# Sensors Overview > **Tip:** Many sensors have dynamic icons and colors! See the **[Dynamic Icons Guide](dynamic-icons.md)** and **[Dynamic Icon Colors Guide](icon-colors.md)** to enhance your dashboards. :::tip Entity ID tip `` 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)](sensor-reference.md)** to search by name in your language. ::: The integration provides **100+ sensors** organized by purpose. This page gives a quick overview and links to detailed guides for each sensor family. | Sensor Family | Purpose | Guide | |---|---|---| | **Binary Sensors** | Period on/off indicators | [below](#binary-sensors) | | **Core Price** | Current, next, previous interval prices | [below](#core-price-sensors) | | **Average & Statistics** | Daily averages, rolling averages, median/mean | [Average Sensors](sensors-average.md) | | **Ratings & Levels** | Price classification (3-level ratings, 5-level API levels) | [Ratings & Levels](sensors-ratings-levels.md) | | **Min/Max** | Daily and rolling 24h extremes | [below](#minmax-sensors) | | **Volatility** | Price fluctuation analysis | [Volatility Sensors](sensors-volatility.md) | | **Trends** | Price outlook, trajectory, direction | [Trend Sensors](sensors-trends.md) | | **Timing** | Period countdown, progress, duration | [Timing Sensors](sensors-timing.md) | | **Energy & Tax** | Spot price and tax breakdown | [Energy & Tax](sensors-energy-tax.md) | | **Diagnostic** | Chart metadata, data export | [below](#diagnostic-sensors) | --- ## Binary Sensors ### Best Price Period & Peak Price Period These binary sensors indicate when you're in a detected best or peak price period. See the **[Period Calculation Guide](period-calculation.md)** for a detailed explanation of how these periods are calculated and configured. **Quick overview:** - Best Price Period: Turns ON during periods with significantly lower prices than the daily average - Peak Price Period: Turns ON during periods with significantly higher prices than the daily average Both sensors include rich attributes with period details, intervals, relaxation status, and more. ## Core Price Sensors The integration provides price sensors for the **current**, **next**, and **previous** 15-minute interval. Each exposes the total price as sensor state, with `energy_price` and `tax` available as attributes (see [Energy & Tax Breakdown](sensors-energy-tax.md)). **Next N Hours Average** sensors (`next_avg_1h`–`next_avg_12h`) provide future price forecasts for 1h, 2h, 3h, 4h, 5h, 6h, 8h, and 12h windows. For detailed average sensor behavior (median vs mean, configuration, automation examples), see **[Average & Statistics Sensors](sensors-average.md)**. ## Min/Max Sensors These sensors show the lowest and highest prices for calendar days and rolling windows: ### Daily Min/Max | Sensor | Description | |--------|-------------| | Today's Lowest Price | Minimum price today (00:00–23:59) | | Today's Highest Price | Maximum price today (00:00–23:59) | | Tomorrow's Lowest Price | Minimum price tomorrow | | Tomorrow's Highest Price | Maximum price tomorrow | ### 24-Hour Rolling Min/Max | Sensor | Description | |--------|-------------| | Trailing Price Min | Lowest price in the last 24 hours | | Trailing Price Max | Highest price in the last 24 hours | | Leading Price Min | Lowest price in the next 24 hours | | Leading Price Max | Highest price in the next 24 hours | ### Key Attributes All min/max sensors include: | Attribute | Description | |-----------|-------------| | `timestamp` | When the extreme price occurs/occurred | | `price_diff_from_daily_min` | Difference from daily minimum | | `price_diff_from_daily_min_%` | Percentage difference | ## Diagnostic Sensors ### Chart Metadata **Entity ID:** `sensor._chart_metadata` > **✨ New Feature**: This sensor provides dynamic chart configuration metadata for optimal visualization. Perfect for use with the `get_apexcharts_yaml` action! This diagnostic sensor provides essential chart configuration values as sensor attributes, enabling dynamic Y-axis scaling and optimal chart appearance in rolling window modes. **Key Features:** - **Dynamic Y-Axis Bounds**: Automatically calculates optimal `yaxis_min` and `yaxis_max` for your price data - **Automatic Updates**: Refreshes when price data changes (coordinator updates) - **Lightweight**: Metadata-only mode (no data processing) for fast response - **State Indicator**: Shows `pending` (initialization), `ready` (data available), or `error` (service call failed) **Attributes:** - **`timestamp`**: When the metadata was last fetched - **`yaxis_min`**: Suggested minimum value for Y-axis (optimal scaling) - **`yaxis_max`**: Suggested maximum value for Y-axis (optimal scaling) - **`currency`**: Currency code (e.g., "EUR", "NOK") - **`resolution`**: Interval duration in minutes (usually 15) - **`error`**: Error message if service call failed **Usage:** The `tibber_prices.get_apexcharts_yaml` action **automatically uses this sensor** for dynamic Y-axis scaling in `rolling_window` and `rolling_window_autozoom` modes! No manual configuration needed - just enable the action's result with `config-template-card` and the sensor provides optimal Y-axis bounds automatically. See the **[Chart Examples Guide](chart-examples.md)** for practical examples! --- ### Chart Data Export **Entity ID:** `sensor._chart_data_export` **Default State:** Disabled (must be manually enabled) > **⚠️ Legacy Feature**: This sensor is maintained for backward compatibility. For new integrations, use the **`tibber_prices.get_chartdata`** action instead, which offers more flexibility and better performance. This diagnostic sensor provides cached chart-friendly price data that can be consumed by chart cards (ApexCharts, custom cards, etc.). **Key Features:** - **Configurable via Options Flow**: Service parameters can be configured through the integration's options menu (Step 7 of 7) - **Automatic Updates**: Data refreshes on coordinator updates (every 15 minutes) - **Attribute-Based Output**: Chart data is stored in sensor attributes for easy access - **State Indicator**: Shows `pending` (before first call), `ready` (data available), or `error` (service call failed) **Important Notes:** - ⚠️ Disabled by default - must be manually enabled in entity settings - ⚠️ Consider using the action instead for better control and flexibility - ⚠️ Configuration updates require HA restart **Attributes:** The sensor exposes chart data with metadata in attributes: - **`timestamp`**: When the data was last fetched - **`error`**: Error message if service call failed - **`data`** (or custom name): Array of price data points in configured format **Configuration:** To configure the sensor's output format: 1. Go to **Settings → Devices & Services → Tibber Prices** 2. Click **Configure** on your Tibber home 3. Navigate through the options wizard to **Step 7: Chart Data Export Settings** 4. Configure output format, filters, field names, and other options 5. Save and restart Home Assistant **Available Settings:** See the `tibber_prices.get_chartdata` action documentation for a complete list of available parameters. All action parameters can be configured through the options flow. **Example Usage:**
Show YAML: Example Usage ```yaml # ApexCharts card consuming the sensor type: custom:apexcharts-card series: - entity: sensor._chart_data_export data_generator: | return entity.attributes.data; ```
**Migration Path:** If you're currently using this sensor, consider migrating to the action:
Show YAML: Chart Data Export ```yaml # Old approach (sensor) - service: apexcharts_card.update data: entity: sensor._chart_data_export # New approach (action) - service: tibber_prices.get_chartdata data: entry_id: YOUR_CONFIG_ENTRY_ID day: ["today", "tomorrow"] output_format: array_of_objects response_variable: chart_data ```
