MMDVMHost-Websocketboard

Introduction

This is a very first development version of my new MMDVMDash using websockets-technology to get rid of high load on Raspberry Pi and others and keep those temperature down.

Also this should improve user experience.

Technical Details

The Dashboard persists in detail in 3 components: two on the server (Hotspot/Repeater) side and on on the browser.

The two server sided components are the logtailer.py (which communicates via websocket with your browser and streams the logs to it for processing) and the webserver-component from python3 (which is serving the needed html and javascript infrastructure to your browser).

The client based component is the javascript processing the streamed log lines and filling the tables.

Used Ports

By default following Ports are used for running the Dashboard:

• 8000 TCP: webservice
• 5678 TCP: Websocket

Installation

You'll need to install several python3 modules. A concrete list will follow here later. Actually known:

• websockets: sudo apt install python3-websockets
• ansi2html: sudo pip3 install ansi2html
• gpiozero: sudo apt install python3-gpiozero
• psutil: sudo apt install python3-psutil

Recommendations

• take care to set Loglevel for FileLevel = 2 in your MMDVM.ini
• also set debug = 0 on each section to avoid irritating output on the Dashboard
• Python3.7 at least must be instaled

Installation steps

• clone this repository to your home-directory with git clone --recurse-submodules -j8 https://github.com/dg9vh/MMDVMHost-Websocketboard to clone the repository with it's submodules
• create directory with sudo mkdir /opt/MMDVMDash
• change ownership to your user for example with sudo chown -R pi /opt/MMDVMDash
• copy all files from repository into this folder
• modify logtailer.ini to fit your needs
• modify /html/js/config.js to fit your needs, here you can switch on/off tabs showing or enable debug for getting some output in javascript console. You should take a look into this file - here are different options you can configure.
• copy files in /opt/MMDVMDash/systemd to /etc/systemd/system or similar corresponding to your system
• modify both scripts to fit your needs
• enable services with following commmands, this results in starting both automatically after reboot:
  • sudo systemctl enable http.server.service
  • sudo systemctl enable logtailer.service
• start services with following commmands:
  • sudo systemctl start http.server.service
  • sudo systemctl start logtailer.service

Finally you should be able to get the new Dashboard calling the hostname of your hotspot and port 8000 (default) in your broser

Troubleshoting

If you have any trouble running the software most things depend on the logtailer-component. So it is a good idea to try starting the software on the console wih python3 ./logtailer.py to see the output of the programme. A common error are missing python-libraries you should install with the commands mentioned above.

If you found any further missing library let me know! Just open an issue!

If there are problems with paths for logfiles you also could get some impressions with the output of the programme.

If using DMRHost by BrandMeister-Team

If you are using the DMRHost as replacement for MMDVMHost you should enable DMR-ID-Lookup within logtailer.ini by setting the corresponding option = 1 Also take care to configure the filepath to the correct location of your DMRIds.dat.

For updating the DMRIds.dat you can use the script you find in scripts-folder.
