With this FeatherWing you can expand the well-known Feather microcontroller boards from Adafruit, Sparkfun etc. with functions for smart metering.
Feather boards are available from different manufacturers and for different platforms:
The M-BUS slave FeatherWing can be plugged onto a Feather microcontroller board to read consumption meters with a so-called P1 customer interface (e.g. electricity meters in Austria). You can also use the FeatherWing to create your own meters for the M-BUS (e.g. to provide self-recorded data for an M-BUS master).
On our GITHUB account we have provided example code for reading
consumption meters with P1 customer interface and DLMS/COSAM protocol
The Arduino M-BUS meter example shows how you can program your own simple meters.
