What Is Smart Dashboard?

Smart Dashboard is a web interface that runs inside a browser in fullscreen kiosk mode, presenting a clean, app-grid layout similar to a smart TV home screen. Behind the scenes, a Python/Flask backend handles launching desktop apps, executing system commands, and opening web URLs - all triggered by clicking icons on the dashboard.

The key idea: everything is treated like an app. Whether it's a Flatpak desktop application (Plex, Kodi, Jellyfin), a system command (shutdown, settings), or a web URL (Twitch, a local dashboard) - they all appear as icons on the grid and launch with a single click. Web URLs don't just open in a browser tab - they launch as sandboxed web apps in their own kiosk-style Brave instance, each with its own .config directory, window class, and scaling factor. This gives web apps the same fullscreen, immersive feel as native apps.

The dashboard itself is designed to always be running. It launches on boot/login via autostart and sits as your home screen. Attempting to close it (via Alt+F4 or otherwise) triggers a confirmation prompt, so accidental exits won't happen. When you launch an app, it appears on top of the dashboard - when you close that app, you're right back at the home screen.

Everything is configurable through plain JSON files and CSS:

• apps.json - define which apps appear, their icons, launch commands, and per-app scaling
• tools.json - define system actions in the toolbar (upper right), like shutdown, settings, or custom scripts
• weather.json - set your location and weather API key
• CSS - customize colors, layout, sizing, and appearance to your taste
• static/backgrounds/ - drop in your own wallpaper images; they're auto-detected and rotate every 5 minutes with a dissolve transition

Use Cases

Smart Dashboard is flexible enough for many scenarios:

• Media center PC - a TV-connected mini PC with Plex, Jellyfin, Kodi, and YouTube one click away
• Workplace dashboard - a wall-mounted display showing internal tools, dashboards, or informational kiosks
• Infotainment kiosk - a public-facing screen with curated apps and no way for users to escape to the desktop
• Repurposed hardware - give an old laptop or mini PC a second life as a dedicated appliance

If you can think of a use case, you just set the apps and tools you want, point it at the URLs or Flatpak apps you need, and let it run.

Features

• App Launcher - Click icons to launch Flatpak desktop apps (Plex, Jellyfin, Kodi, YouTube) or web apps (Twitch, custom URLs) that open as standalone kiosk windows via Brave
• Web App Management - Web apps launch in their own Brave instance with a unique window class, allowing the dashboard to cleanly close one web app before opening another
• Tools Panel - Quick access to system actions: Shutdown, Settings Manager, Input Remapper, and Close Dashboard
• Wallpaper Rotation - Automatically scans static/backgrounds/ for images and generates backgrounds.json at startup
• Weather Widget - Displays local weather using the OpenWeather API
• Kiosk Mode - The dashboard itself runs fullscreen in Brave kiosk mode, giving it the look and feel of a native smart TV interface
• Remote Friendly - Designed to work with FLIRC and input-remapper for IR remote or keyboard control; map a key to Alt+F4 to close web apps

How It Works

The UI runs in a web browser and uses Python and Flask to route

The Flask backend (server.py) serves the dashboard frontend and handles two main routes:

Route	Purpose
/	Renders the dashboard page with apps, tools, weather, and backgrounds
/launch?app=AppName	Launches a desktop app (Flatpak) or web app (Brave kiosk)
/tool?tool=ToolID	Executes a system tool/action

Web apps (URLs starting with http:// or https://) are launched using:

/usr/bin/brave-origin-stable --app="<url>" --kiosk --class=WebApp-<Name> --name=WebApp-<Name> --user-data-dir=<unique-dir> --force-device-scale-factor=<factor>

Each web app gets its own user data directory and window class, allowing the server to detect and cleanly terminate the previous web app before launching a new one.

Desktop apps are launched via their command (typically flatpak run ...).

System Requirements

8. Set Up Flatpak

flatpak remote-add --if-not-exists --user flathub https://dl.flathub.org/repo/flathub.flatpakrepo

9. Install Flatpak Apps

flatpak install --user flathub -y \
    com.github.tchx84.Flatseal \
    org.localsend.localsend_app \
    rocks.shy.VacuumTube \
    tv.kodi.Kodi \
    tv.plex.PlexHTPC \
    org.jellyfin.JellyfinDesktop

10. Install FLIRC (IR Remote Support)

curl apt.flirc.tv/install.sh | sudo bash

11. Clone and Set Up the Dashboard

mkdir ~/scripts
cd ~/scripts
git clone https://github.com/teklynk/smart-dashboard.git
cd smart-dashboard
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

12. Run the Dashboard

./run.sh

Always Run: You can use the run_always.sh script if you want the dashboard to re-open if it is closed. This will wait 3 seconds and launch the dashboard again. Great for when you absolutely do not want anyone to access to desktop.

