This is an integration providing current price per megawatt of energy based on the quote from ote-cr.cz
Copy this folder to <config_dir>/custom_components/ote_rate/.
If you're using HACS - feel free to add https://github.com/grinco/ote_rate as custom repository.
Once you've installed the custom integration, add this integration through the integration setup UI.
You can calculate price in a local currency, either using custom value or exchange rate sensor (follow setup flow).
For example if you sell energy and your provider has some fee, you can set costs which will be deducted from OTE price.
