Remember the original Nest Protect? The company is planning to release a new version with even more features. The new Nest Protect detects and alerts you to the presence of smoke or carbon monoxide throughout your home. It sends you alerts to your smartphone when you are not around. The device lets you know what’s wrong, so you can fix it faster. Multiple alarms can be synced to let you know when one is detecting something wrong.
Nest Protect (2nd Gen) speaks to you with a human voice and tells you the location and levels of smoke and CO. It is wired directly to your electrical system but has a backup battery too. It also has a Pathlight activity sensor to light your way in the dark. You can adjust its brightness from the companion app. The device will cost $99.
