Most homes these days have smoke alarms installed. They are incredibly important for keeping us safe in our homes, and it's no exaggeration to say that they really can save lives.

However, how many of us can honestly say that we regularly check our smoke alarms—testing that the batteries are still working and that the alarm will sound loud and clear should it need to? Can we put our heads down at night safe in the knowledge that our smoke alarm is protecting us while we sleep?

Smart smoke alarms can change all that. They send you messages and alerts if there's any kind of problem, or if the batteries are running low. Many of them self-test and can give you an all-clear sound to let you know that everything is in perfect working order before you turn in for the night.

Here are the best smart smoke alarms available right now.

Keep your home safe with Nest Protect

$119 $149 Save $30

The Google Nest Protect Smoke Alarm and Carbon Monoxide Detector provides comprehensive smart protection for you and your family. This smart smoke alarm keeps you updated through the Nest App no matter where you are. Plus, you can put a muzzle on the alarm from your phone should a little smoke build up while you cook.

Pros
  • Comprehensive alert system
  • Sensors last for estimated 10 years
  • Instant text alerts
  • Isolates and identifies area of emergency
Cons
  • Price per unit may be prohibitive for some

One of the more popular smart smoke alarms on the market right now is the Google Nest Protect, a smoke and carbon monoxide detector with an impressive range of smart features.

Connect your Google Nest Protect to the Wi-Fi and it will monitor your home for any smoke or carbon monoxide and will tell you exactly where the problem is—allowing you to act quickly in response.

Voice notifications are given to alert you to minor problems, such as smoke resulting from burnt toast for instance. Should you be away from home, alerts will also be sent directly to your phone; to let you know that the alarm is ringing, to notify you of any other problems or simply to tell you that the batteries are running low.

A safety check feature enables you to test your smoke alarm with the press of a button and will provide you with a full report once complete.

The button at its center glows a different color, depending on the current status of the device. Blue signifies that the Nest Protect is active and that all is well. The green light kicks in once the lights are out, to let you know that self-checks have been completed and that your smart smoke alarm will function perfectly overnight.

Yellow light confirms a ‘heads-up’ warning—an alert to a small amount of smoke. This will also be reinforced by voice notifications and/or text alerts so that nothing will be missed. A red light will glow should there be an emergency when smoke or CO in the room has reached dangerous levels.

Lastly, there is a Pathlight feature. If you walk underneath your Nest Protect at night, it will switch on a night light, to allow you to safely traverse the room without knocking anything over, or stubbing your toe on the chair leg! A handy extra feature to stop any bumps in the night.

Best of all the Google Nest Protect houses sensors that have a 10-year lifespan, meaning that once it’s installed, your smart smoke alarm can keep you and your family safe for up to 10 years.

For comprehensive coverage of your home, this smart smoke alarm can give you total peace of mind with a long lifespan to boot.

Onelink Safe & Sound by First Alert 1
Onelink Safe & Sound by First Alert
Best for Alexa

Smart protection for the home with added beats

$220 $278 Save $58

The Onelink Safe & Sound by First Alert offers all the safety features you expect from a smart smoke detector, with all the functionality of Alexa to boot. Whether you want to listen to music, catch up on your favorite podcast, or just want instant alerts for potential smoke and CO danger in your home, Onelink has you covered.

Pros
  • Instant notifications
  • Connects with other hardwired alarms
  • Built-in smart speaker may appeal to some buyers
Cons
  • Could be seen as something of a novelty item for a serious purpose

The First Alert Onelink Safe and Sound offers something a little bit different than other smart smoke alarms out there, including everything you could reasonably expect from a smart smoke and carbon monoxide alarm, plus a built-in smart speaker that works with Alexa.

Use this smart smoke alarm to talk to Alexa, play music or podcasts from your favorite streaming sites, or listen to the next chapter of your audiobook while you cook. The built-in omnidirectional smart speaker function sets this device apart from other smart smoke alarms out there.

Whether this extra functionality is something you would want from this type of device will be entirely up to you.

Now that the sound aspect has been covered, what about the safety bit? Well, this is also a smart smoke and carbon monoxide alarm that you can track from your smartphone.

Text alerts and remote notifications will be sent to your phone, should any danger be detected that triggers the alarm. You can use the app to review the current carbon monoxide levels in your home and customize nightlights, as well as all the usual features such as battery life, self-check results, and so on.

Voice alerts are also provided in the event of minor (and major) emergencies, helping you to identify danger zones, and take correct and appropriate action.

First Alert’s Onelink Safe and Sound smart smoke alarm also boasts its ability to connect to any other hardwired alarms in your home—including other branded devices. This will then allow notifications to be sent to your phone for any of these connected devices.

You might argue that a smart speaker function built into a smart smoke alarm is a trifle unnecessary, given the main purpose of a smoke detector. But for anyone who has yearned for this extra feature to be included, the search is over!

Aegislink
Aegislink Wireless Smart Fire Smoke Alarm
Best Value

Smart functionality without the hefty price tag

The Aegislink Wireless Smart Fire Smoke Alarm is an affordable alternative to protect your home against smoke and carbon monoxide. Using its built-in photoelectric sensor, this smart smoke alarm performs routine maintenance checks to ensure proper protection around the clock.

Pros
  • Affordable
  • Has all essential functionality you would expect from a smart smoke detector

  • No voice alerts

At the budget end of the best smart smoke alarm is the Aegislink wireless smart fire and smoke alarm. Offering the main features required from a smart smoke alarm for a fraction of the price, this is a very affordable option for people trying to safeguard their homes on a budget.

Compatible with either the TuyaSmart or Smart Life apps, this device will send you all the remote notifications you would wish it to—direct to your smartphone. Use the app to silence any unwanted alarm sounds too.

As with many other models, this Aegislink device will self-check itself regularly to ensure it is functioning as it should. Sensors, electronics, and battery life will be tested approximately every 60 seconds as a failsafe.

Designed with advanced photoelectric technology, it can detect any kind of smoldering fire in a matter of seconds and will alert you instantly upon detection. Aegislink advises that one of these devices can effectively cover an area of 215-430 square feet—which gives you a good indication of whether one or more would be required for your own home.

Onelink Smart Smoke Detector
Onelink Smoke Detector and Carbon Monoxide Detector
Best for HomeKit

Smart protection and easy installation for Apple households

The Onelink Smoke Detector and Carbon Monoxide Detector is an Apple HomeKit-enabled and battery-powered smart smoke detector. Mobile and voice alerts keep you abreast of danger anywhere, anytime.

Pros
  • Works well with Apple HomeKit
  • Compatible with Alexa for device status updates
  • Voice alerts locate source and nature of threat
  • Easy installation
Cons
  • Expensive for a single unit

The Onelink Smart Smoke Detector is a two-in-one smoke and carbon monoxide alarm that alerts you to both types of danger in your home. Boasting a photoelectric smoke sensor and electrochemical monoxide sensor, you receive smartphone notifications if a threat is detected, and voice alerts to confirm the location of the danger.

This is a battery-powered unit that requires no hardwiring to install. You’ll need Wi-Fi with 2.4 GHz and access to the Onelink Home App to operate the device. Once installed, it can wirelessly connect with any other hardwired alarms that you may have installed and can be integrated as part of a smart home network without the need for rewiring.

Onelink is compatible with both iOS and Android devices and is somewhat compatible with Alexa, too. That is to say, you can ask Alexa to check in on the status of your alarm at any time. However, Onelink is better paired with Apple HomeKit, which offers broader functionality as part of a smart network.

The alarm itself sounds at a more than audible 85 decibels, so unless you’re away from home, you needn’t worry about being able to hear it. Using the Onelink App you can silence the alarm remotely, or notify the emergency services, depending on the cause of the alarm. It will notify you when the batteries are running low, and an easy access door makes the changeover nice and simple.

Siterwell smoke alarm
Siterwell WiFi Smoke Detector
Best Smart Assistant Alternative

Standalone smart protection for the home

$96 $125 Save $29

Pros
  • Easy to track device via smartphone
  • Real time notifications
  • Sensors detect if threat is smoke or CO related

As well as sending you the usual text alert notifications, this smart smoke alarm also features unique voice alerts. High-powered sensors help the device distinguish between threats of smoke or carbon monoxide, and the voice alerts will sound accordingly. You’ll be notified if the alarm is sounding for smoke or fire, or if the alert is for CO instead.

The idea behind this feature is that in an emergency, it will help to reduce panic, by providing a clear warning as to the nature of the problem.

A solid Wi-Fi connection enables easy smartphone tracking of this smart smoke alarm. Monitor your device’s control detector via the app, to keep tabs on the CO alarm, smoke alarm, battery life, voltage levels, test alarms or to check when the device is reaching the end of its life and needs replacing.

Nuisance alarms can be minimized with this smart smoke alarm too, as its photoelectric smoke-sensing technology can detect slow smoldering fires quickly. So, you needn’t worry about your alarm tripping every time there’s a bit of smoke from cooking in the kitchen, for example.

This smart smoke alarm can also test itself and notify you if there are any of its features that are failing.

There is plenty to consider with this Siterwell Wi-Fi smoke detector if you’re looking for a smart smoke alarm to protect your home.

Kidde Smart Smoke Detector
Kidde Smart Smoke Detector
Best Dual-Pack Option

Two-for-one smart smoke detector protection for the home

$114 $123 Save $9

For those looking to install multiple smart smoke detectors throughout the home, the Kidde Smart Smoke Detector dual pack offers an excellent value. With voice alerts and LED color coding, it's easy to tell what your Kidde smoke alarm is alerting you about.

