Notes

  • TVs, phones, and other household devices should not be promoted to canonical inventory unless they become infrastructure-relevant.
  • Addresses on dynamic household devices may change and should be treated as observations only.
  • Unknown Ubuntu hosts are good candidates for SSH-based identification before being added to hosts.yml.
  • 192.168.1.102 was promoted to canonical inventory as klipper-3d-printer.
