Thoughtful, not annoying. Nest Protect checks itself over 400 times a day and lets you know if something is wrong. It also has Steam Check, so a nice, relaxing shower shouldn't cause your alarm to shout at you. And Pathlight, so it can light your way at night
Easy to install. Nest Protect only takes minutes to set up with your iOS or Android device. Once you've added each of your Nest Protects to your Nest account, they will automatically connect to each other. Nest Protect is also simple to attach to the ceiling, thanks to a neatly designed back plate
