I personally don't believe in having an "smart" devices in my home, but a friend of mine has a "smart" smoke alarm that sends an alert to his phone if the fire alarm is triggered and the alert includes an option to contact the fire department. Automatically contacting the fire department is not necessarily a good idea, especially since the vast majority of alerts he gets from his smart fire alarm are due to too routine emissions from his coffee maker.
