Nest to introduce a smart smoke detector

The former lead developer of the iPod has now turned his attention to reinventing the thermostat as the latest element of an evolving scheme to automate the home.

Nest should soon be introducing a smoke detector called “Protect,” WSJ alumna Jessica Lessin reported today. Protect will be controlled by smartphone applications or a computer like the company’s Nest thermostat, and Lessin says that it could be paired with a subscription monitoring service that will notify homeowners when it detects smoke or fire.
