M-Bus, or Meter-Bus, is a European communication protocol used for remote reading of various types of meters.
The M-Bus protocol is particularly common in building automation to automatically collect consumption data from meters for, for example, electricity, water, and heating.
The M-Bus system is built according to a master-slave architecture, where central master units communicate with several subordinate units, slaves, which can be, for example, meters or sensors.
