wM-Bus Gateways for Smart Metering
Consumption Data Acquisition
Empty battery in, full battery out.
The idea behind Swobbee exchange stations: Light e-vehicles such as e-cargo bikes or e-scooters use battery packs from the project partners, which can be exchanged for fully charged batteries at the stations at any time of the day. The aim is to appeal to users who need to transport goods in urban or rural areas. These are companies such as logisticians, delivery services, craftsmen and tradespeople above all.
Swobbee is more than just a battery changing system. Swobbee is a smart energy management system with a high degree of customization.
Ready for something new?
The open system from Swobbee allows functional extensions and the integration of other battery types. The built-in technology from pironex makes it possible.
Control and Operating Unit with Linux
The central control element of the charging cabinet is the piA-SF. This Linux IPC with touch display combines a screen, an access control system, system control and charging management into one single unit. Access control is carried out swiftly and securely thanks to the integrated RFID reader. The graphical user interface of the screen ensures an easy operation and intuitive user guidance. The screen robust and protected against vandalism.
Door Control and Charging Technology
The control of the doors, monitoring of the charging processes and charging of the batteries is realized by pironex access technology. It is important to map an optimal energy management for the battery charging station. Communication between the batteries and the chargers takes place via the CAN bus. The CAN / CANopen protocols have been adapted and expanded according to the battery standards. Requirements for high functional safety for charging were programmed on the embedded side.
Battery Detection and Security
System openness is an essential component of the Swobbee infrastructure for battery replacement. In principle, any type of battery from micromobility can be integrated into the changing stations. With Kumpan, Okai, Torrot and GreenPack, four batteries from leading manufacturers are already integrated. Numerous e-kickscooters, e-scooters, e-cargo bikes and more can already be operated today. pironex analyses and integrates the protocols of the battery manufacturers.
Mechanical Functional Construction
Pironex supports the construction of the housing parts. The provision of functional wiring diagrams and 3D models of the corresponding components enabled the engineering colleagues to design and construct different functional battery cabinets. The prototype construction of the systems takes place in close coordination with the designer of the housing shape and the designers of the technical development.

wM-Bus advantages
A wireless M-Bus gateway transmits up to 500 consumption values from water meters, heat meters and heating cost destributors with an 868 MHz (OMS) wireless interface to downstream systems at low cost. The pironex-IoT portal serves as a data collector and as an evaluation platform for the measured values. All encrypted and decrypted consumption data is made available in the IoT platform. The billing company accesses its data via remote maintenance via download or e-mail.
Data Transmission
The wM-Bus Gateway receives wireless M-Bus protocols, filters them as required, stores them and sends them encrypted to a server. The gateway uses existing networks or a mobile data connection for this purpose. The gateway sends the received and filtered data to the server either immediately, hourly, daily or monthly. External services or billing systems can receive and process the consumption values prepared and decrypted from the pironex-iot.de platform via standard APIs (MQTT, REST, HTTP-Push). Direct integration without this platform is possible.
wM-Bus Communication
The wireless M-Bus (wM-Bus) is the wireless version of the wired M-Bus system (meter-Bus). It is standardized in the European standard EN 13757-4 and is suitable for battery-powered devices. The wireless connections work unidirectional and bidirectional and transmit the data from the sensors to the actuators or the meter readings of smart meters.
Remotely Readable Collective Meters
The gateway works with all 868 MHz wireless / OMS water meters, heat meters, heating cost allocators from various manufacturers according to:
- wMbus S1 & C1 & T1 mode (868MHz)
- EN 13757-4
- OMS v3 and v4
- Sensus RF (Bubble Up)
From October 25th, 2020, only readable meters and heat cost allocators may be installed!
Smart Open Metering System
The Open Metering System (OMS) stands for a cross-manufacturer and cross-sector communication architecture for intelligent meters based on the M-Bus (fieldbus) as part of smart metering. It is the only system definition in the world that integrates all media (electricity, gas, heat and water including submetering) into one system.
Online Portal and Native Apps
The gateway, in combination with proven and cost-effective 868 MHz wireless M-Bus meters, is an ideal opportunity to implement the EED directive cost-effectively. pironex supplies the transmission technology from the gateway to the simple download of the consumption data from the pironex-iot.de platform. An app is available for end customers.
