E-world 2011: Deutsche Telekom presents an app for saving on heating costs

• Stromboxx: Active control of wireless heating thermostats
• Visualization of savings potential on web platform
• Available as an app for various smartphones

Deutsche Telekom is presenting its Stromboxx solution at the E-World trade fair in Essen at their stand (7-111) in Hall 7. The application, developed by the Dresden-based T-Systems subsidiary, makes it possible to actively control wireless heating thermostats. Consumers can view the savings possibilities over the Internet and create time and temperature profiles for individual rooms. This enables them to only heat the room when it is really necessary. It is also possible to do this on the move by using a smartphone such as an iPhone, an Android or Windows Phone 7.

The Stromboxx can already today give a precise indication of the savings potential of a company or home. The user controls the wireless heating thermostat either manually or via interval timers. If a sensor indicates that a window is open, the heating is automatically switched off. In addition, the system recommends ways to save energy, reminds the user of his energy savings targets or of the importance of ventilation to avoid any build-up of mildew.

The experts are already working on new functions: The Stromboxx will soon enable savings to be made during energy consumption. It recognized devices which require a particularly high amount of energy. These can be switched on or off by timer settings, via remote controls or on the basis of a rate plan. Threshold monitoring reminds consumers on a daily basis about optimizing their energy consumption.

Deutsche Telekom will be demonstrating its energy solutions at E-world 2011, at stand 7-111 (hall 7).

Deutsche Telekom will offset all CO2 emissions generated by its stand by making additional investments in a climate protection project in Brazil.
