Google is partnering with First Alert to launch a new smart smoke and carbon monoxide alarm that integrates with existing Nest devices and can be controlled via the Google Home app.

The new First Alert alarms will feature improved Wi-Fi range, audible voice alerts, and an early warning system to enhance safety response times during emergencies.

These alarms will also include automatic safety checkups, early low battery alerts, and the ability to silence alarms through the First Alert and Google Home apps.

While the First Alert model promises a seven-day low battery warning, it will not include the nightlight feature that users appreciated in the Nest Protect.

First Alert emphasizes that modern homes face greater fire risks, making advanced smoke detection features essential.

As Google shifts its focus away from smart home devices, the Nest Protect line is being phased out, although existing units will continue to receive support for the time being.

The Nest Protect, launched in 2013, has been difficult to find, leading to user complaints about stock availability.

First Alert will discontinue its existing Onelink smoke and CO alarms in favor of the new models, which do not support multiple smart home platforms despite the introduction of Matter.

The new First Alert alarms are available for purchase at the Google store and other retailers while supplies last.

Despite the discontinuation of the Nest Protect, Google plans to release new Nest devices in the coming months and years.

In addition to the smoke alarms, Google has delayed the release of the Pixel 9a to April 10, 2025, due to a quality issue.

The company's recent focus has been on AI innovations and Pixel phones, with fewer new releases in the smart home category.