The dashboard will be available at http://localhost:8080.

run.sh handles everything: generates backgrounds.json from images in static/backgrounds/, kills any existing instances, starts the Flask server, and launches Brave in kiosk mode pointing at the dashboard.

Configuration

apps.json

Defines the apps shown on the dashboard. Each entry includes:

Field	Description
name	Display name (used in the launcher route)
icon	Path to the icon image
command	Flatpak command for desktop apps, or a URL for web apps
force-device-scale-factor	Browser zoom factor for web apps (e.g. 1.25)

Desktop app example:

{
  "name": "Plex",
  "icon": "icons/plex.png",
  "command": "flatpak run tv.plex.PlexHTPC",
  "force-device-scale-factor": ""
}

Web app example:

{
  "name": "Twitch",
  "icon": "icons/twitch.png",
  "command": "https://twitchmultiview.teklynk.com",
  "force-device-scale-factor": "1.25"
}

tools.json

Defines quick-action tools accessible from the dashboard. Fields:

Field	Description
id	Unique identifier used in the /tool route
name	Display name
command	Shell command to execute
requires_confirmation	Whether the frontend should confirm before running
requires_sudo	(Currently informational; sudo is not prefixed)
icon	Path to the icon image

weather.json

{
  "zipCode": "90210",
  "apiKey": "YOUR_OPENWEATHER_API_KEY",
  "units": "imperial"
}

Replace the API key with your own from OpenWeather.

Backgrounds

Place wallpaper images (.jpg, .png, .gif, .webp) in static/backgrounds/. The run.sh script auto-generates backgrounds.json at startup.

Post-Install Setup

Desktop shortcut and Application menu entry

cp dashboard.desktop ~/.local/share/applications/

Configure Auto-Login (LightDM)

Edit the LightDM config:

sudo nano /etc/lightdm/lightdm.conf

Under [Seat:*], set:

[Seat:*]
autologin-user=yourusername
autologin-user-timeout=0

Auto-Start the Dashboard

Add run.sh to XFCE's Session and Startup:

1. Open Settings → Session and Startup
2. Go to the Application Autostart tab
3. Add a new entry pointing to the full path of run.sh

Also consider auto-starting unclutter (hides the mouse cursor when idle).

Install the Desktop Entry

mkdir -p ~/.local/share/applications
cp dashboard.desktop ~/.local/share/applications/

Configure Input Remapping

Use input-remapper-gtk to map remote or keyboard buttons. Map a key to Alt+F4 so web apps can be closed without a keyboard.

Important: Save your preset to your home directory and set it to auto-load on login.

Configure XFCE Panel

For a clean TV experience:

• Remove all panels except one (XFCE requires at least one panel to exist)
• Remove all panel applets
• Set panel transparency
• Set the panel to auto-hide

Disable Alt+Tab

• Open Settings Manager.
• Select Window Manager.
• Click the Keyboard tab.
• Find the Cycle windows action (often bound to Tab).
• Click on the shortcut and press Backspace to clear it, or press a new key combination to remap it.
• Click Close to save.

Prevent Sleep/Suspend

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Configure Firewall

sudo ufw allow from 192.168.0.0/24 to any proto tcp port 22
sudo ufw enable

Troubleshooting & Tips

Screen Locking on Wake

Method 1 - Power Manager GUI:

• Open Settings → Power Manager → Security tab
• Uncheck "Lock screen when system is going to sleep"
• Uncheck "Lock screen when system is idle"

Method 2 - Disable Screen Locker Autostart:

• Open Settings → Session and Startup → Application Autostart
• Uncheck Screen Locker (or light-locker / xfce4-screensaver)
• Reboot

Configure PulseAudio:

• Open pavucontrol (PulseAudio Volume Control)
• Go to the Configuration tab
• Set "Built-in Audio" profile to Digital Stereo (HDMI) Output
• Go to the Output Devices tab and set HDMI as the fallback device

Password Prompt on Auto-Login

If you are prompted to enter your password even though auto-login is enabled:

1. Open seahorse in the terminal
2. Delete current Login
3. Create a new keyring named Login (case-sensitive) with a blank password
4. Right-click it → Set as default
5. Reboot - the blank-password Login keyring will auto-unlock during auto-login

Navigation

Arrow keys will let you move through the main apps/icons.

Tab and Shift+Tab will let you access the Tool Bar apps/icons.

Alt+F4 will close most apps and web apps.
