luis_in_brief, (edited ) So! Are there any smart fire alarms that aren’t awful? Just had a false negative from my Nest.
A few months after we moved in we had a lint fire, so I put a Nest in the laundry room.
3ish years later, just had another lint fire, with enough smoke that my upstairs neighbor (shares an airwell) ran downstairs frantically; we didn’t smell it because the door was closed, concentrating the smell in the small laundry room with the silent Nest.
Just ran a Nest test and it says it is fine.
