# Example: phone notification when a family member is recognized.
#
# One faceid/event message is published per (Frigate event, person), so this
# will not spam you with repeats of the same sighting. mode: queued makes sure
# two people recognized at the same time both produce a notification; the
# per-person notification tag replaces a still-visible message instead of
# stacking. faceid/event is published without the MQTT retain flag, so a
# Home Assistant restart cannot re-fire these triggers on a stale message.
