M-Bus HAT for Raspberry Pi v2.0

With this M-Bus HAT for Raspberry Pi, 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.

A datasheet/user guide is available to help you get started. With libmbus, powerful C++ software is available for the Raspberry Pi, which can be used with the M-Bus HAT. If you prefer Python take a look at the pyMeterBus project.
