Zeroconf/Avahi/Bonjour
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
zeroconf:
The registration will include meta-data 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. The examples below show two ways to retrieve the details for testing.
$ avahi-browse -alr
