Last year, Roost made an interesting proposition. Keep your traditional smoke detectors but make them smarter simply by using its 9V Smart Battery. That was practically all you needed to do to get things like alarm notifications, battery level alerts, and even naming your smoke detectors. Today, however, Roost is finally jumping in all the way in the smart appliance market. It is announcing the Roost Smart Smoke Alarm that gives all that and more in one single package. And yes, it still includes the smart battery.
