## What it is
A C++ daemon that acquires utility meter readings from wired m-bus or wireless wM-Bus (OMS) compatible meters using hardware dongles, rtl-sdr receivers, or serial ports. It decodes raw telegrams into human-readable, CSV, or JSON readings and can publish them via MQTT, REST APIs, databases, or log files.

## Use cases
- read water meter readings wirelessly with rtl-sdr
- decode wmbus telegrams from my utility meters
- publish smart meter readings to mqtt for home assistant
- monitor gas and electricity meters on a raspberry pi
- convert mbus meter data to
- collect meter readings from an im871a dongle
- log water consumption over time

## When to choose
- you have wM-Bus/m-bus compatible utility meters and want automated readings
- you want to integrate meter data into home automation via MQTT
- you need a mature decoder with many meter-specific drivers

## When to avoid
- your meters use a proprietary protocol not based on (w)mbus/OMS
- you need a graphical dashboard rather than a decoding daemon
