Live Timing, Race Control & GHCR

[adn8naiagent]

1.2.0 - 2026-03-14

New Features

• Live Timing - real-time timing data via F1 SignalR stream, with broadcast delay slider, post-session replay check, and PiP window support
• Race Control Messages - live feed of steward decisions, investigations, penalties, track limits, and flag changes accessible via the RC button on the track map (available in both live and replay modes)
• Driver Indicators - investigation (warning triangle) and penalty (circled exclamation) icons on the leaderboard, with automatic clearing when stewards resolve incidents

Improvements

• Broadcast delay slider now persists - your delay setting is saved and restored across page loads, so you only need to set it once to match your streaming service or broadcast feed
• Docker images published to GHCR - pre-built images are now automatically published to GitHub Container Registry on each release, so users can deploy with just a docker-compose.yml without cloning the repo
• PiP window track map and driver positions now continue updating when switching windows (contributed by @Clav3rbot)
• Session picker shows session start times in the user's local timezone (contributed by @Clav3rbot)
• Improved Docker Compose configuration with clearer comments on port and URL customisation

Known Limitations

• Live timing: no track positions or telemetry - Driver positions on the track map and telemetry data are not available during live sessions. Position data requires an authenticated F1 TV subscription. Full track positions and telemetry become available in replay mode once session data is processed (typically 1–2 hours after the session).

Note

• Race control messages in replay mode require a re-run of precompute for each session to take effect.
• Best lap time and gap to leader columns for practice/qualifying require a re-run of precompute for existing sessions. Live sessions work immediately.

Thanks for your work on this. I tried it at the weekend and it was a good first impression.

Is it possible to get lap time data please? Last lap time per driver is the main thing missing in my opinion. It's fairly essential information to follow and understand the race imo - it's why I like to have the timing on a second screen in the first place. The gaps alone aren't sufficient as it's about keeping an eye on underlying pace and seeing how it compares between drivers and changes through a stint. More of a "live timing" table and a smaller track map would be great. The track map is only really relevant in race sessions when it comes to pitstop gaps and lapping later in the race,

I think lap time are available in the free tier of F1TV live timing. It would be awesome if you could click a driver and see a lap by lap, laptime history/progression to that point in the race.

Sector times are certainly a nice to have but not so important if difficult or simply unavailable without a F1TV license.

Having used F1 Multiviewer, the other thing I really miss is the speech to text translation of radio messages. Again I imagine that requires a license but if the data is available anywhere that also adds a lot as it fills in things the tv coverage often misses.

Thanks for the great suggestions. In the latest version I have added a column on the leaderboard for last lap time per driver.

Have also added a new lap analysis panel where you can select two drivers to see all of their lap times compared, including a simple line chart. I had a look at sector times but I think it was all going to become a bit too cluttered. If I can think of a way to add it in future I will.

For Team Radio, these are available with Fast F1 without subscription. Haven't had a chance to implement this yet, but I'll have a look at how we can pull this out with transcripts.

Deleted this and move comment to the v1.3 thread as seemed better there.

Thank you for a fantastic app! I'm looking forward to the next race.
Does the telemetry provider offer the battery information? This has become one of the most important factors this season.

[adn8naiagent]

Thanks for checking it out and glad you're enjoying it!

Unfortunately, from everything I've been able to find, battery information is not being shared by the teams at all, whether through Fast F1 or through direct F1 signalR or any other source.

Would love to be able to include at least battery level, if not Regen and Deploy, and where overtaking or boost is available. It's a big gap now that there's no DRS and the battery seems essential for overtaking or defending.

I'm going to continue to check each weekend to see if this data starts becoming available, and when it is, we'll definitely be adding it to telemetry.

Hey thanks for this! Found this in time today and set it up for the race. is there any way to get driver position data during a race? This would be amazing. Cheers!

[adn8naiagent]

Unfortunately the live SignalR feed from F1 gates the on track position and telemetry data behind their paywall. Each user would need an F1TV subscription and to auth in to make it work which I think is clunky. The data is available from FastF1 but only for replays

[bjain102]

Gotcha. Thanks for the information! It would have been great otherwise, though.🥲
