They walk in the front door. AIRHORN.

Open this page in Safari on an iPhone. The file goes straight into Shortcuts.
What happens
When their phone joins the home Wi-Fi, the volume goes to max and an airhorn blasts. At most once an hour, so a flaky router can’t make it a siren.
Setup
- Open the download on their phone (or AirDrop it over) and tap Add Shortcut.
- Long-press it in Shortcuts → All Shortcuts → Rename and call it Wi-Fi Helper, so it doesn’t give itself away.
- Shortcuts → Automation → + → Wi-Fi, pick their home network, select Run Immediately, tap Next and choose the shortcut.
- Run it once now and tap Always Allow on every prompt, or the prank fizzles on a permission dialog later.
Undo
Open Shortcuts → Automation, swipe left on the automation and tap Delete. Then delete the shortcut.
