Custom component for Home Assistant to fetch energy prices of all European countries from the ENTSO-e Transparency Platform (https://transparency.entsoe.eu/). Day ahead energy prices are added as a sensor and can be used in automations to switch equipment. A 24 Hour forecast of the energy prices is in the sensors attributes.

You need an ENTSO-e Restful API key for this integration. To request this API key, register on the Transparency Platform and send an email to [email protected] with “Restful API access” in the subject line.

The integration adds the following sensors:

• Average Day-Ahead Electricity Price Today
• Highest Day-Ahead Electricity Price Today
• Lowest Day-Ahead Electricity Price Today
• Current Day-Ahead Electricity Price
• Current Percentage Relative To Highest Electricity Price Of The Day
• Next Hour Day-Ahead Electricity Price
• Time Of Highest Energy Price Today
• Time Of Lowest Energy Price Today

Download this repository and place the contents of custom_components in your own custom_components map of your Home Assistant installation. Restart Home Assistant and add the integration through your settings.

Add https://github.com/JaccoR/hass-entso-e to your HACS custom repositories and install through HACS. Restart Home Assistant and add the integration through your settings.

The sensors can be added using the web UI. In the web UI you can add your API-key and country and the sensors will automatically be added to your system. There is an optional field for an additional cost template.

In the optional field Additional Cost Template a template for additional costs, like hourly fixed costs, can be added. When left empty, no additional costs are added. In this template now() always refers start of the hour of that price. this way we can calculate the correct costs and add that to the day ahead prices.

An example template is given below:

{% set s = {
    "hourly_fixed_cost": 0.5352,
    "winter_night": 0.265,
    "winter_day": 0.465,
    "summer_day": 0.284,
    "summer_night": 0.246,
    "cert": 0.01
}
%}
{% if now().month >= 5 and now().month <11 %}
    {% if now().hour >=6 and now().hour <23 %}
        {{s.summer_day+s.hourly_fixed_cost+s.cert|float}}
    {% else %}
        {{s.summer_night+s.hourly_fixed_cost+s.cert|float}}
    {% endif %}
{% else %}
    {% if now().hour >=6 and now().hour <23 %}
        {{s.winter_day+s.hourly_fixed_cost+s.cert|float}}
    {%else%}
        {{s.winter_night+s.hourly_fixed_cost+s.cert|float}}
    {% endif %}
{% endif %}

The integration is in an early state and receives a lot of updates. If you already setup this integration and encounter an error after updating, please try redoing the above installation steps.
