The statement "A smoke alarm in or near the kitchen is incorrectly placed if it is producing frequent false alarms" may very well be true but it doesn't matter. People have and will continue to disable their smoke/CO detectors if they are annoying. The ability to simply wave at the detector to get it to shut off (Like after burning your toast) means that people will simply wave to shut off the alarm instead of disabling it.
Even with what I know about fire death statistics, best practices, and what not I have disabled fire detectors before for any/all of the following reasons:
* Low battery alarm
* Going off at just a whiff of smoke
* Randomly making noises even after replacing the battery
Now you can say that it was incredibly stupid of me to disable them, and it probably was, but that doesn't change the fact that people's first instinct is just to disable it.
So yes, I think the Nest smoke alarm does have a major upside: people in my situation would actually use it.
Like the nest?
I would. You would. But we're not the norm. Not all products are designed toward the DIY crowd.
