Descripción
With this Raspberry Pi HAT you can extend your Raspberry Pi with functions for smartmetering. The HAT provides an M-Bus master to which other M-Bus devices such as electricity, water or gas meters (with appropriate interface) can be connected directly.
- galvanically isolated M-Bus master interface
- powered by an external 9..30V DC voltage or by the 5V DC of Raspberry Pi (36V for the MBUS will be generated internally from this voltage)
- maximum 6 load units can be supplied
- used UART selectable via jumper (Raspbery Pi4 or Pi5 only)
- optical display for transmit and receive activity via LED
- connection via pluggable screw terminal
software:
For the Raspberry Pi there is libmbus for a powerful library for C++ that can be used with the M-BUS HAT. If you prefer Python, you should take a look at the pyMeterBus project.
Compatible with: Raspberry Pi B+, 2 B, 3 B, 3 B+, Raspberry Pi 4 B, Raspberry Pi 5, Raspberry Pi A+, 3 A+, Raspberry Pi Zero (W) & Zero2