Pros
  • Compatible with Alexa and Google Home
  • Receive smart notifications and voice alerts
  • Remotely silence alarm with the Kidde App
  • Pack includes two smart smoke detectors
Cons
  • No carbon monoxide detector

There’s no carbon monoxide detector built into this Kidde Smart Smoke Detector, but don’t let this put you off. This Wi-Fi-enabled smart smoke detector has plenty to offer. It is compatible with Alexa and Google Home, and the Kidde App makes setting up either one a doddle.

Once installed, the Kidde App sends real-time notifications if the alarm is triggered and it can also be used to test the functionality of the alarm, too. Notifications can be sent to multiple household members as well, as an extra safeguard, and a voice alarm will sound to announce the nature of the hazard. This is in addition to the 85-decibel alarm itself.

It uses photoelectric sensor technology to detect visible fire particles associated with smoldering fires and has LED warning indicators that provide an easy visual reference to the current alarm status.

This is a hardwired alarm, so buyers beware there will be a lengthier installation with this one. However, on the plus side, the sealed backup battery is guaranteed for 10 years and protects during power outages. And with two smart smoke detectors included in this package, you’re already well on your way to an integrated network for the home.

Ring Alarm Smoke and CO listener
Ring Alarm Smoke and CO Listener
Best Alternative Option

A very good listener

The Ring Alarm Smoke and CO Listener is a smart device that monitors your existing smoke alarm and sends you real-time notifications if the alarm is triggered.

Pros
  • Cheaper than some smart smoke alarms
  • Doesn't require a complete overhaul of alarm setup at home
  • Provides instant text alerts
Cons
  • Cannot independently detect smoke or CO
  • Dependant on a fully functioning separate smoke alarm in order to work

Not a smart smoke alarm per se, but rather a companion device intended to work in conjunction with your existing (non-smart) smoke alarm.

You may already have smoke alarms already installed throughout your home and may not wish to spend valuable time and currency on replacing them all.

However, if this is you, you may also wish to consider the Ring Alarm smoke and CO listener instead—as it effectively gives you access to some of the functionality associated with smart smoke alarms, without the need to drastically change the setup in your home.

This device sits alongside your existing smoke alarm or carbon monoxide detector and will alert you via your smartphone if the alarm is triggered.

It cannot detect smoke or rising CO levels itself, but will ‘listen’ to any alarm it is installed next to.

The obvious problem with this device is that its effectiveness depends entirely on the maintenance and upkeep of the already installed alarms. If they are defective in any way, then the Ring listener cannot do its job properly.

Nevertheless, you may feel that this is a more cost-effective solution to boosting your home security without breaking the bank.

Choosing the Right Smart Smoke Alarm for You

Naturally, choosing the right type of smart smoke detector depends on a few factors. Do you want your smart smoke detector to double up as a carbon monoxide detector? How many are you looking to install throughout the home, and where? Are you interested in a hardwired or battery-powered option? And do you want it to work alongside any existing smoke alarms that you may already have installed?

Moreover, what type of smart functionality are you looking to get from it? Perhaps you just want an easy way to silence the smoke alarm while cooking, or maybe you want to integrate it as part of a smart home network that works with your voice assistant. Considering each of these factors will inform your choice of smoke detector.

For a voice assistant-enabled smart smoke detector with plenty of extra functionality, the First Alert Onelink Safe & Sound is a great choice. A powerful smart smoke and carbon monoxide detector that offers real-time notifications, works with iOS or Android, and allows for the alarm to be shut down remotely in the event of a false alarm. It also features an integrated Alexa-enabled Bluetooth speaker for added pizzazz.

If you're looking to save a few bucks without having to compromise too much on functionality, something like the Aegislink Wireless Smart Fire Smoke Alarm will serve you well. It offers a reasonable area of coverage per alarm and provides remote notifications in the event of an emergency. It's relatively simple to install, and offers reliable protection against smoke and carbon monoxide, at an affordable price. Plus, if you're looking to install smart smoke detectors throughout the home, it's one of the most cost-effective options.

However, if you're looking for the best that money can buy, the Google Nest Protect Carbon Monoxide Protector is still comfortably top of the pile. Voice Assistant compatible, it can be integrated as part of a complete smart home network. In the event of smoke or carbon monoxide detection, it will identify the area and source of the problem, and send instant alerts to your phone. It conducts automatic safety checks and provides reports direct to your smartphone, once it has completed its diagnostics. LED indicators provide an at-a-glance update on their current status, letting you know if all is well or if there is a problem. Plus, it has a 10-year lifespan, making it a good investment for protecting your home in the long run.
