Google Nest 120V Hardwired Combination Smoke and Carbon Monoxide Detector with AA Battery Backup and WiFi Connectivity - 2nd Gen

After revolutionizing the way that people saw thermostats, Nest Labs turned their attention to the oft-maligned smoke detector. With the Nest Protect smoke and carbon monoxide alarm, they set out to design a friendlier, more effective home safety solution. By all measures, they succeeded wildly. With two levels of alarms, two types of alarms, three safety sensors, three activity sensors, and a communicating LED ring, the Protect is equipped to help you handle all manner of fire emergency. Getting protected is easy; the straightforward installation can be handled by any homeowner, and the free mobile app will guide you through setting up the Protect and designating an installation location. The only thing better than installing a Nest Protect is installing multiple Nest Protects, as these devices communicate with each other and share data
