You won't regret coming home to RoostA 9V battery with brains, Roost adds smarts to your smoke detectors
[MUSIC] I'm here at the c/net smart home with the Roost Smart Battery. Now this might look like a regular old nine volt but I did not go trolling the aisles of. CVS looking for something to talk about. This thing actually takes the traditional nine volt form and, oh my god, it's [UNKNOWN]. It's actually kind of a really cool clever solution of retrofitting old Smoke detectors with wi-fi compatibility. Complete with its own iOS and Android app, [UNKNOWN] a clever alternative to something like a [UNKNOWN]. You place it into your smoke or carbon monoxide detector, then no matter where you are, if that detector's alarm sounds. [SOUND] You're going to get notified. Since this guy is only $35, if you have a big home with lots of smoke detectors, it'd be a lot easier to make all of the smarts with this guy than the $100 nest and I'm happy to say it works pretty well. It's simple. It's small. It only promises to do one thing. But it takes that one thing and really adds a lot of polish to it. The app is really well designed. It guides you through setup carefully. It's also easy to add multiple users to your app. So your significant other, your kids, all of them can monitor your Your smoke detectors with their smartphones. To an extent you're gonna get what you paid for here which isn't quite as much smarts as a fully smart option like a Espertect. So this promises to be able to silence your smoke detector. It's a cool feature because if the smoke detected starts buzzing and you're home and you know you've just burned the toast, you want to be able to shut the thing up without grabbing the towel and starting to wave it all around. So to that end this nifty looking, smart gadget with well designed app is worth your consideration for retro fitting those old smoke detectors. Forcing that with the smart battery.
