When I saw this little device, I thought it was pure genius. The Waterpebble is an elegant solution to learning to conserve water, our most precious natural resource, as well as energy, in the form of wasted hot water. Unobtrusive and quite clever, the Waterpebble sits near the drain, learns from your daily shower habits and indicates, using colored LED, your water consumption in comparison to a baseline you set.
It is also possible to reset the device and create a new baseline to improve on. Hot water use is the second highest energy consumer in an average household and this neat little device can help you reduce your expenses in a reasonable and simple manner.
