Overview​

The Lobaro Wireless M-Bus Gateway is a simple to use, cost and energy efficient device that receives, caches and forwards metering consumption data from up to 500 Wireless M-Bus enabled devices (more on request possible), like water meters, electricity meters, heat meters onto the Internet.

The gateway collects data from all metering device conforming to the 868 MHz Wireless M-Bus standard (EN 13757-4) or uses Sensus RF Bubble UP low power short range FSK radio modulation to broadcast consumption data. Their wireless range is typically only about 50m with this traditional technology. The Lobaro Wireless M-Bus Gateway extends this range by collecting the short range data and then uploads it using modern cellular IoT networks (Narrowband IoT) onto the Internet.

Metering data is send to the Lobaro Platform, were it gets parsed, displayed and made available for further processing. Because most Wireless M-Bus telegrams are encrypted, the Platform allows adding decryption keys for individual meters, so that the data can be decrypted by the Platform.

Basic work cycle​

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 Lobaro wMBUS Gateways are working with every meter using standard 868 MHz wMbus:

Radio (LoRa, FSK, NB-IoT, LTE Cat-M1)​

Female SMA ConnectorAntennaNano SIM
Female SMA ConnectorAntennaNano SIM (4FF) for mobile connectivity

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.

warning

The SIM Cad must be inserted or removed only when the device is not powered.
