MMM-FiElectricityPrice

Magic Mirror Module to display Finnish electricity prices from Nord Pool. The module can be used to show data from other regions from Nord Pool, but I have not tested it with them.

The module loads the electricity prices when started and then every day at 16:01 local time of your MagicMirror installation. The prices are shown as a bar chart with optional average value and highlights for high and low prices, both limits are configurable.

The module reads the data that is shown on this page: https://www.nordpoolgroup.com/en/Market-data1/Dayahead/Area-Prices/FI/Hourly/?view=table
