Here’s my real scenario: weekend place somewhere farther our, solid internet connection, have a SmartThings hub that I use to control heat and other stuff. There is one neighbor relatively close, meaning also far out, and that neighbor told me the other day that at 3:00 AM somebody pulled up in a car and laid on the horn for half a minute, then waited. When she turned on her light, the car took off.
Hmmmm. Somebody was checking to see whether anybody was home, and the way they did that was by making noise and checking whether something happened. If you walk up to a place and the lights go on, well, that’s a motion detector, doesn’t tell you anything if somebody’s in or not. But if you make noise in the middle of the night and there’s no reaction, quite likely there’s nobody there.
So what I’d like to do is put a noise detector there, and if there’s a burst of noise (and nobody’s home), wait a couple of seconds, then turn on bedroom lights, then turn on outside lights. Problem is that I don’t see a noise sensor that would figure out whether there’s noise (yes, a microphone will give me plenty of information, but not condensed down to what I’d like, some sort or signal I could use to trigger the sequence of lightups (possibly including cameras, come to think of it). I see the “Quirky Spotter Uniq” which appears to be in limbo and… nothing else. Is there a device out there that would detect something like a honking horn ? Thanks for any pointers.
