The `geizhals` sensor will give you the best price of a product from [Geizhals](https://geizhals.de) or related site. With this information can be used in e.g., automations to notify you when a price drops.

To enable this sensor, add the following lines to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: geizhals
    name: qc35
    product_id: 1453021
```

Configuration variables:

- **name** (*Required*): The internal name of the product in Home Assistant.
- **product_id** (*Required*): ID of the product. Get the ID from the geizhals website of your chosen product by clicking on the *Price History* tab, e.g., [here](https://geizhals.de/?phist=1453021). The URL of this site reveals the ID, e.g., <https://geizhals.de/?phist=1453021> with `product_id: 1453021`.
- **description** (*Optional*): The name of the product in the front end.
- **domain** (*Optional*): Domain which should be used for the request. Set this to `geizhals.at`, `geizhals.eu`, `geizhals.de`, `skinflint.co.uk` or `cenowarka.pl`. Defaults to `geizhals.de`.
- **regex** (*Optional*): Regular expression to parse the price. Default: `\D\s(\d*)[\,|\.](\d*)`.
