Ah-ha Now I understand.
Monitoring sound.
How about this?
If you have a Google Nest device,
it may be possible to monitor the sound outside. Then it may be able to trigger something.

Wow, that's new to meAha! On my device "Samsung Galaxy",
I found a Sound Detector ability.
It can catch a sound of Baby crying or Alarm siren etc.
I didn't know that until now.
Don't you have the similar one on your device?
