Know_devides

Hi guys i’ve some problem with the know_devices.yaml.
How can i reduce the device tracked? Because my know device.yaml is long 35000 lines and i’ve some error reported in the log.
I use only the bluetooth tracker with this configuration:
device_tracker:

  • platform: bluetooth_tracker

    consider_home: 10
    new_device_defaults:
    track_new_devices: true

I see also wi-fi device.
