Homeassistant integration for Energy Price Forecast

hacs_badge

This is an integration for the Home Assistant for the price forecast using this library.

How to use it

HACS

  1. Open your Home Assistant in a browser.
  2. In case you don't have HACS, follow the steps from here https://hacs.xyz/docs/configuration/basic.
  3. In the left menu you should have HACS icon, click it.
  4. Click on Integrations -> click 3 dots top right corner -> click Custom repositories.
  5. In the dialog window, add https://github.com/openkfw/smartenergy.awattar as a repository and select Integration as a category.
  6. Click ADD, wait for spinner to finish and close the dialog.
  7. Click EXPLORE & DOWNLOAD REPOSITORIES -> search for Awattar -> select the Awattar -> wait and click DOWNLOAD`.
  8. Go to Settings -> System -> click RESTART and wait few seconds.
  9. Go to Settings -> Devices & Services. Click the ADD INTEGRATION button.
  10. Search for Awattar -> click -> fill in details -> click SUBMIT.

Example config:

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.

  1. 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:
