Timing Sensors

:::tip 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.

    IDLE: ⏸️ IDLE<br/><small>No active period</small>
    ACTIVE: ▶️ ACTIVE<br/><small>In period</small>
    GRACE: ⏳ GRACE<br/><small>60s buffer</small>

    IDLE --> ACTIVE: period starts
    ACTIVE --> GRACE: period ends
    GRACE --> IDLE: 60s elapsed
    GRACE --> ACTIVE: new period starts<br/><small>(within grace)</small>

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
