NetDisco

NetDisco is a Python 3 library to discover local devices and services. It allows to scan on demand or offer a service that will scan the network in the background in a set interval.

Current methods of scanning:

mDNS (includes Chromecast, Homekit)
uPnP
Plex Media Server using Good Day Mate protocol
Logitech Media Server discovery protocol
Daikin discovery protocol
Web OS discovery protocol

It is the library that powers the device discovery within Home Assistant.

We are no longer accepting PRs that implement custom discovery protocols. Only PRs that use mDNS or uPnP are supported. See this issue

Installation

Netdisco is available on PyPi. Install using pip3 install netdisco.

Example

From command-line:

python3 -m netdisco
# To see all raw data:
python3 -m netdisco dump

In your script:

from netdisco.discovery import NetworkDiscovery

netdis = NetworkDiscovery()

netdis.scan()

for dev in netdis.discover():
    print(dev, netdis.get_info(dev))

netdis.stop()

Will result in a list of discovered devices and their most important information:
