Google transitions Nest Protect users to new smart home devices

Google Discontinues Nest Protect, What’s Next?

Google announced in 2025 that it was ending Nest Protect, its best-selling smart smoke and carbon monoxide detector. That move also includes the Nest x Yale Lock, another departure from Google-labelled home safety devices.

Remaining Nest Protect units are still available, but only while supplies last. Google has already started migrating platforms and launching replacement products. If you own either of these devices, now’s the time to plan your next steps.

A Quick Glance At Nest Protect

Nest Protect debuted in 2013 under Nest Labs and quickly became one of the best-known smart safety devices. Shortly after, Google bought the company, making the product a household name. It provides smoke and carbon monoxide detection in one small package.

What set Nest Protect apart was how it meshed with the rest of the smart home. It provided voice warnings, Wi-Fi connectivity, and pushed mobile alerts in case of emergencies. Users loved its dependability, simplicity, and years of uninterrupted updates from Google’s support teams.

Reasons Behind the Discontinuation

Google’s move indicates an increased focus on collaborating with third-party makers such as Yale and First Alert. By reducing its hardware product lines and working more with third-party specialists, Google appears to be emphasizing collaborations over in-house manufacturing. This approach may align with a broader shift toward software, interoperability, and ecosystem integration

The primary goal is to improve compatibility between devices using Matter, a smart home standard. Through simplification of its product lineup, Google will be in a position to reduce complexity and improve user experience. This also provides greater freedom for consumers in constructing their smart homes with goods from various manufacturers.

What Becomes Of The Current Nest Protect Devices?

If you already have a Nest Protect, it will keep functioning until the device’s expiration date. For the second-generation model, that is usually 10 years from the date of manufacture. The first-generation model lasts seven years. Google will issue updates and security patches as necessary during that period.

Users will get notified as their devices are nearing expiration. Notifications can pop up as mobile push alerts, app notifications, or status light indicators. After the expiration date, the device must be replaced to ensure safety levels are maintained.

Switch to First Alert Smart Smoke and CO Alarm

As Nest Protect departs the market, Google has teamed up with First Alert to launch a new smart alarm. The new product not only detects smoke and carbon monoxide but is also fully integrated into the Google Home app. The transition is designed to make it simpler for users to depart from Nest-labelled hardware.

The First Alert Smart Smoke and carbon monoxide alarm supports smart features like voice alerts and detailed mobile notifications.

Features of the First Alert Smart Smoke and CO Alarm

The First Alert Smart Alarm offers 2-in-1 protection against carbon monoxide detection and smoke. It uses Precision Detection technology to help reduce the frequency of false alarms from common sources like cooking. 

This device includes a 10-year sealed battery, eliminating the need for replacements. The consumers are offered an option between battery and hardwired installations, depending on their home setup. It integrates directly with the Google Home app for alerts and status notifications.

Nest Protect vs First Alert Smart Alarm

Both the First Alert Smart Alarm and the Nest Protect provide solid smoke and carbon monoxide detection, but there are a few distinct differences. Nest Protect has been in existence for more than a decade, building trust through app notifications and voice alerts. It works well with Google Home but not with Matter.

The First Alert Smart Alarm provides new features such as a sealed 10-year battery and optional wireless interconnect. It is more expensive but brings new functionality and future-proofing.

The Role of Matter in Smart Home Devices

Matter is a global standard developed to enhance smart home compatibility. With Matter, users can install and control devices in Apple HomeKit, Google Home, Amazon Alexa, and SmartThings more simply. It minimises the use of multiple apps and complex pairing procedures.

Matter-enabled devices can talk to one another reliably, no matter the brand. Both the First Alert Smart Alarm and Yale Smart Lock are Matter-enabled. This allows users more freedom when planning their smart homes and keeps their devices compatible as platforms change.

