# 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.
|
|
|
|
## Key Features
|
|
* Websockets for reducing load on the hotspot/repeater
|
|
* Currently TXing on all timeslots
|
|
* Last-Heard-List
|
|
* QSO-net-management
|
|
* Local Heard-List
|
|
* DAPNET messages with decoding of Skyper-messages, -rubrics and METAR-messages
|
|
* System-Info-panel for visualize system health
|
|
* Automatically detecting clients timezone for displaying timestamps in local behavior
|
|
* Easier to customize the html-page because client-part persists in html and javascript-files
|
|
|
|
## 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.
