python-zeroconf

Documentation.

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)

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:

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()

If you don’t know the name of the service you need to browse for, try:

from zeroconf import ZeroconfServiceTypes
print('\n'.join(ZeroconfServiceTypes.find()))
