A new WiFi-capable 9 volt battery promises to turn your old smoke detector into a potentially life-saving piece of smart home equipment.
The Roost 9V battery works in conjunction with an app on your smartphone.
Once you set it up, the battery will send a notification to your smartphone when it’s running low on power. That means no more middle of the night chirping from your smoke detector to alert you to low battery power.
It will also send an alert to your smartphone if the smoke detector sounds when you’re not home.
You can choose friends or family members to receive alerts as well should the alarm sound. You can also silence a false alarm with one tap on the app instead of pulling the battery out of your smoke detector when you burn toast and possibly forgetting to replace it later.
It works with existing smoke detectors and connects to your home WiFi. It comes with a replaceable lithium battery pack that Roost says should last for another five years. This smart battery isn’t cheap, it costs $35, but that’s not bad for a smart smoke detector.
The device will be available starting in September. One note about smoke detector in general. Remember that they don’t last forever. So not only should you replace the batteries when you set the clocks forward and ahead, you should replace your smoke detector every few years.
