Best Overall: Nest Protect

There’s no question about it – if you want a smart smoke detector, Nest is at the top of the game. The Nest Protect has an industrial-grade photoelectric smoke sensor that can distinguish between different types of fires and works with other smart devices in your home such as thermostats or light bulbs according to your preferences. The Nest Protect can be hushed from your phone – no more annoying false alarms! – and alerts your phone to tell you what it thinks is wrong, so you can keep an eye on your home even when you’re far away.

Some of its other features include an occupancy sensor, ambient light sensor and even a humidity sensor to build a complete picture of what is going on in your home. It comes in a wired or battery version and connects to Wi-Fi after a simple set-up process. As a bonus, you can choose from multiple different metallic finishes to complement your home’s décor.

Best Budget: Kidde RF-SM-DC Wireless Interconnect Battery-Operated Smoke Alarm

The Kidde RF-SM-DC may not have all the extra features that some of the other alarms on our list do, but for the budget-friendly price, this device will still give you wire-free interconnectivity quickly and easily. It uses radio frequency to send and receive messages between your smart home system and/or the other alarms in your home. This allows you to update your system in minutes ​so that when one alarm goes off, all the alarms go off. Experts agree that an interconnected alarm system is a superior choice to keep you and your loved ones safe.

Thanks to this Kidde alarm, you can create this interconnected smoke alarm system without spending a ton of money and time to rewire your home. Plus, if you have a smart home hub already like Wink or SmartThings, you can connect your Kidde alarm to it and control it through your hub. A smart touch button quickly hushes the system to silence nuisance alarms.​​​​

Best for Alexa Users: First Alert Onelink Safe & Sound

Have you become best friends with Amazon’s Alexa? If so, this special version of the First Alert Onelink called the Safe & Sound with Amazon Alexa may be the best choice for you. This smart alarm detects fire and carbon monoxide threats in your home, tells you the type and location of the threat and even sends alerts to your phone. However, with its built-in Alexa services, it can also play music, news, or audiobooks through its included high-end speakers. If you have other smart devices in your home, use hands-free voice commands to control lights, locks, thermostats or any other smart devices you may have. The companion app allows you to easily test or silence your alarm, control entertainment devices or adjust the included nightlight using your smartphone or tablet. 

Best Value: First Alert 2-in-1 Z Wave Smoke Detector

The First Alert 2-in-1 Z Wave Smoke Detector is an affordable option if you need multiple alarms throughout your home. This budget-friendly smoke detector and carbon monoxide detector features both electrochemical and photoelectric smoke sensors in order to minimize the risk of false alarms from things such as shower steam. This device can wirelessly link to a z-wave hub such as the Nexia Home Intelligence Hub that helps you control the smart devices in your home and sends alerts to your device if you are away from home. If you do get a false alarm, you can silence the alarm with a touch of a single button.

Easiest Installation: Ring Alarm Smoke and CO Listener

The Ring Alarm Smoke and CO Listener is one of the easiest smart smoke detectors to install because it doesn't actually require you to replace your existing smoke detector. All you have to do is place the Ring Alarm Smoke near your smoke detector, right next to it works just fine. Once it's installed, you can get real-time alarms and notifications to your phone whenever the existing smoke alarm and carbon monoxide alarms sound.

Final Verdict

The best smart smoke detector to buy is the Nest Protect (view at Amazon). It comes with sophisticated sensors, the ability to connect to other smart home devices, and it can be controlled from your phone while providing information about light, occupancy, and even humidity. For a more affordable option, we like the Kiddie RF-SM-DC Wireless Interconnect Battery-Operated Smoke Alarm (view at Amazon). It doesn't have all the high-end features, but it gets the basics down right.

What to Look for in a Smoke Detector

Voice control - When a kitchen mishap causes a false alarm, there’s no need to drag out a stepladder or poke at your smoke detector with a broom to shut it off. Look for a smart smoke detector that includes a voice hush feature, which lets you quickly shut things down in case of a false alarm. Some smart smoke detectors even work with Alexa.

Interconnectivity - This feature allows one smoke detector to instruct the rest of your smoke detectors to sound the alarm. So if there’s a fire downstairs, the smart smoke detectors in your upstairs bedrooms will immediately wake you up. If you have an existing smart home hub, look for smoke detectors that work with the equipment you already own.

Carbon monoxide detection - Some smart smoke detectors are also capable of alerting you to the presence of deadly carbon monoxide gas. This saves you the extra cost and time associated with buying and installing dedicated carbon monoxide detectors.
