My ideal version of this kind of monitoring is an interface that lets me teach an app what doing things in the house sounds like - new activity name: shut door and lock > record a few runthroughs; then log when it happens, offer push notifications, etc. I have an induction range that helpfully makes lots of beeping noises while many gas ones do not (but also turns itself off), so that would also be possible.
