open-f1

open-f1 is a open source F1 Live Timing client.

openf1-console is a TUI application which uses OpenF1.Data to show a Live Timing screen during sessions, and records the data for future session replays.

The OpenF1.Data library is provided to facilitate connectivity with the F1 Live Timing data stream, and handle all the processing of the incoming data. It also allows for "simulated" streams, where previously recorded data streams can be played back to allow for easy development/testing.

Feature Highlights:

  • Timing Tower showing for each driver:
    • Live sector times, with colouring for personal/overall fastest
    • Last & Best Lap
    • Current tyre
    • Age of current tyre
    • Interval to driver in front
    • Gap to leader
    • Gap between a selected driver and all other drivers (useful for monitoring pit windows)
  • Race Control messages including investigations, penalties, lap deletions, and weather
  • Lap-by-lap Timing History to observe gaps over time

Inspiration

This project is heavily inspired by the FastF1 project by theOehrly. They did a lot of the work understanding the SignalR stream coming from the F1 Live Timing service. Visit their project if you'd like to do any sort of data analysis on past F1 events, or gather live timing data using their module.

Getting Started with openf1-console

Installation

Install and run as a dotnet tool

openf1-console is available as a dotnet tool from NuGet, which means it can be installed system-wide simply by running:

# Install globally using the -g flag
dotnet tool install -g openf1-console

# Assuming the dotnet tools directory is on your path, simply execute openf1-console
openf1-console

This method is recommended as it is easy to keep the app updated using dotnet tool update -g openf1-console.

Install and run the standalone executable

Standalone executables are attached to each GitHub release. Download the executable for your system OS/architecture and simply run it directly

# Download the latest executable (in this case for macos-arm64)
curl https://github.com/BrownKnight/open-f1/releases/latest/download/openf1-console-macos-arm64 -o ./openf1-console -L

# On MacOS, you'll likely need to sign the executable as otherwise it'll be blocked. 
# WARNING: If you don't understand why this needs to be done, you probably shouldn't do this and instead use the NuGet based installation method above.
#          Signing the executable yourself removes any integrity checks that signing usually provides.
codesign -s - ./openf1-console

# Execute openf1-console to start the TUI
./openf1-console
Run directly from Source
# Checkout the git repository
git clone git@github.com:BrownKnight/open-f1.git

# Run the console project with `dotnet run`
dotnet run --project OpenF1.Console/OpenF1.Console.csproj

Start Timing for a Live Session

  1. Start openf1-console as described above
  2. Navigate to the <kbd>S</kbd> Session Screen
  3. Start a Live Session with the <kbd>L</kbd> Start Live Session action.
  4. Press <kbd>Esc</kbd> to return to the main screen
  5. Switch to the Timing Tower screen with the <kbd>O</kbd> Timing Tower action

During the session, streamed timing data will be written to ~/open-f1/data/<session-name>. This will allow for future replays of this recorded data.

Start Timing for a Pre-recorded Session

Data for pre-recorded sessions should be stored in the ~/open-f1/data/<session-name> directory. Sample data can be found in this repos Sample Data folder. To use this sample data, copy one of the folders to ~/open-f1/data and then it will be visible in step 4 below.

  1. Start openf1-console as described above
  2. Navigate to the <kbd>S</kbd> Session Screen
  3. Start a Simulated Session with the <kbd>F</kbd> Start Simulation action.
  4. Select the session to start using the Up/Down arrows, then pressing <kbd>Enter</kbd> `
  5. Press <kbd>Esc</kbd> ` to return to the main screen
  6. Switch to the Timing Tower screen with the <kbd>O</kbd> Timing Tower action
  7. Optionally skip forward in time a bit by decreasing the delay with <kbd>←</kbd> (or <kbd>⇧ Shift</kbd> + <kbd>←</kbd> to decrease by 30 seconds).

During the Session

Managing Delay

All session data, whether live or pre-recorded, is sent to a Channel that acts as a delayed-queue. After a short delay, data points are pulled from the queue and processed, leading to updates on the timing screens. The amount of this delay can be changed with the <kbd>►</kbd> Delay+ and <kbd>◄</kbd> Delay- actions whilst on the timing screens. When using openf1-console during a live session, you may wish to increase this delay to around ~50 seconds (actual number may vary) to match with the broadcast delay and avoid being spoiled about upcoming action.

Simulated session start with a calculated delay equal to the amount of time between the start of the actual session and now. This means you can decrease the delay with the <kbd>◄</kbd> Delay- action to fast-forward through the session.

Using the Cursor

There is a global cursor that is controlled with the <kbd>▼</kbd> Down (1) and <kbd>▲</kbd> Up actions. What this cursor does depends on the screen, for example is can be used in the Timing Tower screen to scroll through Race Control Messages, or to select a driver on the Tower to see comparative intervals.

Configuration

OpenF1 can be configured using a simple config.json file, or using environment variables. JSON configuration will be loaded from ~/open-f1/config.json.

Name JSON Path Environment Variable Description
Data Directory dataDirectory OPENF1_DATADIRECTORY The directory in which JSON timing data is read or written from

Live Timing Data Source

F1 live timing is streamed using SignalR (the old ASP.NET version, not the newer ASP.NETCore protocol) at https://livetiming.formula1.com/signalr. The OpenF1.Data simply connects to this endpoint, subscribes to the "Streaming" Hub, and listens for messages. It subscribes to the following "topics":

  • Heartbeat
  • ExtrapolatedClock
  • TopThree
  • TimingStats
  • TimingAppData
  • WeatherData
  • TrackStatus
  • DriverList
  • RaceControlMessages
  • SessionInfo
  • SessionData
  • LapCount
  • TimingData
  • CarData.z
  • Position.z
  • ChampionshipPrediction
  • TeamRadio

Data Recording and Replay

All events received by the live timing client will be written to the configured Data Directory, see see Configuration for details. Files will be written to a subdirectory named using the current sessions name, e.g. ~/open-f1/data/Jeddah_Race/. In this directory, two files will be written:

  • subscribe.txt contains the data received at subscription time (i.e. when the live timing client connected to the stream)
  • live.txt contains an append-log of every message received in the stream

Both of these files are required for future simulations/replays. The IJsonTimingClient supports loading these files and processing them in the same way live data would be. Data points will be replayed in real time, using a calculated delay.

Using a Cursor to Display Relative Gap for a Specific Driver

Use the cursor controlled by the <kbd>▼</kbd> Down (1) and <kbd>▲</kbd> Up actions in the <kbd>O</kbd> Timing Tower screen to select a specific driver (in this case Norris) to see the relative interval between that driver and all other. This is useful for determining where a driver will fall to after a pit stop, or looking at pit windows during under cuts.

Additionally, the gap between the selected drivers and those around them over the last four laps will be displayed at the bottom of the screen. This allows you to easily see evolving gaps over time and evaluate how soon a driver may catch up or pull away.

Using a Cursor to View Timing History by Lap

In the <kbd>H</kbd> Timing by Lap screen, you can use the cursor controlled by the <kbd>▼</kbd> Down (1) and <kbd>▲</kbd> Up actions to view historical snapshots of the timing tower at the end of every lap. This view will show position changes during that lap, and relative changes in Gap and Interval. Scrolling through laps allows you to build a picture of how the race is unfolding.
