Smart Smoke Detector
Android Central

Smoke detectors are a necessary part of any home. They provide peace of mind throughout the night and can help save you and your loved ones in an emergency. For many years we’ve dealt with the high pitched beeps emitted by most fire detectors. But with modern smart fire alarms, like the Nest Protect (2nd Gen), you can swap that out for voice alerts and smartphone notifications. We’ve gathered together a list of the best smart smoke detectors. See which one works for you.

Best Overall: Nest Protect (2nd Gen)

This beautiful looking smoke detector sends messages to your smartphone. It also has a color-changing ring of light and gives verbal notices when there’s a problem instead of emitting shrill chirping noises. If there are multiple of these devices set up in your home and one of them detects danger, it will alert you to a specific location by saying things like, “there’s smoke in the living room.” It will also send a similar message to your smartphone in case you’re away. You’ll always know exactly where the problem is coming from.

In addition to detecting smoke and carbon monoxide, it also has a Split-Spectrum Sensor that senses fast and slow-burning fires, so it will be able to pick up several different dangers. The Nest Protect works with other smart home devices like Hue, Nest, and Wink. For instance, you can make it, so the alarm turns on your home’s smart lights in the event of a fire, thereby making it easier to evacuate safely. You can use the app to turn the alarm off instead of getting up on a chair and attempting to push any buttons.

This detector comes in either a wired or battery-powered version so you can choose the option you like best. Should the battery get low, the device will send a message to your phone instead of chirping the night away. A super helpful addition is the detector’s motion-detecting path light, which gives off a very gentle glow to light the way when you walk beneath it in the dark. This is a relatively expensive fire alarm, which makes it a little harder to purchase one for your entire home. However, the convenience and safety it provides make it well worth the cost.


  • Phone alerts
  • LED indicator
  • Turn off alarms remotely
  • Works with several home automation services
  • Path light

Best Overall

Nest Protect (2nd Gen)

A super convenient smart smoke detector

This fire alarm gives out verbal alerts, smartphone notifications, and visual cues when it detects smoke, carbon monoxide, or a low battery. You can control your device remotely using your app instead of physically interact with it. It even features a motion detector that turns on a path light when you walk under it in the dark. This alarm works with several different home automation services to make a safer environment for you and your loved ones.

Best Budget Alarm: First Alert SCO7CN

If you’re looking for something inexpensive and easy to install, then this is the smart smoke detector for you. It may be reasonable in price, but it still offers vocal, smartphone, and email alerts in addition to the siren whenever it detects smoke or carbon monoxide. If you have multiple of these devices in your home, the notifications will let you know which location is setting off the alarm.

Unlike other inexpensive First Alert smoke detectors, this one doesn’t require a Z-Wave hub to work. So you don’t have to make any additional purchases. It operates using two AA batteries that can be accessed from the side, so you’ll easily be able to swap them out when the time comes. Since this is a much less expensive device, it doesn’t connect to other smart home automation systems, but it will get the job done while making your alarms more convenient.


  • Inexpensive
  • Emails and smartphone notifications
  • No hub required

Best Budget Alarm

First Alert SCO7CN

An inexpensive smart smoke detector

This smoke detector doesn’t cost much, but it still gives you voice alerts, emails, and phone notifications when it detects carbon monoxide or smoke. It’s the perfect fire detector to use if you want something that takes care of the basics without offering any additional bells or whistles.

Best Budget Alternative: Roost Smart Battery

This is the cheapest option for anyone who simply wants to turn their existing fire alarms into smart devices. The battery is Wi-Fi enabled and should the alarm go off it sends alerts to your smartphone so you’ll get a notification no matter where you are. It works with any fire or carbon monoxide detectors that take a 9-volt battery. You can even set it up to automatically alert another person, like a trusted neighbor when you’re on vacation, should the alarm go off.

Since only the battery is smart in this case, you’ll only have the abilities offered by your existing smoke detector. This likely means you won’t have voice notifications or as many lighting cues as other options. Additionally, this battery only links with one smart home automation service, IFTTT. If you use this service, you’ll be able to set it up to do things like turn the lights on when the alarm goes off. This battery lasts up to five years before needing to be replaced, so you’ll get a decent amount of use out of it.


  • Inexpensive
  • Links to IFTTT
  • Smartphone notifications
  • Lasts up to 5 years


  • Limited smart abilities
  • Only works with one home automation service

Best Budget Alternative

Roost Smart Battery

Turn your smoke detector into a smart device

You can turn any smoke detector that takes a 9-volt battery into a smart device using Roost. It’s Wi-fi enabled and will send notifications to your smartphone if the siren goes off. Using IFTTT, connect it with your smart home to have it turn on other smart devices should the alarm sound.

The first thing you’ll notice about this fire detector is that it has Alexa built directly into it. This means you can use the built-in 10-watt speaker to take advantage of hundreds of skills including listening to music, hearing the news, or checking the weather. The other thing you’ll quickly notice is that it’s far more expensive than other options on the market. When you add an Alexa to any device that’s bound to happen, but you get plenty more convenience out of it that way.

Like some other smart sensors on this list, this one sends smartphone notifications and lets you know what the issue is as well as where in your home the problem is coming from. It’ll also give voice alerts and features a color-changing ring to provide you with visual cues if it detects smoke, carbon monoxide, or a low battery. Note that this smoke alarm does require a hardwired connection, which takes more work to install and might not provide the most convenient placement for your Alexa unit.

Something interesting about this device is that it can connect with other brands of smoke detectors that are hardwired into your home. This means it can communicate with
