Smart? Right....
1. Retrieve two-pound maul from toolbox.
2. Strike fire alarm until in unidentifiable pieces on the bench.
3. Go to Home Depot and buy a $15 smoke alarm.
Sleep well. And do try not to be fooled into buying something "Smart" in the future, dummy. Replace the batteries twice a year and you probably won't be awakened at night unless something bad happens.
I wonder how many of those Nest devices are sitting in landfills now?
