One of the main goals of creating and running a connected smart home is to make everyday life easier and more efficient.
Arguably of equal importance though, is how the smart devices that make up your home contribute to helping keep you and your family safer and more secure.
Welcome to the age of the smart smoke detector.
From a growing range of smart lock solutions to connected security cameras, the variety of devices available to help protect what you care about means there is now more choice than ever when it comes to smart security.
However, another area where intelligent devices are redefining home safety is in the field of smart smoke and air quality detectors.
We’ve taken a look at 6 of the best smart smoke detectors and compared the major features of each, rounding up some of the top options that monitor the quality of the air in your home and let you know when something’s up, wherever you are.
The Best Smart Smoke Detector Systems
If there’s smoke in the air, you want to know that you’ve got a system in place that will pick up the slightest changes and let you know instantly and with complete reliability.
The best smart smoke detectors are designed to let you know the moment something doesn’t seem right, letting you know wherever you are so you can respond instantly.
Nest Protect

Smart home leader Nest are well established in the field of intelligent devices with revolutionary products such as the Learning Thermostat changing the way we interact with our homes, and the Nest Protect is no exception.
The Protect monitors the air in your home for signs of both smoke and carbon monoxide, letting you know (via a voice rather than an alarm) exactly what the problem is and where in the house it’s happening.
If you’re out and about, the companion Nest app lets you know as soon as there’s a problem as well as providing a rundown of detections over the last ten days so you can have a complete overview of your home air quality.

First Alert Onelink Safe & Sound

The First Alert Onelink Safe & Sound delivers a lot of smart technology for the money, combining both a smart smoke detector and an Amazon Alexa enabled smart speaker system rolled into a single smart home fire safety unit.
As a smoke and air quality detector, Onelink Safe & Sound is effectively a hardwired photoelectric smoke and electrochemical carbon monoxide alarm that’s capable of detecting smoke and tracking carbon monoxide levels, providing you with remote notifications via the Onelink Home app at the first sign of danger.
Beyond the smoke detection credentials though, the Safe & Sound is powered by Amazon’s Alexa smart assistant system, meaning that as with other Alexa enabled devices, this smart smoke detector also functions as a smart speaker which will listen out for voice commands or questions, wherever it’s installed.
If you’re looking to create a fully connected (and voice controlled) smart home ecosystem, what this means in practice is that installing a couple of these smart smoke detectors in your home will effectively allow you to extend the voice controlled range of an Alexa-orchestrated smart device setup meaning you’ll be able to control the lights upstairs simply by talking to the smoke detector in your kitchen.
Somewhat uniquely, the Safe & Sound also integrates a high-end omni-directional speaker meaning it’s going to serve you well as a connected audio solution in whichever room you install it.
A 10-year battery backup provides peace of mind and comes as standard with the Safe & Sound providing extra reassurance that your smart smoke detector will always keep home safety as the priority.

First Alert 2-in-1 Z-Wave Smoke & Carbon Monoxide Alarm

If you’re a current (or prospective) owner of a Z-Wave smart hub such as the SmartThings from Samsung, then the First Alert 2-in-1 represents a great choice for a smart smoke detector with out of the box compatibility.
Unlike the Onelink Safe & Sound mentioned above, this smart smoke detector doesn’t include an in-built smart speaker so if you’re looking for a smart detector without this additional functionality, this could be a good choice.
Upon detection of either carbon monoxide or smoke, the First Alert sounds an alarm on the unit itself while simultaneously sending an alert to your smartphone letting you know there’s a problem.
For times when you’re on vacation or away, the First Alert can also be set up to contact any other number of your choice in your absence.

Roost Smart Battery

While clearly not a smart smoke detector in its own right, the Roost Smart Battery makes our cut of the best due to the fact that it lets you transform your existing smoke or carbon monoxide detector into one with simple smart features.
If your detector picks up a problem the battery will let you know via an alert on your smartphone. Roost will also let you know on the app when it’s nearly time to replace the battery so no more intermittent beeps from the alarm when it’s time to switch.
With a life of up to 5 years, the lower price point of the Roost, as opposed to a dedicated smart smoke detector, may make economic sense if you’re happy with your existing devices but are looking to bring them into line with your interconnected home.

Halo Smoke Alarm
When the Halo detects either smoke or carbon monoxide, it will let you know by lighting up the device while a voice tells you that the device has detected something. Simultaneously, the Halo Smoke Alarm will send an alert to your phone so you’ll know if there’s an issue, wherever you happen to be.
With a battery life of up to 10 years, the Halo represents an excellent choice for a traditional-meets-smart smoke and CO detector that will serve as a reliable alarm and air monitor for years to come.
