With this Raspberry Pi HAT you can extend your Raspberry Pi with functions for smart metering. The HAT provides an M-Bus master to which other M-Bus devices such as electricity, water or gas meters (with the appropriate interface) can be connected directly. The M-Bus interface is an European standard (EN 13757-2 and EN 13757-3) made for communication on two wires, making it very cost effective.


  • M-Bus (Meter-Bus) Master
  • powered by an external 9..30V DC voltage (36V for the MBUS will be generated internally from this voltage)
  • up to 6 unit loads can be powered
  • isolated interface
  • selectable UART via jumper (with Raspberry Pi 4 only)
  • indicator LEDs for RX and TX 
  • removable block terminal for bus connection
  • stackable headers version available
