         | shocked if this same thing could even be made at reasonable

         | 
         | The flip side to this, is Zigbee stuff always has a lot of
         | little quirks, problems, or bugs. There's literally an entire
         | module/database for ZHA (Zigbee Home Assistant addon) called
         | ZHA Quirks that's designed to work around all the little issues
         | with various devices.

         | The leaks that haunt me though... several under the house in
         | the crawl space. Copper pipe pinholes, caused I don't know how
         | much damage (including several ruined water heater elements,
         | maybe even causing the water heater to fail prematurely).
         | Ruined floors. Until they got bad enough that we had no hot
         | water (which was about the time the floor started warping),
         | there doesn't seem to be anyway that we might have noticed. The
         | water bill wasn't unusually high, or maybe it just frog-boiled
         | its way up where we couldn't. There were several more copper
         | pinholes, but they were noticed as muddy places in the
         | crawlspace while fixing the first, or just spidey-sensed. I am
         | also very nearly too fat to crawl under the house, let alone do
         | emergency plumbing while there.
         | 
         | Another incident involved a squirrel. The idiot owners of this
         | house (before us, not the current idiot owners) decided that
         | the easiest place to put new plumbing was in the ceiling (maybe
         | they were too fat too?). Our attic had a new uninvited guest,
         | and apparently PEX piping is very tasty. Or appears that way,
         | the squirrel lost his appetite after biting enough of a hole
         | that there was a leak from above. This leak though, despite the
         | location which should have made it almost instantly obvious,
         | happens almost within 5 minutes of a torrential downpour that
         | lasted better than an hour. That, plus my unwillingness to
         | believe the previous owners had routed plumbing above
         | everyone's heads, meant we didn't get that taken care of quite
         | as quickly as we might have.
         | 
         | My lessons from this, I think, are:
         | 
         | 1. We might have caught the crawlspace leaks quickly if there
         | were a humidity sensor (is that how the leak sensors work?)
         | down there, and we could have compared to baseline. That is, if
         | spraying water didn't just fry them immediately.
         | 
         | 2. The ceiling leak probably couldn't have been detected very
         | early, given the coincidence with the rain and how it would
         | have raised humidity. Possibly if we had a water pressure
         | sensor, that would have picked it up as a drop, despite there
         | being no faucets running.
         | 
         | Plumbing sucks. Houses build 50 years ago assumed that it could
         | never fail often enough to make it easily accessible. My next
         | house will take into consideration squirrel mitigation
         | concerns.
