Enjoy complete peace of mind at home with the Nest Protect smart alarm. It’s a smoke and carbon monoxide detector in one, so you can rest assured that all fumes will be monitored. This alarm can detect varying levels of smoke, so when you’ve burnt the toast you’ll get a calm voice alert instead of the full siren. It sends notifications directly to your phone, and you can turn it off remotely too – no more towel wafting required! It automatically tests its own batteries and sensors, and its 10 year lifespan means you’re protected for the long term. Plus, it has an integrated light with motion sensor, so it’ll gently illuminate your path at night when you need a glass of water.
