Work In Progress

This daemon should provide basic functionality with mqtt-json context and currently undergoes test.
It will publish all data received from the RepRap web-api without modifications to the specific MQTT server/Service

Installation

On a modern Linux system just a few steps are needed to get the daemon working. The following example shows the installation under Debian/Raspbian below the /opt directory:

sudo apt install git python3 python3-pip bluetooth bluez

git clone https://github.com/Nightreaver/RRF_WebIF_MQTT.git /opt/rrf-mqtt-daemon

cd /opt/rrf-mqtt-daemon
sudo pip3 install -r requirements.txt

Configuration

To match personal needs, all operation details can be configured using the file config.ini. The file needs to be created first:

cp /opt/rrf-mqtt-daemon/src/config.{ini.dist,ini}
vim /opt/rrf-mqtt-daemon/src/config.ini

Attention: You need to add at least one RRF printer to the configuration.

Execution

A first test run is as easy as:

python3 /opt/rrf-mqtt-daemon/src/service.py

With a correct configuration the result should look similar to the the screencap above.

Using the command line argument --config, a directory where to read the config.ini file from can be specified, e.g.

python3 /opt/rrf-mqtt-daemon/src/service.py --config /opt/rrf-mqtt-daemon

The extensive output can be reduced to error messages:

python3 /opt/rrf-mqtt-daemon/src/service.py > /dev/null

Continuous Daemon/Service

You most probably want to execute the program continuously in the background. This can be done either by using the internal daemon or cron.

Attention: Daemon mode must be enabled in the configuration file (default).

1. Systemd service - on systemd powered systems the recommended option

   sudo cp /opt/rrf-mqtt-daemon/template.service /etc/systemd/system/rrfd.service
   
   sudo systemctl daemon-reload
   
   sudo systemctl start rrfd.service
   sudo systemctl status rrfd.service
   
   sudo systemctl enable rrfd.service

2. Screen Shell - Run the program inside a screen shell:

   screen -S rrf-mqtt-daemon -d -m python3 /path/to/rrf-mqtt-daemon/src/service.py
