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/k3dt/ote_rate as custom repository.

Once you've installed the custom integration, add the following to your configuration.yaml file:

sensor:
  platform: ote_rate

If you have an exchange rate sensor - you can calculate the value in local currency using template sensor:

  platform: template
    sensors:
      czk_price_per_kwh:
        friendly_name: "Current Electricity Price"
        value_template: >-
          {% set CURRENT_PRICE = states("sensor.current_ote_energy_cost") | float(0) %}
          {% set EUR_CZK = states("sensor.exchange_rate") | float(0) %}
          {{- (CURRENT_PRICE * EUR_CZK / 1000) | round(3) -}}
        unit_of_measurement: "CZK/kWh"
