I did a python update to 3.10.1 and got a new version of homeassistant on top. Im now running core-2021.12.9. After the update the nmap tracker added new device_tracker entities and seems to ignore the known_devices file on which a lot of my automations rely. Any idea how to migrate/fix this?
You shouldn’t be directly using known_devices.yaml. That is a file used internally by HA, and was deprecated back in 2019.
Thats what I found online after my research too, but I couldn’t find what to use instead. Today I looked at my integrations page coincidentally and saw a new Nnap Tracker Integration. For anybody facing the same issue, delete the old nmap tracked devices in known_devices, restart homeassistant and rename the automatically added nmap entities to your preference.
