&lt;strong&gt;Nest Protect smoke alarm.&lt;/strong&gt; From the company that brought you the smart thermostat comes a rethinking of another home necessity: a smoke alarm and carbon monoxide detector. Instead of shrieking beeps, the Nest Protect offers remote access, chimes and an urgent voice. It's a touch of &quot;civility,&quot; The New York Times said. Also, it knows the difference between a raging fire and burnt toast. ($129)
