Hardware

This software will read out a M-BUS slave device connected to an M-BUS master shield. We offer 3 different boards:

Arduino MKR M-BUS Master shield:

Raspberry Pi Pico MBUS Master HAT:

MBUS Master Featherwing:

Data decoding

The decoded data is output in JSON format via the UART0 (USB port) and can be viewed via the serial monitor of the Arduino IDE. Make sure to adjust the primary MBUS address of the slave and the baud rate of the slave in the program.
