# Arduino-MBUS-Meter

This is an example for Arduino IDE how to create an own MBUS consumption meter (MBUS Slave) for Arduino MKR boards, Raspberry Pi Pico and Feather Boards (including ESP32, RP2040, nRF52840, Cortex M0 ....).

![Data output of the simulated meter in Lorusfree](https://user-images.githubusercontent.com/3049858/263453247-d6c13182-0374-48ee-8505-16257cd2addd.jpg)

## Hardware

I've used our MBUS Slave boards:

MBUS Slave Arduino MKR Shield:

The code was tested with the following boards:

* Arduino MKR Wifi 1010
* Adafruit Feather Huzzah32
* Adafruit Feather nRF52840
* Adafruit Feather M0 Express
* Sparkfun ESP32 Thing Plus
* Sparkfun Thing Plus RP2040
* Raspberry Pi Pico

Furthermore, an MBUS master is required to supply the MBUS and to be able to exchange data with the slave. For example, you can use a [Raspberry Pi with libmbus and our MBUS Master HAT](https://www.hwhardsoft.de/english/projects/m-bus-rpi-hat/)....

## Remarks

The default baud rate, default bus address and id of the device can be adjusted in mbusslave.h.

Consumption values can be added or edited in the Encode_Payload() function. Be careful with MBUS codes of the "Device" domain. This code does not work or is already contained in the header of the protocol.

You can view the structure of the header in mbusslave.cpp and change parameters, e.g. the manufacturer ID, if necessary.

## Libraries

Install the following library through Arduino Library Manager
