:alt: Documentation Status
`Documentation <https://python-zeroconf.readthedocs.io/en/latest/>`_.
This is fork of pyzeroconf, Multicast DNS Service Discovery for Python,
originally by Paul Scott-Murphy (https://github.com/paulsm/pyzeroconf),
modified by William McBrine (https://github.com/wmcbrine/pyzeroconf).
The original William McBrine's fork note::
This fork is used in all of my TiVo-related projects: HME for Python
(and therefore HME/VLC), Network Remote, Remote Proxy, and pyTivo.
Before this, I was tracking the changes for zeroconf.py in three
separate repos. I figured I should have an authoritative source.
Although I make changes based on my experience with TiVos, I expect that
they're generally applicable. This version also includes patches found
on the now-defunct (?) Launchpad repo of pyzeroconf, and elsewhere
around the net -- not always well-documented, sorry.
Compatible with:
* Bonjour
* Avahi
Compared to some other Zeroconf/Bonjour/Avahi Python packages, python-zeroconf:
* isn't tied to Bonjour or Avahi
* doesn't use D-Bus
* doesn't force you to use particular event loop or Twisted (asyncio is used under the hood but not required)
* is pip-installable
* has PyPI distribution
* has an optional cython extension for performance (pure python is supported as well)
Python compatibility
--------------------
* CPython 3.9+
* PyPy 3.9+
Versioning
----------
This project uses semantic versioning.
Status
------
This project is actively maintained.
Traffic Reduction
-----------------
Before version 0.32, most traffic reduction techniques described in https://datatracker.ietf.org/doc/html/rfc6762#section-7
where not implemented which could lead to excessive network traffic. It is highly recommended that version 0.32 or later
is used if this is a concern.
IPv6 support
------------
IPv6 support is relatively new and currently limited, specifically:
* `InterfaceChoice.All` is an alias for `InterfaceChoice.Default` on non-POSIX
systems.
* Dual-stack IPv6 sockets are used, which may not be supported everywhere (some
BSD variants do not have them).
* Listening on localhost (`::1`) does not work. Help with understanding why is
appreciated.
How to get python-zeroconf?
===========================
* PyPI page https://pypi.org/project/zeroconf/
* GitHub project https://github.com/python-zeroconf/python-zeroconf
The easiest way to install python-zeroconf is using pip::
pip install zeroconf
How do I use it?
================
Here's an example of browsing for a service:
.. code-block:: python
from zeroconf import ServiceBrowser, ServiceListener, Zeroconf
class MyListener(ServiceListener):
def update_service(self, zc: Zeroconf, type_: str, name: str) -> None:
print(f"Service {name} updated")
def remove_service(self, zc: Zeroconf, type_: str, name: str) -> None:
print(f"Service {name} removed")
def add_service(self, zc: Zeroconf, type_: str, name: str) -> None:
info = zc.get_service_info(type_, name)
print(f"Service {name} added, service info: {info}")
zeroconf = Zeroconf()
listener = MyListener()
browser = ServiceBrowser(zeroconf, "_http._tcp.local.", listener)
try:
input("Press enter to exit...\n\n")
finally:
zeroconf.close()
.. note::
Discovery and service registration use *all* available network interfaces by default.
If you want to customize that you need to specify ``interfaces`` argument when
constructing ``Zeroconf`` object (see the code for details).
If you don't know the name of the service you need to browse for, try:
.. code-block:: python
from zeroconf import ZeroconfServiceTypes
print('\n'.join(ZeroconfServiceTypes.find()))
See examples directory for more.
