PROS

With a simple battery swap, Roost Smart Battery turns many conventional smoke and CO2 detectors into smart devices that send notifications via Wi-Fi to a smartphone when the alarm is triggered or the battery needs replacement.
Roost is a lot cheaper than replacing all your legacy smoke and CO2 alarms with smart ones.
When a Roost Smart Battery runs out of power, you can re-use its Wi-Fi module on a new and less expensive Roost replacement model.

CONS

Roost Smart Battery lacks the additional smarts of a full-blown smart alarm, such as voice instruction.
If your alarm's siren is hard-wired and battery power is just a backup, you won't be able to silence an alarm remotely.
Roost is more expensive than a conventional 9-volt battery.

It looks like the conventional 9-volt battery used in many smoke and carbon dioxide detectors, but the Roost Smart Battery communicates via Wi-Fi to deliver alerts and low-power notifications to your Android or iOS smartphone. This eliminates the annoying chirping that most alarms emit when a conventional battery is about to run out of power. Based on a lithium cell, the Roost Smart Battery is rated to last for five years. Roost supports IFTTT recipes, which allows it to trigger actions by other IFTTT-enabled devices, and it has announced a partnership with a new ADT security service.
