Hoses that think or even motivate people to conserve water? Kottmann's Smart Home technology measures water consumption, temperature, and pressure, controls water flow, and can be used in various ways in the home. People taking a shower, for example, can see how much hot water they have used on a display on the shower hose. And via smartphone or tablet users can interrupt the supply of water to individual devices that use water, provided that a so-called drinking water actor is installed. If there is a leak, the intelligent hose detaches itself from the water network.
