Session Time Remaining
Time remaining in the current session (beta). Use sensor.f1_session_time_remaining 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_remaining - How much scheduled session time is left, based on the F1 ExtrapolatedClock feed. Like the elapsed sensor, this value follows the available clock data and its running flag. Check clock_running and clock_phase rather than assuming every interruption pauses the clock.
State
- String: remaining time formatted as
H:MM:SS(e.g.,0:36:15), orunavailablewhen no data is available.
Example
0:36:15

The session clock counts down the scheduled duration of the session. It does not account for race laps — in a race, the session ends when the leader completes the required number of laps, which may happen before or (rarely) after the scheduled time expires. Use sensor.f1_race_lap_count for lap-based progress.
