Retrofitting
phi by Kraus & Naimer offers a modular solution for intelligent acquisition and communication of energy data – flexibly applicable across various industries and sectors. At its core are two key components.
DAT Module
The measurement module (DAT.SA or DAT.KA) precisely measures electrical parameters such as current, voltage and power. It is scalable for various applications and can be installed directly on relevant equipment and machinery.
COM Module
The communication module COM serves as a gateway for up to 16 DAT modules. The data from the DAT modules is transmitted wirelessly to the COM module. Serving as the customer interface, the COM module forwards this data to higher-level systems via standardized protocols such as Modbus RTU/TCP, Ethernet or MQTT. An integrated web server (WebUI) enables user-friendly data visualization and configuration.

Smart energy monitoring for existing systems and buildings
Your challenge
Many existing buildings and production facilities lack adequate systems for energy or condition monitoring. At the same time, demands for transparency, sustainability, and digital traceability are increasing—driven by internal goals, legal requirements, or new regulatory instruments such as the Digital Product Passport (DPP).
For small and medium-sized enterprises (SMEs), a complete overhaul or replacement of existing infrastructure is often economically unfeasible or technically impossible.
Key regulations and standards
The Digital Product Passport will play a central role in the EU’s sustainability strategy. It aims to make information on energy consumption, CO₂ footprint, maintenance history, and material compositiondigitally available throughout a product’s lifecycle. SMEs often face challenges due to lower levels of digitalization, making the implementation of such systems more difficult.
In building technology, the EU Energy Performance of Buildings Directive (EPBD) is particularly relevant. Additionally, ISO 50001, the internationally recognized standard for energy management systems, provides a structured framework for companies to systematically record, analyze, and continuously improve their energy consumption. The Energy Efficiency Act (EEffG) and ESG reporting requirements are also gaining importance.
Our solution
phi by Kraus & Naimer offers a compact, modular solution for retrofitting existing systems and buildings with minimal effort - enabling digital data availability. The measurement modules can be directly integrated into existing machines and systems, while the communication module transmits the data to higher-level systems via MQTT or Modbus RTU/TCP. Additionally, the COM module offers the ability to display the data from connected DAT modules on a local web server.
The intuitive dashboard enables individual configuration. Installation is non-invasive, requiring no changes to existing control systems or processes, and causes minimal operational disruption - ideal for retrofit projects in industry and building technology. phi by Kraus & Naimer thus offers a cost- and energy-efficient solution that also benefits smaller businesses.
The result
By integrating phi modules into retrofit projects, companies can accurately monitor energy consumption, identify inefficiencies, implement targeted measures to improve energy efficiency - all without costly conversions or production downtime. At the same time, this lays the foundation for future-proof digital documentation systems such as the Digital Product Passport.
