The Roost smart battery adds iOS/Android notifications to your old smoke detectors for $35, pre-order now

roost-wifi-batteryThe Roost smart battery cleverly disguises itself as a typical 9V battery. But it’s so much more. This battery can send notifications to your iOS or Android device whenever your smoke or CO alarm goes off. The best part is that it doesn’t require you to replace your old detectors. Instead, you just pop the Roost battery into your existing detectors and you’re good to go.

It works 24/7 and doesn’t require a subscription of any kind. You can even allow friends and family receive notifications as an extra layer of protection for when you’re out of town.

Each Roost is equipped with a replaceable lithium battery pack that lasts about 5 years. You’ll get an alert letting you know when the battery is on its last legs and then you’ll have to order a replacement for $14.99.

Late last year Roost took Kickstarter by storm and then made a splash a few months later during CES. Now, Roost is finally ready for primetime: pre-orders are now open at Amazon with a September release. A single Roost will cost you $34.99, while the 2-pack offers a slight discount at $64.99.
June 24, 2015 – It’s a very exciting day for all of us here at Roost because starting today, you can pre-order the Roost Smart Battery for smoke alarms directly on We’ve spent a long time engineering a product that we’re extremely proud of, and we’re so happy to finally share it with you.

If you’ve been following along with us, you already know that the Roost Smart Battery looks just like a familiar 9V battery. It’s inexpensive and easy to use, and transforms your existing 9V smoke and CO alarms into smart alarms.

How does it work? Just swap the 9V battery in your alarm with a Roost Smart Battery—seriously, it’s that easy—and you’ll get notifications on your smartphone via the free Roost app whenever your smoke or CO alarm sounds.

Yup, say goodbye to those pesky low battery chirps at 3AM from your old smoke alarm battery; Roost notifies you before the chirping ever begins. Plus, Roost Smart Batteries last more than five years in typical smoke alarms; five times longer than regular 9V alkaline batteries.

Today we’re also unveiling our new website (check it out!) along with the brand new Roost Smart Battery design at our booth at CE Week today in NYC.
