RWE SmartHome

Energy solution to go – control your energy balances simply, conveniently and safely.

RWE Smart Home thermostat and Wifi controller.

From energy supplier to service provider.

With the SmartHome product line designed by designaffairs, RWE offers an innovative, simple energy-saving solution for everyone. With our clever interface metaphors and a simplified, but distinctive product design we not only ensured the straightforward integration and operation, but also facilitated a fast overview of the individual objects as well as the overall energy consumption of the home. The group mastered the transition from a pure energy supplier to a service provider with SmartHome and moved into German homes with its products.

User Interface Design for the RWE SmartHome App.
SmartHome: innovative, mobile and easy to use

We developed an innovative design for the new product family by the energy supplier RWE that made child’s play of the installation, configuration and operation of the home monitoring software. The user can set up and configure his own SmartHome quickly and easily using Drag&Drop. This can then be managed across platforms with a PC, tablet or a smartphone. One glance is all it takes to see and manage the home’s current energy consumption – both from within your own four walls and whilst on the road.

Intuitive logic for complex scenarios

For the innovative SmartHome solution RWE found a partner with designaffairs in 2010 that was able to transfer the complicated configuration scenario into intuitive operations logic for different user and age groups. We implemented the operating interface directly on MS Silverlight. A comprehensive style guide, product manuals and the user guide were all also elements of our project services as well as the integrated App-Store.

Product and interface design go hand in hand

The first step for our strategy team was to create a brand profile with SimuPro®. These results were used as a basis to design a design style that served both as a basis for the industrial design of the individual devices as well as the software user interface design. Our industrial designers then took things a step further by bringing existing products into a consistent form with the new devices. They developed a design for the entire product line that emphasized the affiliation with the RWE group. In order to give the complex software an attractive design and to lend it the same face on all media platforms we worked with the energy group to define use cases that incorporated requirement and function sets. To do so our interface experts created wire frames, screen designs as well as numerous icons and conceived a uniform look and feel. The interaction and design concept was developed in close work groups comprising usability engineers, designers and programmers. The result was agile modules that facilitated a smooth handover to the development department using the Sprint methodology and resulted in an efficient solution.
