This page describes the Lobaro wireless M-Bus gateway firmware, called app-nrf9160-wmbus
, which is executable on different hardware variants sold as different products.
The Lobaro wireless M-Bus gateway firmware collects consumption values from up to 500 commercially available water meters, heat meters, heat cost allocators or similar with 868 MHz wireless M-Bus radio interface or Sensus RF Bubble Up and forwards them encrypted via NB-IoT, LTE-M1 cellular radio or LoRaWAN networks for further processing on the Internet.
Forwarded meter values are transmitted, optionally additionally encrypted via DTLS, to a shared or private instance of the Lobaro IoT platform and can be viewed there or downloaded as a CSV file. Alternatively, standardised APIs such as MQTT, HTTP Push, SFTP or a REST interface are available to connect downstream systems or platforms easily and securely. When using LoRaWAN, the Lobaro Platform is optional. When using NB-IoT or LTE-M, on the other hand, it is mandatory. This requirement is explained in the Lobaro IoT Platform FAQ.
Thanks to the new NB-IoT mobile radio, optimised for sensor data, remote reading even works in places such as basements where smartphones have poor or no reception.
This firmware, following the naming sheme app-nrf9160-wmbus-TZ2-VERSION-HARDWARE, exists in versions targeted for different Lobaro hardware. On all hardware the workflows and functionality is the same. If a certain firmware feature is not available on a specific hardware variant, this will be indicated separately.
This parameter can be used to set whether cellular IoT (NB-IoT, LTE-M) or LoraWAN is to be used for data transmission. With LoRaWAN, the type of network join can also be defined (ABP vs. OTAA).
