Through years of further development of the M-Bus standard, which was made possible by the feedback of the users, the technology offers today many possibilities. Especially for the implementation of sensor applications in harsh environments such as smart metering, M-Bus offers the perfect conditions.

Wireless M-Bus to LoRaWAN Bridge

Wireless M-Bus to LoRaWAN® Bridge

The Wireless M-Bus to LoRaWAN® Bridge is a compact and cost-effective device that collects wireless M-Bus messages from utility meters and forwards them to a LoRaWAN® network.

The bridge allows a flexible configuration of calendar events for WM-Bus reception intervals and status messages as well as device filtering by Manufacturer ID and Device ID (whitelist). The configuration can be managed Over-The-Air via LoRa® messages or via wired serial interface.

iM871A

The iM871A Wireless M-Bus module offers a cost-effective RF solution for smart metering applications connecting water, heat, electricity and gas meters with data concentrators in the 868 MHz frequency band. The module supports all major unidirectional and bidirectional wireless M-Bus modes (S1, S1-m, S2, T1, T2,R2, C1 and C2) in addition to all tolerance specifications. The iM871A is pre-qualified according to EN 300 220  and is fully compliant to the EN 13757-4 standard.
With its link budget of up to 120 dB when operating in R2 mode, the iM871A is especially addressing wireless communication requirements in challenging environments inside residential and commercial buildings. The module has an exceptionally small footprint (16.8 mm x 18.6 mm), comes equipped with a serial interface as well as analog and digital inputs and outputs to accommodate interfaces with a customer’s system. With its different ultra low power sleep modes (e.g. deep sleep < 50nA), the iM871A is well-suited for applications requiring long battery life.
