Overview
The Lobaro Wireless M-Bus Gateway Din-Rail receives, caches and forwards metering consumption data from up to 500 wireless M-Bus enabled devices (more on request possible), such as water, electricity and heat meters. It is powered externally and mounted on a DIN rail or, in the 230 V variant, in a wall-mount enclosure.
The gateway extends the typical ~50 m range of wireless M-Bus meters by collecting their short range telegrams and uploading them via NB-IoT / LTE-M.
The work cycle, telegram deduplication, daily status message and all upload formats are part of the firmware and are described in app-nrf9160-wmbus.
Quick start guide
- Make sure the SIM card is inserted correctly.
- Connect power to the device
- Go to The Lobaro Platform and log into your account.
- Go to "Devices" and select your "Lobaro NB-IoT wMBus Gateway".
- If you have several Gateways: the "Address" is printed on the device's case as "DevEUI".
- You should see all wMBus Telegrams the Gateway collected so far.
- If the data is encrypted (closed lock symbol 🔒), you can add keys for your devices under "Organisation → wMbus".
- Push the reset button inside the device, if you want to trigger data collection (will take several minutes).
Compatible meters
The gateway works with every meter using standard 868 MHz wireless M-Bus (S1, C1, T1), OMS v3 & v4 and Sensus RF Bubble UP.
The supported metering protocols are listed in detail under app-nrf9160-wmbus / Compatible Metering Protocols. Background information can be found in the Wireless M-Bus knowledge base article.
Setting up the device
Interfaces
Connections as on the label:
- Vin - Supply voltage 12 - 24 Volt DC
- GND - Ground
- Vout - same as Vin
- NC - not connected
- NC - not connected
- GND - Ground
- Connected cables must be between 0.05 mm² (AWG30) and 1.31 mm² (AWG16).
- Inserted cable length must be between 6mm and 7mm.
- Recommended wire termination:
- Weidmüller: H0,14/10 GR SV, Article Nr.: 9005180000, 8mm/6mm, max. AWG26
- All cables must only be connected or disconnected while the device is not powered
- Vout only supports small consumers like sensors with ≤ 1W
Power Supply
- Power supply via external mains adapter with 12 - 24 Volt DC

Radio (LoRa, FSK, NB-IoT, LTE Cat-M1)
The antenna is used for different radio technologies based on LoRa, FSK including LoRaWAN® and wireless MBUS S1, C1/T1 Modes (868 MHz), OMS v3 & v4.
The same antenna is also used for communication via NB-IoT and LTE Cat-M1. A Nano SIM (4FF) is required for mobile connectivity.
The SIM Cad must be inserted or removed only when the device is not powered.
