Getting customers excited

The combination of a visionary idea, the right strategy, excellent design and clear code makes for an outstanding product. It provides added value and an exciting user experience to Invisia's customers.

How it works

Programmable logic controllers (PLCs) serve as interfaces to all physical devices such as solar systems, charging stations, boilers, washing machines and others. The PLCs supply data and take over all control tasks, even if the VPN connection (Virtual Private Network) to the data storage is interrupted. Depending on their access rights, users can monitor their system at any time via webapp and issue commands such as changing the charging mode of the charging stations, the boiler, etc.

The journey doesn’t stop here.

Even though the vision was clear from the beginning and many functionalities were recorded early in the backlog, the app is being developed step by step. What was once a small app has grown to become a complex system with countless features – without losing sight of its simplicity and intuitive usability.

Strategy and information architecture

Some technical facts

In the development, great importance is being attached to accessibility, performance and security. The app scores A+ in security tests (highest level). HTML5, semantic markups and SVG graphics also support the pleasant user experience.
