Smart Smoke Detector
Smoke detectors are a necessary part of any home. They provide peace of mind throughout the night — and all day long — and can help save you and your loved ones in the event of 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 out those piercing noises for voice alerts and smartphone notifications. We’ve compiled a list of the best smart smoke detectors so you can see which one works for you.
Best Overall: Nest Protect (2nd Gen)

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 including Hue, Nest, and Wink. For instance, you can program 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 also 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

With a four-year battery life using the included CR123A batteries, it is certified to work with most ZigBee-enabled hubs. The multi-color LED changes based on the state of the device.

Best for Basics: Kidde Smoke/Carbon Monoxide Alarm
Easy to install, and taking the place of two devices, the audio alarm blares at 85 dB at up to 10 feet to ensure you can hear it, even if you’re fast asleep in the middle of the night. You can activate the Hush feature to temporarily silence the alarm if you just burned something on the stove and you’ve tended to the issue already. There’s a test/reset button and LEDs. It flashes green for normal and red if there’s an issue like the batteries are low. It can operate in extreme humidity, from 10 up to 95 percent and in temperatures from 40 degrees Fahrenheit up to 100.
Since it runs on traditional batteries (three AAAs, included), the detector will continue working, even if there’s a power outage.
- Takes the place of two devices
- Audible message warnings
- Keeps functioning even in power outages

Source: First Alert
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 other fire alarms, so you don’t have to purchase one of these for every room in your house. Just get it for the places that you are most likely to take advantage of Alexa’s skills.
- Built-in Alexa
- Smartphone alerts
- 10-watt speaker

Smart and alert
Smart smoke detectors are a worthwhile addition to any smart home set-up, and there are several different smart smoke detectors on the market from which to choose. Many of these devices tend to be expensive, so you’ll want to consider whether the conveniences offered by the smart detector makes the purchase worth it – especially if you decide based on the size of or floors in your home that you’ll need more than one.
To go truly smart, you’ll want something that can send you smartphone notifications. There are also simpler smoke detectors that are smart in that they either provide voice notifications or even just can communicate with one another wirelessly. Still, I highly advocate getting something that also features a visual cue and can be turned off remotely via an app.
My highest recommendation when it comes to the best smart smoke detectors is for the Nest Protect (2nd Gen), which gives vocal alerts, has a ring that changes color, and sends phone notifications should it detect a problem. It will even tell you what the problem is and what room to find it in. It also works with several home automation services and devices, so you can link it to say your smart lights and have them turn on if a fire is detected.
