Will the last device leaving the Nest app please turn out the lights? The day finally arrived; Google has announced it’s transitioning the Nest Protect smoke and CO alarm to the Google Home app. This means you’ll be able to get alerts and notifications for your alarm directly through Google Home, as well as hush alarms, according to a blog post from Google. This means you no longer need the Nest app for any device, but you can still use it — for now, at least.

The Nest Protect was the last device that could only be accessed and controlled from the Nest app, following Google’s efforts over the last couple of years to fully port its Nest cameras and other devices to the Home app. With this move, Google will finally be able to sunset the Nest app, although the company has said it will keep it in maintenance mode indefinitely.

The new function for the Nest Protect is coming to Google Home users in Public Preview on Android this week and to iOS “soon.” According to Google, it will enable the following features:

Receive emergency and heads-up notifications for smoke and carbon monoxide

Get critical status alerts like battery health or device issues

View when alarms were last tested and run a system-wide safety checkup.

Create a schedule for automatic sound check testing when you’re away from your home

Modify your configuration: change system-wide and alarm-specific settings

View your camera live feeds directly from the emergency alarm card

Alongside the Nest updates, the Google Home app is also getting expanded support for smart locks connected via Matter, adding the ability to set passcodes, among other features. The lock updates are rolling out through the app’s “Public Preview” feature on Android, with iOS support coming in early 2025.

This will allow more manufacturers’ locks to work with Google Home and bring more functions to the app, including passcode management and automatic locking. Google says that not all of the features will work with all Matter locks; it depends on the lock manufacturer. Here’s a rundown of what will be added:

Passcode Management: You’ll be able to manage who has access to your home by sharing and editing passcodes with ease to household members and guests.

One-tap entry: You can enable one-tap entry instead of typing in your passcode and you can lock/unlock your door remotely from the Home app with just a tap of a button.

Automatic locking: Choose how long your lock should wait before automatically re-locking.

Vacation Mode: This mode locks the keypad so it can’t be unlocked from the outside using the touchpad.

One-touch locking: Lock the door using the touchpad or button on the lock.

Push notifications for lock events
