NetDisco

NetDisco is a Python library to discover local devices and services. It uses mDNS and uPnP to scan the network and supports Python 2 and 3. It allows to scan on demand or offer a service that will scan the network in the background in a set interval.

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

Installation

Netdisco is available on PyPi. Install using pip3 install netdisco (use pip if you're still on Python 2).

Example

From command-line:

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

In your script:

import time
import netdisco

netdis = netdisco.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:
