The `fixer` sensor will show you the current exchange rate from [Fixer.io](https://fixer.io/) which is using data from the [European Central Bank (ECB)](https://www.ecb.europa.eu).

To get an overview about the available [currencies](https://fixer.io/symbols).

## Setup

You need to create an [API key](https://fixer.io/product). There is a rate limit of 1000 calls per month.

## Configuration

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

```yaml
# Example configuration.yaml entry
