First, I'll preface this that I'm an engineer for a smoke alarm company, so I may be a bit biased. The simple answer is that the rules forbid a smoke alarm feature like you (and many others) would like. Fortunately, if you switch to a photoelectric alarm in a proper location, you should not get false alarms from cooking. Now here's the long answer: Essentially all smoke alarms in the United States are tested and listed to UL217, which has specific requirements and restrictions for smoke alarms. UL217, Section 7 discusses alarm silencing means. Among many other things, it says "It is not prohibited that each single and multiple station smoke alarm be provided with an automatically resettable alarm silencing means that has a fixed or variable time setting which desensitizes the alarm for a maximum of 15 minutes. Alarm silencing shall not disable the smoke alarm. Sensitivity shall not be reduced to more than 4 percent per foot of obscuration." So we're only allowed to slightly desensitize the alarm for up to 15 minutes; never disable it. Fortunately, the whole problem is moot if you switch to a photoelectric alarm (around $25) instead of an ionization alarm (<$10). Ionization alarms will false alarm from cooking byproducts far too quickly; photoelectric alarm generally do not. You also should not place a smoke alarm in the kitchen (this is a perfect location for heat alarms). While ionization alarms will go off far too quickly from cooking, they also fail to response to slow smoldering fires. There are many videos of rooms and test boxes filled with smoke that fail to trigger an ionization alarm, while the photoelectric alarm is working fine. Some states have even outlawed ionization alarms. Buy a decent photoelectric alarm with a 10-year battery, like the ones made by First Alert or Kidde, and you probably won't have to worry about your smoke alarms for 10 years. That's even better than Nest that needs to be thrown away after 7 years. I don't work for any of the companies mentioned above either...
