&gt; I&#x27;ve never understood the desire to add smart technology to the smoke alarm.<p>Because very few things suck more than coming home from work and your house is burnt down because the smoke alarm wasn&#x27;t heard by anyone and by the time the fire crews arrive it&#x27;s too late. Happened to a friend of mine, house was beyond repair even though fire crews arrived 10min after a passing driver noticed the blaze.
