IZAR@HOME is a smartphone application for consumers that can be used on iOS™ and Android™ operated smartphones.
The application provides consumers a smarter way to learn more about their energy and water consumption at any time, reduce environmental impacts and save money.
Utilities and energy providers can exploit the full advantages of Diehl Metering’s outstanding smart metering technology by adding this solution to their offering for consumers. For the sake of transparency, utilities can provide their customers with current consumption and billing information as well as additional news like maintenance works.
Consumers are in turn empowered to get in touch with their utility/energy providers more easily and efficiently.
In addition, the IZAR@HOME app can reveal potential leaks in households at an early stage. The built-in notification function of the app informs consumers that something is wrong. This means that problems can be quickly corrected before the costs pile up.
