## Automation Examples> **Note:** See the [full automation examples guide](https://jpawlowski.github.io/hass.tibber_prices/user/automation-examples) for more advanced recipes.

### Run Appliances During Cheap Hours

Use the `binary_sensor.tibber_best_price_period` to automatically start appliances during detected best price periods:

```yaml
automation:
    - alias: "Run Dishwasher During Cheap Hours"
      trigger:
          - platform: state
            entity_id: binary_sensor.tibber_best_price_period
            to: "on"
      condition:
          - condition: time
            after: "21:00:00"
            before: "06:00:00"
      action:
          - service: switch.turn_on
            target:
                entity_id: switch.dishwasher
```

> **Learn more:** The [period calculation guide](https://jpawlowski.github.io/hass.tibber_prices/user/period-calculation) explains how Best/Peak Price periods are identified and how you can configure filters (flexibility, minimum distance from average, price level filters with gap tolerance).

### Notify on Extremely High Prices

Get notified when prices reach the VERY_EXPENSIVE level:

```yaml
automation:
    - alias: "Notify on Very Expensive Electricity"
      trigger:
          - platform: state
            entity_id: sensor.tibber_current_interval_price_level
            to: "VERY_EXPENSIVE"
      action:
          - service: notify.mobile_app
            data:
                title: "⚠️ High Electricity Prices"
                message: "Current electricity price is in the VERY EXPENSIVE range. Consider reducing consumption."
```

### Temperature Control Based on Price Ratings

Adjust heating/cooling when current prices are significantly above the 24h average:

```yaml
automation:
    - alias: "Reduce Heating During High Price Ratings"
      trigger:
          - platform: numeric_state
            entity_id: sensor.tibber_current_interval_price_rating
            above: 20 # More than 20% above 24h average
      action:
          - service: climate.set_temperature
            target:
                entity_id: climate.living_room
            data:
                temperature: 19 # Lower target temperature
```

### Smart EV Charging Based on Tomorrow's Prices

Start charging when tomorrow's prices drop below today's average:

```yaml
automation:
    - alias: "Smart EV Charging"
      trigger:
          - platform: state
            entity_id: binary_sensor.tibber_best_price_interval
            to: "on"
      condition:
          - condition: numeric_state
            entity_id: sensor.tibber_current_interval_price_rating
            below: -15 # At least 15% below average
          - condition: numeric_state
            entity_id: sensor.ev_battery_level
            below: 80
      action:
          - service: switch.turn_on
            target:
                entity_id: switch.ev_charger
```

## Troubleshooting

### No data appearing

1. Check your API token is valid at [developer.tibber.com](https://developer.tibber.com/settings/access-token)
2. Verify you have an active Tibber subscription
3. Check the Home Assistant logs for detailed error messages (`Settings > System > Logs`)
4. Restart the integration: `Settings > Devices & Services > Tibber Price Information & Ratings > ⋮ > Reload`

### Missing tomorrow's price data

-   Tomorrow's price data typically becomes available between **13:00 and 15:00** each day (Nordic time)
-   The integration automatically checks more frequently during this window
-   Check `binary_sensor.tibber_tomorrows_data_available` to see if data is available
-   If data is unavailable after 15:00, verify it's available in the Tibber app first

### Prices not updating at quarter-hour boundaries

-   Entities automatically refresh at 00/15/30/45-minute marks without waiting for API polls
-   Check `sensor.tibber_data_expiration` to verify data freshness
-   The integration caches data intelligently and survives Home Assistant restarts

### Currency or units showing incorrectly

-   Currency is automatically detected from your Tibber account
-   Display mode (base currency vs. subunit) can be configured in integration options: `Settings > Devices & Services > Tibber Price Information & Ratings > Configure`
-   Supported currencies: EUR, NOK, SEK, DKK, USD, and GBP
-   Smart defaults apply: EUR users get subunit (ct), Scandinavian users get base currency (kr)

## Advanced Features

### Sensor Attributes

Every sensor includes rich attributes beyond just the state value. These attributes provide context, timestamps, and additional data useful for automations and templates.

**Standard attributes available on most sensors:**

-   `timestamp` - ISO 8601 timestamp for the data point
-   `description` - Brief explanation of what the sensor represents
-   `level_id` and `level_value` - For price level sensors (e.g., `VERY_CHEAP` = -2)

**Extended descriptions** (enable in integration options):

-   `long_description` - Detailed explanation of the sensor's purpose
-   `usage_tips` - Practical suggestions for using the sensor in automations

**Example - Current Price sensor attributes:**

```yaml
timestamp: "2025-11-03T14:15:00+01:00"
description: "The current electricity price per kWh"
long_description: "Shows the current price per kWh from your Tibber subscription"
usage_tips: "Use this to track prices or to create automations that run when electricity is cheap"
```

**Example template using attributes:**

```yaml
template:
    - sensor:
          - name: "Price Status"
            state: >
                {% set price = states('sensor.tibber_current_electricity_price') | float %}
                {% set timestamp = state_attr('sensor.tibber_current_electricity_price', 'timestamp') %}
                Price at {{ timestamp }}: {{ price }} ct/kWh
```
