The zeroconf component exposes your Home Assistant to the local network using Zeroconf. Zeroconf is also sometimes known as Bonjour, Rendezvous and Avahi.

To integrate this into Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry

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.

$ avahi-browse -alr
+ eth0 IPv4 Home                              _home-assistant._tcp local
= eth0 IPv4 Home                              _home-assistant._tcp local
   hostname = [Home._home-assistant._tcp.local]
   address = []
   port = [8123]
