The `websocket_api` sensor platform shows how many clients are connected to the stream API.

## Configuration

To add the connected clients to your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: websocket_api
```

### Note

This replaces the previous `api_streams` sensor.
The default sensor name is `connected_clients`.
