A smart home needs to be a connected home, but the fact that a home is connected doesn’t necessarily make it smart. When it comes to safety, though, there really is a new level of intelligent connectedness available in today’s generation of smart smoke alarms.
At their most basic, and cheapest, they can alert you remotely via a mobile app when an alarm is activated. In fact, a device like the Roost Smart Battery can smarten up any standard, functioning smoke detector – as long as it’s battery-powered or has a battery backup – for about $60. This deceptively simple device is a lithium nine-volt battery with a Wi-Fi chip and a microphone that “hears” your alarm.
Not only will you get an alert when the alarm is activated, you’ll also get one when the battery needs replacing. No more annoying low-battery chirps, and yes, you can just swap in any standard 9-volt cell when it’s time.
