Not replacing existing technology, but integrating it intelligently
N-ERGIE already had a LoRaWAN® network in place. Naturally, we wanted to continue using this while also investing in scalable future technology. The challenge was to find a solution that would intelligently combine the old and the new without having to completely rebuild everything from scratch
Anja Scheckenbach, Multiconnectivity Order Coordinator & Project Management N-ERGIE
Before the collaboration, a LoRaWAN® network was already in place, used to read various heat and shaft water meters across the city. However, the prerequisites were no longer sufficient for further major development steps – such as the fully automated collection of all household water meters. Therefore, the central task was to establish new technological standards.With one decisive condition: in order to proceed as cost-effectively and sustainably as possible, the existing radio network with the devices already installed should not simply be replaced but intelligently integrated into the new solution.

Hybrid radio network with scalable mioty® technology
The mioty® technology proposed by Diehl was specifically developed for large-scale use, offering significantly improved efficiency compared to the existing LoRaWAN® network and providing virtually unlimited scalability.
In the first project stage in 2023, 30 new radio receiving stations were installed across the city of Nuremberg, along with five more in Fürth, fully replacing the old receiving stations. Additional locations are already planned.
Since the IZAR IoT GATEWAY Premium harmoniously integrates both radio technologies into the system, existing meters can continue transmitting via the old standard, while all new devices use mioty®.
For fully automated household readings, new ultrasonic water meters, our HYDRUS 2.0, were and are being installed citywide starting in 2024 – with around 21,300 units connected to the network by March 2025.

Automated reading. Leakage detection. Future potential.
The hybrid network provides us with up-to-date insights into the status of our supply network. This enables us to respond quickly to faults and take corrective action.
Markus Greiner, Expert in pipe sections N-ERGIE Netz GmbH
The N-ERGIE team already saves considerable time in collecting and verifying meter readings and can rely on accurate, up-to-date data for billing. Customers, in turn, no longer need to schedule on-site appointments or submit meter readings themselves.The new sensors are also capable of issuing alerts in the event of possible leaks, increasing the security of the pipeline network and potentially saving up to 20% of the supplied water that would otherwise be lost through undetected leakages.
Operating the new devices requires significantly less energy, and thanks to the roughly doubled range of the mioty® technology, fewer locations are needed for installations. In addition, the system now opens up expansion opportunities that go far beyond water network monitoring: with the right sensors, for example, district heating pipelines can be monitored, parking space occupancy can be tracked, or water levels in underpasses can be checked during heavy rainfall.
There are already considerations to extend Diehl Metering’s digital monitoring technologies to the district heating sector as well, both to simplify reading processes and, through data analysis, to optimize power plant operations.
