Discovery

This is the legacy discovery integration for Home Assistant. It’s use is no longer recommended. Use the SSDP, Zeroconf and USB integrations instead.

This integration is limited to detect:

To load this integration, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
discovery:
  ignore:
    - yamaha
    - logitech_mediaserver

Troubleshooting

mDNS and UPnP

Home Assistant should be on the same network as the devices for mDNS and UPnP discovery to work.

When running Home Assistant Core in a Docker container command line option --net=host or the compose file equivalent network_mode: host must be used to put it on the host’s network, otherwise mDNS and UPnP will not work.

If mDNS is still not working:

  • Make sure there are no firewall rules blocking mDNS traffic. mDNS relies on sending and receiving UDP multicast packets on port 5353.
  • mDNS traffic may not be forwarded correctly between the wired and wireless interfaces of a Wi-Fi AP or router.

mDNS forwarding

If it’s not possible to have Home Assistant and the devices on the same network, mDNS forwarding may allow mDNS discovery between networks.

mDNS forwarding is a configurable option in some routers. It can also be called mDNS reflector or mDNS repeater, depending on the manufacturer.

Windows

64-bit Python

There is currently a known issue with running this integration on a 64-bit version of Python and Windows.

Could not install dependency netdisco

If you see Not initializing discovery because could not install dependency netdisco==0.6.1 in the logs, you will need to install the python3-dev or python3-devel package on your system manually (eg. sudo apt-get install python3-dev or sudo dnf -y install python3-devel). On the next restart of Home Assistant, the discovery should work. If you still get an error, check if you have a compiler (gcc) available on your system.
