Integration to integrate with IEC API.

This integration will set up the following platforms.

Automatic (HACS):

1. Add this path to HACS: https://github.com/GuyKh/iec-custom-component
2. Install through HACS

Manual:

1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
2. If you do not have a custom_components directory (folder) there, you need to create it.
3. In the custom_components directory (folder) create a new folder called iec.
4. Download all the files from the custom_components/iec/ directory (folder) in this repository.
5. Place the files you downloaded in the new directory (folder) you created.
6. Restart Home Assistant
7. In the HA UI go to "Configuration" -> "Integrations" click "+" and search for "IEC"

To view logs in debug add this to configuration.yaml:

logger:
  default: info
  logs:
    ...
    custom_components.iec: debug
    iec_api: debug

The component currently fetches data from IEC every hour, but IEC doesn't update the data very often and they don't really have a consistant behavior, it could arrive with 2 days delay.

Yes.
However, the only difference is that in the Invoices you'll see balance = 0 since you're paying to the private company

No.
You should do it only once when configuring the component.

Yes, But....
You would only get a subset of sensors, based on your Invoice information.

You can head to usage and examples page to see examples of this components used in cards in HomeAssistant
