Nordpool

The Nordpool integration is nativly supported by this integration, so there is no need to use a template sensor. However, the following template sensor can be used to create the price input for an integration with the same output format as Nordpool.

template:
  - sensor:
      - name: "Nordpool template price sensor"
        unique_id: nordpool_template_price_sensor
        unit_of_measurement: "öre/kWh"
        state: "{{ states('sensor.nordpool_kwh_se3_sek_2_095_0') }}"
        availability: "{{ 'sensor.nordpool_kwh_se3_sek_2_095_0' | has_value }}"
        attributes:
            prices_today: >
                {%- set forecast_data = state_attr('sensor.nordpool_kwh_se3_sek_2_095_0', 'raw_today') %}
                {%- set time_key = 'start' %}
