Google Home's Public Preview environment is preparing to deliver an update that expands support, features, and device control. Enrolled testers will soon experiment with third-party Matter support for smart locks and the addition of Nest Protect CO/smoke alarms.

Starting in the Public Preview, the Google Home app is finally adding support for the Nest Protect, as well as Matter-certified smart locks.

If you've got a Nest Protect smoke and CO detector, now's your chance to fully integrate it with your Google Home setup.

The smoke and CO alarm is finally coming to the Home app, along with increased functionality for smart locks connected to Google Home via Matter

For years, owners of Google’s Nest Protect smoke detector have been asking when their devices would make the leap from the older Nest app to Google Home, and the answer was always the same: one day, maybe.
