The `zeroconf` component exposes your Home Assistant to the local network using [Zeroconf](https://en.wikipedia.org/wiki/Zero-configuration_networking). Zeroconf is also sometimes known as Bonjour, Rendezvous and Avahi.

```yaml
# Example configuration.yaml entry
zeroconf:
```

The registration will include metadata about the Home Assistant instance, including a base URL that can be used to access Home Assistant, the currently running Home Assistant version, and whether an API password is needed to access the instance.

```bash
$ avahi-browse -alr
+ eth0 IPv4 Home                              _home-assistant._tcp local
= eth0 IPv4 Home                              _home-assistant._tcp local
   hostname = [Home._home-assistant._tcp.local]
   address = [192.168.0.5]
   port = [8123]
   txt = ["version=0.27.0.dev0" "base_url=http://192.168.0.5:8123" "requires_api_password=true"]
```
