Harmony with FLIRC Remote control Application

That application includes a systemd daemon that write all the inputs from a FLIRC USB Receiver to a pipe file located /var/run/flirc/flirc.pipe

That application will include a WebSocket that will read the pipe and send message events

A gui or console application will be created to read from that websocket and manage applications with the remote control using activities like Remote Buddy

Installation (Ubuntu LTS 24.04)

First install the flirc binaries (flirc_util, irtools) from https://flirc.com/ubuntu-software-installation-guide copying them into /usr/local/bin except for the appimage, the daemon uses flirc_util to check if the device is connected and to kick the device from bootloader when its power is interrupted.

Some extra packages are required to make it work (some packages have been renamed but its detected by apt)

sudo apt install libhidapi-hidraw0 libqt5core5a libqt5network5 libqt5xml5  libqt5xmlpatterns5 libhidapi-dev qtbase5-dev curl git

First, clone this repository

cd /tmp
git clone git@github.com:ngsoft/Harmony2404.git harmony
sudo mv harmony /opt
sudo chown -R $USER:$USER /opt/harmony
cd /opt/harmony
rm -rf .git
git init
git checkout -b main
git add .
git commit -m ":tada: first commit"

Some packages are required for the gui app to work, install them

sudo apt install xdotool evemu-tools

Some other packages can be installed if using gnome

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

Then install the service The package is auto installable on first execution

sudo /opt/harmony/usr/local/bin/flircd
sudo systemctl daemon-reload
sudo systemctl start flircd

InputLirc

We use a custom binary of inputlirc to capture the virtual keyboard InputLirc source code is located at lib/harmony/dist/inputlirc

Logs

Logs are located in these files

tail -f /var/log/flircd.log

tail -f /var/log/flircws.log

To read from the socket

sudo apt install netcat-traditional

nc -U /var/run/lirc/lircd

The websocket

If flircd is running a websocket is running on port 9030

ws://localhost.local:9030/ws

The gui

For the gui app I will use wails + svelte

sudo apt install build-essential libgtk-3-dev libwebkit2gtk-4.1-dev

On 24.04 Noble libwebkit2gtk-4.0-dev is not installable and that blocks the build process.

to fix that you need to modify /etc/apt/sources.list.d/ubuntu.sources

add jammy before noble

Types: deb
URIs: http://archive.ubuntu.com/ubuntu
Suites: jammy noble noble-updates noble-backports
Components: main universe restricted multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

## Ubuntu security updates. Aside from URIs and Suites,
## this should mirror your choices in the previous section.
Types: deb
URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security
Components: main universe restricted multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

then

sudo apt update
sudo apt install libwebkit2gtk-4.0-dev

then remove jammy from /etc/apt/sources.list.d/ubuntu.sources

sudo apt update
go install github.com/wailsapp/wails/v2/cmd/wails@latest

and wails will be working correctly (doctor will say libwebkit2gtk-4.0-dev is missing but wails dev and wails build will work correctly) to secure your package installation (preventing it to be removed, as of noble these packages are obolete, the risk is little)

sudo apt-mark hold libwebkit2gtk-4.0-dev
apt-mark showhold
