openf1-console 1.0.12

open-f1

open-f1 is a open source Live Timing client which integrates with the F1 Live Timing data stream. The client allows you to receive live data during F1 sessions. This data can be streamed in to a file for later processing, or processed live to show in live timing clients.

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.

openf1-console is a TUI application which uses OpenF1.Data to show a basic Live Timing screen during sessions.

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.

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 [S] Session Screen
3. Start a Live Session with the [L] Start Live Session action.
4. Press [Esc] to return to the main screen
5. Switch to the Timing Tower screen with the [O] Timing Tower action

Start Timing for a Pre-recorded Session

1. Start openf1-console as described above
2. Navigate to the [S] Session Screen
3. Start a Simulated Session with the [F] Start Simulation action.
4. Select the session to start using the Up/Down arrows, then pressing [Enter]
5. Press [Esc] to return to the main screen
6. Switch to the Timing Tower screen with the [O] Timing Tower action

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 [►] Delay+ and [◄] 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 [◄] Delay- action to fast-forward through the session.

Using the Cursor

There is a global cursor that is controlled with the [▼] Down (1) and [▲] 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.

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

The following topics are also available but currently not subscribed to:

• CarData.z
• Position.z

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 Interval for a Specific Driver

Use the cursor controlled by the [▼] Down (1) and [▲] Up actions in the [O] 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.
