Xenon

A polished, all-in-one dashboard for the CORSAIR Xeneon Edge 14.5" LCD touchscreen — and any browser on Windows. Monitor your PC, control media and audio, mute your mic, manage your day, talk to a built-in AI assistant, drive your RGB lighting, and more — all from one glanceable screen.

Everything runs 100% locally: no cloud, no telemetry, no account required.

Built for the Xeneon Edge — great in any browser

Xenon is optimized for the CORSAIR Xeneon Edge 14.5" touchscreen: dense, glanceable tiles, comfortable touch targets, and a layout tuned for that display.

But it is just a local web app, so it works just as well in any Chromium-based browser (Edge, Chrome) on a normal monitor — touchscreen or not. Every control works with a mouse, and the layout reflows to fit landscape, portrait, large desktop windows, and the Xeneon Edge's short screen. Use it as a second-monitor dashboard, a browser tab, or an embedded panel in iCUE — same features everywhere.

Note: This is not a native iCUE widget. It runs as a tiny local Node.js server and is displayed inside iCUE via an iFrame. A native iCUE widget version is in development.

What's inside

A quick tour — see FEATURES.md for the full breakdown with screenshots.

• Customizable, multi-page dashboard — modular Bento grid with drag-and-drop layout, resizable tiles, tab-grouping, widget duplication, savable layout presets, and up to 8 pages.
• System & network monitor — CPU, GPU, RAM, disks, throughput, ping/jitter, and real in-game FPS (PresentMon).
• Media — now-playing from any SMTC app, transport controls, album art, per-source volume.
• Audio & microphone — output/input device pickers, master volume, mute, and a per-app mixer with real app icons.
• Xenon AI — a voice + vision + chat assistant that can control the whole dashboard. Runs on Google Gemini (cloud) or a free local provider (Ollama).
• Advanced AI features (opt-in) — Genesis (ask the AI to compose a dashboard page for you), Game Companion (in-game overlay with FPS, session time and AI screen insights), Guardian (PC health history with AI analysis — and viewable trend charts on the System tile), and Ambient presence (proactive greetings and alerts).
• RGB lighting bridge — drive Corsair/iCUE LEDs from real data (CPU temp, timers, volume, album art), coexisting with iCUE — plus network lights Govee, LIFX, WLED, Philips Hue and Nanoleaf (local, key-free).
• Deck — a programmable, Stream Deck-style key grid (apps, media, OBS, hotkeys, webhooks, soundboard, AI, and more).
• Productivity — calendar (with external Outlook/Google .ics sync), tasks, countdown timers, notes.
• Weather — current conditions, forecast, and an hourly timeline.
• Focus lock screen — a distraction-free overlay with clock, now-playing, events, and weather.
• Streaming — Twitch, YouTube, and OBS widgets and Deck actions.
• Remote PC control — turn your phone into a remote for your PC (Sunshine + Tailscale + Moonlight).
• Performance Mode — game mode auto-pauses ambient effects during full-screen play, plus on-demand, fully reversible system optimization (power plan, priority boost, closing background apps).
• App switcher — every open window at a glance, tap to focus, with favourite app shortcuts.
• Settings — Light/Dark/Auto theme, accent colours, ambient backgrounds, language (EN/IT/KO/JA/ZH), custom backgrounds, a cinematic daily greeting, optional auto-open at logon, and more.

Installation

Xenon runs as a small local Node.js server on http://127.0.0.1:3030/ and works in any browser. On the Xeneon Edge it is embedded in iCUE as an iFrame.

Step 1 — Run the installer (once)

1. Download the ZIP from Releases and extract it anywhere.
2. Open the extracted folder.
3. Double-click INSTALL.bat.
4. If Windows asks permission, click Yes (it needs admin rights for hardware sensors and the startup task).

The installer automatically:

• installs Node.js LTS if missing;
• installs FFmpeg if missing (so MP4 backgrounds can be converted for iCUE);
• installs LibreHardwareMonitor and PawnIO (CPU/disk temperature sensors);
• downloads PresentMon into server/presentmon/ (real in-game FPS counter);
• registers the server to start silently with Windows (no terminal, no tray icon);
• starts the server and opens http://127.0.0.1:3030/ so you can confirm it works.

The installer does not download the free local-AI components (Ollama / Whisper) — that keeps first-time setup fast. You set those up on demand from Settings → Xenon AI only if you switch to the local provider. See FEATURES.md.

Step 2 — Use it

In a browser (any monitor, touch or not): Just open http://127.0.0.1:3030/.

On the Xeneon Edge (via iCUE):

1. Open CORSAIR iCUE.

2. On your Xeneon Edge dashboard, add an iFrame widget.

3. Paste this tag and save:

   <iframe src="http://127.0.0.1:3030/" width="100%" height="100%" frameborder="0"></iframe>

   Size XL is recommended.

Every time you start your PC after that

Nothing. The server starts silently in the background and iCUE remembers your layout — the dashboard is live before you even open iCUE.

To remove the startup entry, double-click UNINSTALL.bat.

Requirements

• Windows 10 or 11 (x64)
• Node.js 18.15+ — installed automatically by INSTALL.bat
• FFmpeg — installed automatically; used for MP4 → WebM background conversion
• LibreHardwareMonitor + PawnIO — installed automatically; CPU/disk temperatures (degrades gracefully if absent)
• PresentMon — downloaded automatically; real in-game FPS (falls back to a DWM reading if unavailable)
• NirCmd — bundled; used for screen capture (Xenon AI vision)
• SoundVolumeView — bundled (NirSoft freeware, unmodified); audio device control

Optional:

• A free Gemini API key for Xenon AI (cloud) — everything else works without it.
• Ollama + Whisper.cpp for the free local AI provider — set up on demand from Settings.
• Sunshine + Tailscale for Remote Control — installed for you when you opt in; you use Moonlight on your phone.
• nvidia-smi is auto-detected for NVIDIA GPU usage/temperature.

Background videos in iCUE

iCUE's embedded WebView can reject some MP4 files even when they play fine in Chrome. Xenon handles this for you:

• Upload JPG, PNG, WebP, GIF, MP4, or WebM from Settings → Background media (up to 200 MB).

• When you upload an MP4, the server converts it to WebM (VP8, 30 FPS) when FFmpeg is available.

• If you run the server manually without FFmpeg, install it once:

  winget install --id Gyan.FFmpeg.Essentials --exact --source winget --accept-package-agreements --accept-source-agreements

  Then restart the server and re-upload the MP4. (Existing uploads are not converted retroactively.)

Troubleshooting

• node not recognised — install Node.js 18+ and reopen your terminal.
• Port 3030 already in use — close any other instance, or change the port in server/server.js.
• No CPU temperature — rerun INSTALL.bat and accept the admin prompt so it can install LibreHardwareMonitor/PawnIO and register the elevated startup task.
• Mic mute does nothing on first launch — wait a second or two; the device cache populates right after startup.

A note on AI assistance

This project was built with AI assistance throughout — architecture, code, debugging, and documentation. Every feature was designed, tested, and iterated on hands-on: the ideas, product direction, and every decision about what ships are mine. AI was a tool, not the author.
