Summary

The M-Bus (Meter Bus) is a cost-effective fieldbus communication protocol for transmitting energy consumption data. A central master – in this case {{{name}}} – communicates via a two-wire bus (up to max. 250 slaves per segment) with bus devices (e.g., heat meter, water meter, electric meter, gas meter).

This manual page provides an overview of the M-Bus functionality in {{{name}}} devices.
