network. Through this users can instantly see energy consumption and accomplish things like analyzing the usage and the cost of running individual gadgets.

Energy usage is plotted on a graph through which its possible to isolate spikes, such as when a TV is switched on, and then calculate how much it costs to run for an hour or any desired time period. You can also plug in a usage scenario, such as 2 hours per day everyday and surprise yourself by seeing how much you'll spend annually to watch TV.

During a demo at Cebit, the meter was hooked-up to a single appliance, an espresso maker, and after making a single cup it calculated the annual running cost to be around €1.50 assuming four cups per day.

Among the users of the meter is Kröpelin himself.
