Pre-order The Roost: A 9-Volt That Gives Smoke Detectors Notifications

Back in January we got our first hands-on with the Roost at CES, but anyone who’s ever used a 9-volt battery is already familiar with the product. The only difference is that this 9-volt includes built-in wifi to give your standard smoke detector the ability to send alerts to your smartphone.

Once paired with a free accompanying app using a clever process where the battery listens for a special coded tone from a mobile device, the Roost plugs into any smoke detector, carbon monoxide detector, or even water leak detector that accepts a standard 9-volt battery. It stays connected to your home’s wifi network at all times, and when it hears the detector’s alarm sound, it automatically sends out a mobile alert to whatever devices you have configured in your Roost account — be it your phone, your partner’s, or even your neighbour’s.

It is hands down the easiest way to add smart features to all the 9-volt powered safety detectors in your home without having to replace them. And the batteries are finally available to consumers from Roost’s website, or Amazon, shipping sometime in September.

Individually they will sell for $US35 each, with no subscription to an online service required. You can also get two-packs at a slightly discounted $US65. Like regular 9-volts the Roost battery will die after a few years, but they thankfully don’t need to be completely replaced. It actually splits in two letting you swap out just the battery section with a $US15 replacement to keep it running.

There’s a good chance that if you were to buy your parents a smart home system, you’d be spending a lot of time on the phone helping them to set it up. But the Roost is designed to be as easy to use as the 9-volt batteries it’s designed to replace.


A Smart 9-Volt Battery Adds Phone Notifications to Any Smoke Detector

There are plenty of smart smoke detectors on the market that connect to your home’s Wi-Fi network to provide smartphone notifications when there’s trouble, but they’re an expensive upgrade to the dumb smoke detector you’ve (hopefully) already got watching over your home. The $US40 Roost promises pretty much the same functionality as those smart alternatives, but on the cheap, upgrading only the 9-volt battery your smoke or carbon monoxide detector already relies on.

Battery life is rated at an impressive five years, even while the Roost is connected to your home’s Wi-Fi network. But that’s because the Roost pretty much sits completely dormant until it detects your smoke detector’s deafening screech. At that point the Roost springs to life, connecting to your home’s Wi-Fi network in order to send notifications to your smartphone.

The Roost is even smart enough to know when its own battery is dying, sending you a notification that it’s time to swap it out before the detector starts its own annoying chirp. And in the final version of the Roost (that’s a prototype pictured above) the bottom half that contains the actual battery can be swapped with a $US10 replacement — giving you five more years of added protection.
