What is M-Bus?

M-Bus (Meter-Bus) is a European standard for remote reading of measuring devices. M-Bus is predominantly used in buildings, for example in electricity meters, gas meters, water meters or other types of consumption meters. It is also used for various sensors and actuators.

The data from the measuring devices are transported via M-Bus to a reading point. This can be either a manual reading station for one specific meter, or a collected reading central for several values from a building.

The main benefit of M-Bus is that it enables remote reading of metering devices which otherwise can be hard to reach. It also makes it possible to gather data from several measuring devices into a central SCADA system for example. This can help building owners streamline their energy consumption substantially.
