The battery contains a Wi Fi radio that can communicate with your home network and a companion smartphone app. The battery also includes a microphone that listens for the smoke alarm into which it has been installed. When the alarm goes off, the battery leaps into action and handles the “smart” side of things, working much like a standalone detector. At present, there is only one smart battery on the market: the Roost Smart Battery. It’s not a perfect solution, but at just $35, it’s much more affordable than a standalone smart smoke detector. If your budget is limited, it’s definitely worth a look.
