Timing Sensors

Entity ID tip

<home_name> is a placeholder for your Tibber home display name in Home Assistant. Entity IDs are derived from the displayed name (localized), so the exact slug may differ. Can't find a sensor? Use the Entity Reference (All Languages) to search by name in your language.

Timing sensors provide real-time information about Best Price and Peak Price periods: when they start, end, how long they last, and your progress through them.

Enlarge

IDLE = waiting for next period (shows countdown via next_in_minutes). ACTIVE = inside a period (shows progress 0–100% and remaining_minutes). GRACE = short buffer after a period ends, allowing back-to-back periods to merge seamlessly.

Available Timing Sensors

For each period type (Best Price and Peak Price):

Sensor	When Period Active	When No Active Period
End Time	Current period's end time	Next period's end time
Period Duration	Current period length (minutes)	Next period length
Remaining Minutes	Minutes until current period ends	0
Progress	0–100% through current period	0
Next Start Time	When next-next period starts	When next period starts
Next In Minutes	Minutes to next-next period	Minutes to next period

"Unknown" during an active period is normal

While a period is active, Next Start Time and Next In Minutes look for the period after the current one. If no further period exists (for example, because tomorrow's prices are not published yet), there is nothing to show and both sensors report "Unknown". The same applies to the Peak Price counterparts. They fill in automatically once a further period is found. See Troubleshooting.
