TBD

Make sure that there is no trailing slash in the API host, otherwise the validation fails. When pressing submit, validation will also check the connectivity and fails if not able to connect and authenticate.

11. Go to the dashboard screen, you should see bunch of sensors for the Awattar integration.

Example Lovelace card

Since the forecast is an array of values, it's not possible to nicely display by default as a card. However, you can install this integration https://github.com/RomRider/apexcharts-card. In the card configuration provide:

type: custom:apexcharts-card
graph_span: 1d
span:
  start: hour
header:
  show: true
  title: Awattar Price Forecast
  show_states: true
  colorize_states: true
now:
  show: true
  label: Now
series:
  - entity: sensor.smartenergy_awattar_forecast
    data_generator: |
      return entity.attributes.forecast.map((f, index) => {
        return [f.start_time, f.marketprice];
      });

Outcome should look like this:
