for energy suppliers

Offer more to your customers and increase customer retention.

Cross-platform solution - Connected Anywhere, Anytime

Your customers can access their energy data wherever they are – at home, at work, or on the go. The software runs smoothly across all major browsers and devices. On request, we also publish and maintain your own fully branded mobile app for iOS and Android.

Dynamic Tariffs – Transparent, Efficient, Customer-Centric

With our software, your customers can benefit from all dynamic electricity tariffs – including real-time pricing based on EPEX Spot. The system automatically calculates consumption costs and provides smart notifications when electricity prices are especially low or high. This empowers users to optimize their energy usage, reduce costs, and lower their CO₂ footprint – all supported by intelligent price forecasts for better planning and transparency.

Clear Visualization of Energy Usage

Transparent, cross-divisional visualisation. Our modular structure allows you to decide which details are displayed to your customers and which are not.
  • Dynamic electricity tariffs
  • Consumption, costs & advance payments
  • Feed-In
  • Market price
  • CO2 level
  • CSV export
  • Gas, water & heating
  • Custom arrangement of individual components
  • Automated energy reports

Smart-charging

Activate smart controls and notifications directly via the app.
In combination with PV surplus or dynamic tariffs, we optimize the use of wallboxes, heat pumps, etc. Customers can also activate notifications and receive a message when electricity prices are particularly low, for example.

Solution for Analog & Digital Meters

Offer customers with mME or analog meters the platform as a transitional solution.
  • Manual meter reading: Customers can enter their meter readings manually.
  • All-in-one solution: Customers who do not (yet) have a smart meter can still use the platform.
  • Meter reading submission: Customers can send their meter readings directly to you. By enabling self-reading, bills can be generated and costs can be reduced.

Support of more devices

Do your customers have PV systems, wallboxes, digital electricity meters? We visualize (almost) everything! Users have the option of adding further smart devices. Do you offer battery storage systems, for example? Great, sell them directly via the platform and then have them visualized.

Market digital services and scale to new target groups ‍Realize upselling potential

Increase customer retention through customized subscription models, personalized tips, and your own products or services. Whether it's balcony solar systems or wallboxes – devices can be sold directly via our integrated shop and linked to our simulators. Our sub-client structure also enables seamless distribution of the software to your own customers or business units – including custom app, URL, and full brand integration. The result: new revenue streams, scalable structures, and recurring income from digital services.

reporting functionality

In order to exploit the full potential of the data, we have developed a comprehensive reporting function. This allows you to individually define which data is prepared as visualized reports and at what interval.

  • Set reference values, e.g. consumption per employee or per m²
  • Automate and export your reports
  • Analyze the consumption of your various sources / consumers / devices

Seamless Integration with Minimal Effort

Zählerfreunde acts as an Energy Service Provider (ESA) and supports various methods of receiving metering data – including MSCONS, in addition to its own API. The white-label software can be seamlessly integrated with all common ERP systems, such as SAP IS-U, Wilken, Schleupen, or kVASy (SIV.AG). This enables technical integration with minimal effort and high speed.

Efficient Management with Access Control and Custom API
Keep track of users, buildings, and devices with admin access and an intuitive portfolio overview (including CSV export and project import). Use the custom API to automate the management of spaces, devices, and users—ideal for scalable and efficient operations.

Benefits:

  • Automation instead of manual processes
  • Easy integration with existing systems
  • Standardized and secure data forwarding (MQTT, email, HTTP)
  • Scalable for growing portfolios

Legally compliant solution

As energy suppliers, municipal utilities are obliged from 2025 in accordance with EnWG §40 (§21 - Messstellenbetriebsgesetz (MsbG)) to provide their customers with an itemized and graphical representation of the data on energy consumption and costs. The provision of this visualization serves to ensure consumer protection and transparency. By installing intelligent metering systems (iMSys), customers can better understand their energy consumption and thus make informed decisions.
