# ENTSO-E Binding

This binding fetches day-ahead energy spot prices from ENTSO-E, the European Network of Transmission System Operators for Electricity.

Users can select a specific area to retrieve the relevant energy prices. This binding helps users monitor and manage their energy consumption based on real-time pricing data. It is recommended to use this binding together with a currency provider (e.g. Freecurrency binding (opens new window)) for exchanging euro spot prices to local currency.

# Supported Things

  • day-ahead: This is the main and single Thing of the binding.

# Thing Configuration

# Value-Added Tax

VAT is not included in any of the prices. To include VAT for items linked to the Number:EnergyPrice channel, the VAT profile (opens new window) can be used. This must be installed separately. Once installed, simply select "Value-Added Tax" as Profile when linking an item.

# Total Price

Please note: There is no channel providing the total price. Instead, create a group item with SUM as aggregate function and add the individual price items as children. Read more about how to in this similar binding Energi Data Service (opens new window)

# Trigger Channels
