10 Best Smart Smoke Detector 2025 in the United States

The Kidde Smoke & Carbon Monoxide Detector is a reliable, battery-powered device that provides dual protection against both smoke and carbon monoxide. One of its standout features is the 10-year battery life, which eliminates the hassle of frequent battery changes and potential low battery chirps. This can save you some money over the life of the detector. The device uses advanced sensing technology to reduce false alarms, especially those that can occur during cooking. It also adheres to the latest safety standards, providing an extra layer of reassurance for users.

The LED indicators (green, amber, and red) clearly display the alarm status, making it easy to understand whether the device is operating normally or if there's an issue. Installation is straightforward due to its battery-powered design and twist-and-click mounting system, which means no need for electrical wiring. Additionally, the self-testing alarm feature checks its internal components regularly, although you should still perform a manual test weekly.

On the downside, since it lacks connectivity features like Wi-Fi or smart home integration, it may not be suitable for users looking for a more connected and automated home security system. Also, while the 10-year battery life is impressive, it’s important to note that this is not a performance guarantee but rather a typical lifespan. This product is ideal for users looking for a straightforward, easy-to-install smoke and carbon monoxide detector with minimal maintenance and reliable performance over a long period.

The Kidde Hardwired Smoke & Carbon Monoxide Detector is a reliable choice if you're looking for a device to alert you to both smoke and carbon monoxide with one unit. It uses photoelectric and electrochemical sensors, which means it can detect smoke and dangerous CO levels effectively. Since it is hardwired into your home's electrical system with a 10-year battery backup, you won't need to worry about changing batteries frequently, which adds convenience and lowers long-term costs.

The device includes clear voice alerts that announce "Fire!" or "Warning! Carbon Monoxide!" so you can react immediately without confusion. Another plus is the interconnect feature: if one alarm goes off, all connected alarms will sound, helping to alert everyone in your home quickly. The detector also has LED lights to show its status, and it performs self-tests to ensure it's working properly, though you should still manually test it weekly. Installation requires wiring into your home's ceiling, so it might be best handled by someone comfortable with electrical work or a professional. The product is designed to reduce false alarms caused by cooking, which is helpful in avoiding unnecessary stress.

One small downside is that the warranty covers the alarm for 10 years but doesn't guarantee battery performance for that entire time. Also, while it’s a smart detector in terms of alerts and interconnectivity, it doesn’t have Wi-Fi or app integration, which some other smart detectors offer for remote monitoring. This product suits homeowners who want a dependable, long-lasting alarm that covers both smoke and carbon monoxide detection with straightforward alerts and minimal maintenance.

This 6-pack smart smoke detector from Soewolit is designed to offer reliable, long-term fire safety for homes or RVs. It uses a photoelectric sensor, which is great for detecting slow-smoldering fires, making it well-suited for early warnings. The detectors connect to your home’s 2.4GHz Wi-Fi network and send instant alerts to your phone through the Smart Life or Tuya app, keeping you informed even when you’re away.

Each unit is powered by a replaceable lithium metal battery that lasts up to 10 years, meaning less hassle with frequent battery changes. With an 85dB alarm, the sound is loud enough to alert you effectively. Installation is straightforward, with options to mount on walls or ceilings, and there’s a handy test button plus mute feature accessible both on the device and via the app. On the downside, the detectors rely on a specific nonstandard battery type, which you’ll need to replace after 10 years, and they only work on 2.4GHz Wi-Fi, so they won’t connect to 5GHz networks.

The compact, modern design is unobtrusive but might be smaller than some users expect. This pack of six offers good value for larger homes or multiple locations, providing peace of mind with easy maintenance and smart connectivity. For those seeking a smoke detector that combines dependable detection with convenient phone alerts and a decade-long battery life, this could be a solid choice.
