Store and app as one: Stadtwerke Duisburg & ROCKETHOME create a modular HEMS for smart energy - local, digital and future-proof.
- Store and app as a strategic unit
- The new Stadtwerke store
- The Stadtwerke Duisburg app
- A strong team and conclusion
Together with us, ROCKETHOME, Stadtwerke Duisburg (SWDU) is setting new standards in home energy, e-commerce and energy services. The aim is to actively shape the transformation from a traditional energy supplier to a digital service provider - modular, efficient and customer-centric.
The focus is on an integrated project consisting of two central components: the new online store "StadtwerkE-Shop" and the new "Stadtwerke Duisburg" app. Both elements are interlinked and only develop their full potential when combined.

Why only together? Store & app as a strategic unit
Stadtwerk Duisburg faced two key challenges:
- Outdated ordering processes: Hardware products such as balcony power plants were sold using simple forms - confusing, time-consuming and hardly scalable.
- Lack of access to dynamic tariffs & home energy services: Although there were already platform solutions for online sales or similar, a consistent solution for modern energy management and smart control was lacking.
The solution: The new store solves the ordering problem. The app makes the products really usable. Only together can a fully-fledged, modular Home Energy Management System (HEMS) be created.
The new Stadtwerke store: Order easily, live energy-consciously
The online store, developed by ROCKETHOME, is directly integrated into the Stadtwerke Duisburg website. It not only makes it easy to order hardware such as smart thermostats or heat pump controls - it is also of central importance for the Stadtwerke Duisburg app.
This is because many of the purchased components can only be intelligently controlled, configured and used to their full extent via the app - making it an essential part of the overall system.
Key features:
- Intuitive product selection and configuration
- Automated fulfillment (warehouse, shipping, support)
- Connection to existing platforms such as "My SWDU"
- After-sales store for products that can be used via the app

The Stadtwerke Duisburg app: managing energy, unlocking potential
The Stadtwerke Duisburg app is also being launched alongside the store. It forms the intelligent control center for all products purchased in the store - from the balcony power plant to the e-car to the heat pump.
Key problems that the app solves:
- Making dynamic tariffs actively usable
- Networking, controlling and automating devices
App functions at a glance:
- Display and use of the dynamic electricity tariff
- Smart charging for e-cars (time- and price-controlled)
- Integration of heat pumps and heating control
- Gateway management for many home energy components
- Scenarios & time controls for more convenience and security
Modularly expandable - step by step to HEMS
The app's functions can be flexibly expanded and adapted to the individual needs of users. If you start with a dynamic tariff today, you can book additional devices and functions at any time via the store. For example, the integration of a gateway enables the use of additional HEMS and smart home functions. The close integration of the store and app makes it easy to discover new solutions and integrate them seamlessly into your own system.

A strong team against big players
With the combination of store and app, Stadtwerke Duisburg is confidently positioning itself in competition with large, technology-driven providers. They are creating a growing, local ecosystem that offers customers real added value - digital, modular and individually expandable. The vision of a fully-fledged home energy management system for Duisburg will only become reality through the interaction of both components.
Conclusion: A project that is growing together - and continues to grow
The partnership between Stadtwerke Duisburg and ROCKETHOME shows how digital infrastructure can be conceived and implemented locally. The key lies in the connection: The store brings the products to the people. The app brings the products to life.
Together, they are turning a traditional municipal utility into a sustainable energy company. Interesting for you too? Please feel free to contact us! To the contact form
