4. Live Mode — real-time data (continued)

Step 2 — Start Live

  1. Back on the dashboard, click the "● Live" button in the top bar.
  2. OHP Apex loads all passages of the session from the server (this may take a few seconds depending on data volume).
  3. The button turns ● Live green. The standings fill and update automatically every few seconds.

The "● Live" button active in green in the top bar, the standings filled with current times and animated positions

Warning

If the Live button stays grey or does not respond: verify that an event AND a session are selected in Settings. Without this selection, Live cannot start.

Changing session during the weekend

For example, switching from Qualifying to Race:

  1. Click ⚙️ to open Settings.
  2. In the "Session" list, select the new session (e.g. Race).
  3. Click "Save". OHP Apex automatically restarts Live with the new session.

Tip

No need to click Live again — changing the session in Settings automatically restarts the feed if Live was already active.

Stop Live

  1. Click "● Live" again. The button returns to grey. Data remains displayed but no longer updates.

Info

Resilience: after a network outage, missed passings are caught up automatically when the connection returns (a "Connection restored" toast confirms it). Race control messages and the flag history — which cannot be re-downloaded — are continuously saved to live_backup.json next to the application and restored when Live restarts on the same session.
