I need this.  We have a smoke detector that is in a bad (good) place to detect smoke from the oven.  Unfortunately, this goes off all the time and you have to blow the smoke away (we usually wave a towel).  I also like the communication options.  This is one useful device and it seems very well made.

I agree naperlou - we usually grab the smoke alarm and remove it from the vicinity until the smoke dissapates when we get smoke from cooking - it would be nice not having to do that.. I wonder if it distinguisheds between a gas leak and a fire in the alarm mode? I would also like to see a battery level autodetect that would send out a signal when the batteries needed to be changed.

Nncy, good points.  With all the processing power they heve in the thing your suggestions should be easy to implement.

I agree naperlou - just add some code. Maybe have two different frequencies for the alarm or a pulse versus a tone. They might need a HW mod like an additional chip for the battery level autodetect but I think it would be well worth it. I hate not knowing how close my smoke alarms are to not being effective.

I'd like to have a nickel for all the people who've had the problem you describe, naperlou. Seems like there should be a simple solution.

perhaps some software to program against false alarms, 

if it can recognize certain times of day it gets a false alarm, and 

starts suppressing during that time, while turning up the others

or sending a text msg, saying "Alarm suppressed by logic", approve?

Ideally, this thing would have voice recognition, you could say "alarm mute" and it would silence for 20 minutes until the cooking smoke cleared. Or a smart phone app that would mute it for you at the touch of a button. A lot of people can't reach the device to silence or remove it without getting on a step stool. The arm waving thing seems silly...

There is a simple solution, one the Nest Protect uses: photoelectric not ionization smoke detection. The photoelectrics are less false alarm prone.

A major step im performance here.

This detector is certainly a major step in both performance and complexity. Most of the consumer grade detectors appear to be designed with a goal of an absolute minimum of components and general expense. This one is orders of magnitude more complex.

While I don't see much reason for including a night-light function, I really like the amr-waving motion dtector for activating the temporary switch off. As a note, an automated switch off based on anything would be extremely unsafe, since it would have no means of determining that a particular activation was not a real fire. Arm waving to fan smoke away is something that indicates a human decision has been made that the situation is not a fire in progress. So it is a very good add-on. 

That coating of the electronics is probably intended mostly to protect the package from the conductive dirt film that builds up on some ceiling mounted detectors.

As sophisticated as it is, how do you know that it doesn't alert you when the battery needs to be replaced? It would be extremely easy to do with what's already there.
