Data Acquisition

Consumption Data Acquisition

for Electricity, Water, Heating, Air Conditioning

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.
