Session Time Elapsed
Time elapsed in the current session (beta). Use sensor.f1_session_time_elapsed in dashboards, templates, and automations.
See live data availability for session and data-source requirements. The details below describe any additional conditions for this entity.
These are standard entity IDs. If Home Assistant assigned a different ID, or you renamed an entity, use your existing ID in the examples.
State and attributes
This sensor is currently in beta. The behavior has not been verified across all session types, edge cases (red flags, suspensions, qualifying segments), and timing scenarios. Treat the values as indicative rather than definitive until further testing is complete.
sensor.f1_session_time_elapsed - How much of the scheduled session time has passed, based on the F1 ExtrapolatedClock feed. The value follows the available session clock and its running flag. A Safety Car alone does not imply that this clock pauses; check clock_running and clock_phase.
State
- String: elapsed time formatted as
H:MM:SS(e.g.,0:23:45), orunavailablewhen no data is available.
Example
0:23:45
