NEW YORK: There’s nothing worse than waking up in the middle of the night to the chirping sound of your smoke detector, wailing practically for the whole town to hear that it’s low on battery.
While smart smoke detectors from companies like Nest warn you ahead of time when the battery is low, it cost $99.
But a new company called Roost is offering a smart battery for your existing smoke detector that essentially lets you retrofit your way into a connected home.
