ebusd - eBUS daemon
|
|
===================
|
|
|
|
ebusd is a daemon for handling communication with eBUS devices connected to a
|
|
2-wire bus system ("energy bus" used by numerous heating systems).

Features
|
|
--------
|
|
|
|
The main features of the daemon are:
|
|
|
|
* use one of these device connections:
|
|
* serial (via USB or integrated UART)
|
|
* TCP
|
|
* UDP
|
|
* enhanced ebusd protocol allowing arbitration to be done directly by the hardware, e.g. for recent
|
|
* [ebus adapter 5](https://adapter.ebusd.eu/v5/), or
|
|
* [ebusd-esp firmware](https://github.com/john30/ebusd-esp/)
|
|
* actively send messages to and receive answers from the eBUS
|
|
* passively listen to messages sent on the eBUS
|
|
* regularly poll for messages
|
|
* cache all messages
|
|
* scan for bus participants and automatically pick matching message configuration files from config web service at ebusd.eu (or alternatively local files)
|
|
* parse messages to human readable values and vice versa via message configuration files
|
|
* automatically check for updates of daemon and configuration files
|
|
* pick preferred language for translatable message configuration parts
|
|
* grab all messages on the eBUS and provide decoding hints
|
|
* log messages and problems to a log file
|
|
* capture messages or sent/received bytes to a log file as text
|
|
* dump received bytes to binary files for later playback/analysis
|
|
* listen for [command line client](3.1.-TCP-client-commands) connections on a dedicated TCP port
|
|
* provide a rudimentary HTML interface
|
|
* format messages and data in [JSON on dedicated HTTP port](https://github.com/john30/ebusd/wiki/3.2.-HTTP-client)
|
|
* publish received data to [MQTT topics](https://github.com/john30/ebusd/wiki/3.3.-MQTT-client) and vice versa (if authorized)
|
|
* announce [message definitions and status by MQTT](https://github.com/john30/ebusd/wiki/MQTT-integration) to e.g. integrate with [Home Assistant](https://www.home-assistant.io/) using [MQTT Discovery](https://www.home-assistant.io/docs/mqtt/discovery/)
|
|
* support MQTT publish to [Azure IoT hub](https://docs.microsoft.com/en-us/azure/iot-hub/) (see [MQTT integration](https://github.com/john30/ebusd/wiki/MQTT-integration))
|
|
* act as a [KNX device](https://github.com/john30/ebusd/wiki/3.4.-KNX-device) by publishing received data to KNX groups and answer to read/write requests from KNX, i.e. build an eBUS-KNX bridge
|
|
* [user authentication](https://github.com/john30/ebusd/wiki/3.1.-TCP-client-commands#auth) via [ACL file](https://github.com/john30/ebusd/wiki/2.-Run#daemon-options) for access control to certain messages

Installation
|
|
------------
|
|
|
|
Either pick the [latest release package](https://github.com/john30/ebusd/releases/latest) suitable for your system,
|
|
use the Debian repository as [described here](https://github.com/john30/ebusd-debian/blob/master/README.md),
|
|
use `makepkg` for [Archlinux](https://github.com/john30/ebusd/tree/master/contrib/archlinux)
|
|
or pick the [package from the Alpine Linux repository](https://pkgs.alpinelinux.org/package/edge/community/x86/ebusd),
|
|
build it yourself, or use a docker image (see below).
|
|
|
|
Building ebusd from the source requires the following packages and/or features:
|
|
* autoconf (>=2.63) + automake (>=1.11) or cmake (>=3.7.1)
|
|
* g++ with C++11 support (>=4.8.1)
|
|
* make
|
|
* kernel with pselect or ppoll support
|
|
* glibc with argp support or argp-standalone
|
|
* libmosquitto-dev for MQTT support
|
|
* libssl-dev for SSL support
|
|
|
|
To start the build process, run these commands:
|
|
> ./autogen.sh
|
|
> make install-strip
|
|
|
|
Or alternatively with cmake:
|
|
> cmake .
|
|
> make install/strip
|

Documentation

Configuration
|
|
-------------
|
|
|
|
The most important part of each ebusd installation is the message configuration.
|
|
Starting with version 3.2, **ebusd by default uses the config web service at ebusd.eu to retrieve
|
|
the latest configuration files** that are reflected by the configuration repository (follow the "latest" symlink there):
|
|
> https://github.com/john30/ebusd-configuration
|
|
|
|
|
|
Docker image
|
|
------------
|
|
|
|
A multi-architecture Docker image using the config web service for retrieving the latest message configuration files is available on the hub.
|
|
You can use it like this:
|
|
> docker pull john30/ebusd
|
|
> docker run -it --rm --device=/dev/ttyUSB0 -p 8888 john30/ebusd
|
|
|
|
For more details, see [Docker Readme](https://github.com/john30/ebusd/blob/master/contrib/docker/README.md).
