SETUP

Three steps. That's it.

01

Discover your lights

Open the app, go to Lights, and hit Discover. Your LIFX and Nanoleaf devices appear automatically. Select the ones you want.

02

Enable UDP telemetry in F1 25 or F1 24

Settings → Telemetry Settings. Set UDP to On, point it at your PC's local IP, your chosen port (20777 by default).

03

Start the bridge

Hit Start Bridge. From that moment on, every race event fires your lights automatically — whether you're watching or racing.

SUPPORTED DEVICES

LIFX. Nanoleaf. Philips Hue.

Nanoleaf

Canvas, Shapes, Lines, Elements, Light Panels. The Panel Layout UI maps the start lights sweep to your physical panel arrangement on the wall.

  • Position-based sweep
  • Local REST API — no cloud

Philips Hue

Bulbs and Gradient Lightstrip Plus, all running over your home network — no internet required. The Gradient Lightstrip fills up segment by segment during the start lights sequence, matching the on-screen countdown light by light.

  • Gradient Lightstrip — segment sweep
  • Hue Bridge on your network
  • No cloud, no subscription

FEATURES

Everything you need.
Nothing you don't.

Sub-second latency

Direct LAN. No cloud relay, no subscription, no middleman. The light fires when the event fires.

Profiles

Save your entire setup — lights, effects, brightness, idle colour — and switch between them instantly.

Light Assignment

Full per-effect control. Assign specific lights to specific events. Yellow flag in one room, start lights in another.

Multizone sweep

Start lights fill zones left-to-right across your LIFX strip, one by one, matching the real on-screen sequence.

Panel Layout UI

Drag your Nanoleaf panels to match your physical wall. The sweep follows your layout — not the API's arbitrary order.

UDP Forwarding

Relay telemetry to a second destination simultaneously. Sim dashboard software, second PC — your call.

Ready for another layer of immersion?

Free. Open source. Runs entirely on your local network.
