What is M-Bus or Meter-Bus?

M-Bus stands for Meter-Bus and is a European Standard (EN 13757) for remotely reading utility meters including electricity, water and gas. M-Bus uses a two-wire system with a master-slave communications model. The master unit collects data from the slave units, which are the meters being monitored. M-Bus is a popular choice for remote meter reading due to its reliability and ease of installation.
