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

## {% linkable_title 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
```

### {% linkable_title Note %}

This replaces the previous `api_streams` sensor.
