If you've been waiting to transition to smart smoke detectors, but aren't really looking forward to swapping out every. single. one. in your home, now you can just change the battery. Roost is a smart battery that gives your old detectors an upgrade.

The new version of Nest Protect announced last week is retailing for $99, but Roost batteries are $35 each or $65 for two. And while they look like a standard 9-volt, it’s actually a powerful lithium-ion that you can operate with an iOS or Android app. You can see which alarm is sounding, when it’s stopped, and even turn one off.
