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!
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.
Most newer ones are interconnected too so all of them in the house go off if one goes off. I’m not sure if that’s a code requirement but it might be in some places.
