M-Bus to LoRaWAN Converter
M-Bus is widely used on water, heat and BTU/chilled-water meters. An M-Bus-to-LoRaWAN converter reads one or more meters and sends their values wirelessly, enabling automated meter reading without a wired M-Bus master network.
- What problem do we solve?
- Tenant and district-cooling meters often have M-Bus ports that are never connected, leaving billing dependent on manual reading.
- How do we solve it?
- MatrixAI engineers the M-Bus / wM-Bus ↔ LoRaWAN conversion — device audit, converter selection, mapping, decoding and commissioning.
- What technologies do we use?
- M-Bus, LoRaWAN, network server codecs, MQTT / REST
- What can we integrate?
- IoT platforms, BMS, CAFM, SCADA, billing and cloud services

FAQ
M-Bus integration questions
Can one M-Bus converter read multiple meters?
Many converters support several meters on the same M-Bus segment. The number is limited by the converter's M-Bus load capacity and LoRaWAN payload size.
