## Custom Font _(Manual Step Required)_

To achieve the digital clock-style font for the prices as seen in the screenshots, you need to add the stylesheet to your Lovelace resources.

1.  Copy the [`stylesheet.css`](https://raw.githubusercontent.com/timmaurice/lovelace-tankerkoenig-card/refs/heads/main/dist/stylesheet.css) file from the `dist` folder of this repository into your `config/www/community/lovelace-tankerkoenig-card/` directory.
2.  Add the stylesheet as a resource in Home Assistant under `Settings` -> `Dashboards` -> `⋮` (top right) -> `Resources`.
    - URL: `/hacsfiles/lovelace-tankerkoenig-card/stylesheet.css`
    - Resource Type: `Stylesheet (CSS)`

## Development

<details>
<summary>To contribute to the development, you'll need to set up a build environment.</summary>

1.  **Clone the repository:**

```bash
    git clone https://github.com/timmaurice/lovelace-tankerkoenig-card.git
    cd lovelace-tankerkoenig-card
    ```

2.  **Install dependencies:**

```bash
    npm install
    ```

3.  **Start the development server:**
    This command will build for changes in the `src` directory and rebuild the card.

```bash
    npm run build
    ```

4.  In your Home Assistant instance, you will need to configure Lovelace to use the local development version of the card from `dist/tankerkoenig-card.js`.

### Local Testing with Docker

To test your compiled card locally without modifying your production Home Assistant setup:

1. Build the card with `npm run build` or keep it auto-compiling using `npm run watch`.
2. Run `npm run docker:start` to spin up a local Home Assistant container.
3. Access Home Assistant at [http://localhost:8123](http://localhost:8123) and complete the onboarding process.
4. Navigate to **Settings** -> **Dashboards** -> **⋮** (top right) -> **Resources**.
5. Add the url `/local/tankerkoenig-card/tankerkoenig-card.js` with the Resource Type `JavaScript Module`.
6. Add the official Tankerkönig integration in Home Assistant so you have dummy sensors to test with.
7. Add the custom card in your local dashboard to verify your changes!

When you're done, you can clean up the environment by running `npm run docker:stop`. Note that your configuration will persist in the `test/ha-config` folder.
