Since we were only 99.9 % sure we turned off the stove and the laptop’s camera faces the desk top, I wrote a little app that runs on a computer at home and monitors the mic signal, and sends me an email if it is too loud (which might indicate the smoke detector beeping).

At least now I know how to record audio in Swift.


(So far no smoke alarm, luckily.)

Will also take a time series of the temperature sensors in said computer.
