Learned my lesson after a trip last week… I have sensors for nearly everything, but somehow totally forgot about the Fridge / Freezer.
A power outage made my fridge lose it’s mind and turn off cooling, even after it powered back up. Unplug / replug seems to have fixed it, but all the food was spoiled when we got home. Simple $10 temperature sensor could have saved everything!
Water sensor near your washing machine.
And a smart speaker connected to HA in the bedroom to play a alarm once the smoke detector goes off.
I’ve yet to experience a smoke detector quiet enough that I couldn’t hear it throughout my entire house
Yeah, that seems like over kill. Especially if you’re not hard of hearing.
Only thing I’d worry about is maybe one in the basement, behind closed door, and being asleep in 2nd flood bedroom?
Guess it would just depend how light of sleeper you are though.
I definitely have the water sensors covered, even have a water shut-off valve tied to them (that’s the one I’m most paranoid about).
Interesting idea w/ the smoke alarm ‘relay’. I have some echo dots, that in theory are supposed to pick up smoke alarm sounds when in ‘guard’ mode. The water sensors I have throughout the house also have temperature sensors (and I have others from ecobee), I have those send an alert if they ever get way too hot or too cold, and announce that over speakers. In theory that could also help with detection of fires or failed HVAC, etc…
