# MBus

[![Clojars

Project](https://img.shields.io/clojars/v/io.helins/mbus.svg)](https://clojars.org/io.helins/mbus)

[![Cljdoc](https://cljdoc.org/badge/io.helins/mbus)](https://cljdoc.org/d/io.helins/mbus)

Thin clojure wrapper around [JMbus](https://www.openmuc.org/m-bus/) for

communicating with [Meter-Bus](https://en.wikipedia.org/wiki/Meter-Bus) slave

devices.

Supports a (very) wide variety of platforms.

## Installation

This library needs [jRxTx](https://github.com/openmuc/jrxtx) for using serial

ports. For instructions, you can also refer to

[helins/rxtx](https://github.com/helins/rxtx), our own clojure wrapper.

## Usage

This is just a very brief overview.

The [full API is available on Cljdoc](https://cljdoc.org/d/io.helins/mbus).

In short :

```clj

(require '[helins.mbus       :as mbus]

         '[helins.mbus.wired :as mbus.wired])

(with-open [connection (mbus.wired/serial-connection "/dev/ttyUSB0"

                                                     {:mbus/timeout   1000

                                                      :mbus/baud-rate 2400})]

  

  ;; Request user data (ie. a variable data structure) from slave 0

  (mbus.wired/req-ud2 connection

                      0))

```

## Status

For the time being, if you need wireless M-Bus, you need to interop with

[JMbus](https://www.openmuc.org/m-bus/).
