Energy & Tax Attributes

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.

Most price sensors include energy price and tax attributes that break down the total price into its components:

Show formula

total = energy_price + tax

These attributes appear on all price sensors that display a raw price (not on percentage, level, or trend sensors). The energy_price is the raw spot/market price, while tax includes all fees, surcharges, and taxes added by your electricity provider.

Transition After Update

After updating the integration, the energy_price and tax attributes will appear gradually as new price data is fetched from the Tibber API. Existing cached intervals (up to ~2 days old) won't have these fields yet — the attributes will simply be absent until fresh data replaces them. No action needed.

Where These Attributes Appear

Sensor Type	energy_price	tax	Notes
Current/Next/Previous Interval Price	✅	✅	Single interval values
Rolling Hour Average	✅	✅	Averaged across 5 intervals
Daily Min/Max/Average	✅	✅	Aggregated for the day
Trailing/Leading 24h	✅	✅	Aggregated across window
Future Average (N-hour)	✅	✅	Averaged across future window
Levels, Ratings, Trends	❌	❌	Not price sensors
Volatility	❌	❌	Statistical, not price

Use Cases

Solar Feed-In & Net Metering (Saldering)

In countries like the Netherlands, solar feed-in compensation is based on the raw energy/spot price, not the total consumer price. The energy_price attribute gives you exactly this value — no more reverse-engineering from the total price with fragile template calculations.

Show YAML: Solar Feed-In and Net Metering

# Example: Decide whether to export solar power or consume it
# Compare energy price (what you'd earn by exporting) vs. total price (what you'd pay)
automation:
    - alias: "Solar: Export or Consume"
      trigger:
          - platform: numeric_state

                {% set total = states('sensor.<home_name>_current_electricity_price') | float %}
                {# Export when energy price is high relative to total — you earn more #}
                {{ energy is not none and energy > (total * 0.4) }}
      action:
          - service: switch.turn_off
            entity_id: switch.battery_charging  # Don't charge battery, export instead

Price Composition Analysis

Understand how your electricity price is structured — useful for comparing across days or spotting trends in market prices vs. fees:

Show YAML: Price Composition Analysis

# Template sensor showing tax share
template:
    - sensor:
          - name: "Electricity Tax Share"
            unit_of_measurement: "%"
            state: >
                {% set tax = state_attr('sensor.<home_name>_current_electricity_price', 'tax') %}
                {% set total = states('sensor.<home_name>_current_electricity_price') | float %}
                {% if tax is not none and total > 0 %}
                  {{ ((tax / total) * 100) | round(1) }}
                {% else %}
                  unavailable
                {% endif %}

Country-Specific Calculations

The composition of the tax field varies by country (Norway, Sweden, Germany, Netherlands each have different fee structures). For detailed examples of how to build country-specific calculations using input_number helpers and template sensors — including Dutch solar feed-in compensation (saldering) — see the Community Examples page.

In Chart Data Actions

The energy_price and tax fields are also available in the get_chartdata action. See Chart Actions — Energy & Tax Fields for details.