Yale Smart Lock with Matter, The Successor to Nest x Yale Lock

Alongside Nest Protect, Google is discontinuing the Nest x Yale Lock. Replacing it is the new Yale Smart Lock with Matter, which retains the full-deadbolt design while adding improved smart features. It works with the Google Home app and also supports other platforms via Matter.

The Yale Smart Lock includes a keypad and keyway, allowing multiple access methods. It also supports app-based customisation, auto-lock settings, and guest codes. With its sleek design and platform flexibility, the new Yale Smart Lock is a strong follow-up to the Nest-branded version.

Migrating from Nest App to Google Home App

Google has been shifting users from the Nest app to the Google Home app for some time. This migration is now more important than ever as new devices are no longer supported in the older Nest interface. Features from Nest are being integrated into Google Home gradually.

Users can look forward to improved support for Matter devices, more automation capabilities, and a more integrated control panel. The update does take some learning, but the payoff is a more cohesive smart home experience. Google advises everyone to transition to the new app as soon as possible.

What Should Users Do Now?

If you have a Nest Protect, check its manufacture date to confirm when it expires. Keep using it until that time, and ensure you receive app notifications as it nears replacement. After expiration, the device must be replaced for continued protection.

Google encourages users to explore Matter-compatible options like the First Alert Smart Alarm. For smart locks, consider switching to the new Yale Smart Lock. Also, migrate your smart home management from the Nest app to Google Home for ongoing support and access to new features.

Safety and Compliance Considerations

Carbon monoxide and smoke detectors have certified expiration dates for a reason. Over time, sensors lose effectiveness. It’s critical to replace any expired devices to maintain home safety and meet compliance standards.

Google will provide notifications before expiration and offer guidance for replacing your device. Once a Nest Protect expires, it should be taken out of service. Testing devices regularly and keeping up with app updates are key steps in protecting your household.

First Alert Smart Alarm, Technical Specifications

The First Alert Smart Alarm features advanced detection for both smoke and carbon monoxide. It uses updated sensors to detect synthetic materials and differentiate real threats from false alarms. That means fewer unwanted interruptions while still ensuring safety.

It includes a sealed lithium battery designed to last ten years without replacement. Options include battery-powered or hardwired installation, with some models offering voice alerts and wireless interconnect. All models meet the latest safety standards and integrate with the Google Home app for real-time alerts.

Smart Home Ecosystem Integration

Google’s approach to smart home hardware is changing, but its focus on software and integration remains strong. The First Alert and Yale devices are designed to work seamlessly within the Google Home ecosystem. Users can monitor status, control functions, and set automations through one app.

Because Google and its partners are emphasizing Matter as a universal standard, the Yale lock is being marketed with Matter support, and First Alert is positioning its alarms to be future-ready.

However, First Alert SC5 devices do not have native Apple HomeKit support as of now. Users should verify platform compatibility before expecting universal interoperability.

Availability and Pricing

The First Alert Smart Smoke and CO Alarm is priced at $129 and will launch in late 2025. It will be available in both the United States and Canada. Users can purchase it through online stores, local retailers, and Google’s partner channels.

The Yale Smart Lock with Matter will also be available in multiple finishes to match different home styles. If you’re planning a smart home upgrade, now is the time to evaluate replacement options.

Support and Warranty for Existing Nest Protect Users

Google will continue to support existing Nest Protect devices with software and security updates until their expiration date. Warranty coverage will also remain in place for users with active warranties.

For those transitioning to new devices, Google offers help articles and support through the Nest Help Centre. Users can also contact support for assistance with app migration, product selection, or general troubleshooting.

The Future of Smart Home Safety With Google and Partner

Google’s partnerships with First Alert and Yale represent a shift toward better hardware through collaboration. Instead of developing everything in-house, Google is leaning on expert brands to deliver specialised safety solutions.

This focus on interoperability, Matter integration, and user experience is shaping the next phase of smart home development. Regular product updates and new features will continue rolling out through Google and partner brands.
