10 Best Smart Smoke Detectors 2025 in the United States

The Kidde Smoke Detector & Carbon Monoxide Detector Combo is a dual-function device designed to enhance home safety by detecting both smoke and carbon monoxide. It features a photoelectric sensor for identifying slow, smoldering fires and an electrochemical sensor for detecting carbon monoxide, providing comprehensive protection. The 85-decibel alarm and red LED alert users to any hazards, ensuring they are promptly informed.

One of the key advantages is its 10-year lithium battery, which eliminates the need for battery replacements and maintains functionality even during power outages. The Test-Hush button is convenient for regular testing and silencing false alarms, such as those caused by cooking or steam from showers. Installation is straightforward as the alarm automatically activates when mounted, with no need for pull tabs or switches. Additionally, the device will chirp at the end of its life cycle, indicating it needs to be replaced.

However, this smoke detector lacks smart home integration, which may be a drawback for users looking to connect it to a broader home automation system. Its reliance on battery power only, without a backup hardwiring option, might also be a concern for some. Its ease of use, dual detection capability, and long battery life make it a solid choice for those looking for a reliable and efficient smoke and carbon monoxide detector.

The FIRST ALERT BRK PRC710V is a dual-function smoke and carbon monoxide alarm that utilizes both electrochemical CO sensing technology and photoelectric smoke sensors. This combination ensures accurate detection of both smoke and carbon monoxide, minimizing false alarms and providing peace of mind. One of its standout features is the built-in 10-year battery, which eliminates the need for frequent battery replacements and complies with various U.S. state regulations.

Additionally, it includes a voice alert system that clearly states whether the danger is smoke or carbon monoxide and indicates the specific location from a preprogrammed list of up to 11 locations in your home, making it easier to respond to threats quickly and efficiently. Installation is straightforward, thanks to its easy-to-mount design and included mounting bracket. The low-profile design helps it blend seamlessly with home decor.

However, this alarm does not offer smart home integration, which might be a drawback for those who are looking to connect their safety devices to a broader home automation system. The alarm relies solely on audible alerts and voice notifications, which are loud and clear but may not be sufficient for individuals who are hearing impaired. This device is best suited for those looking for a reliable, low-maintenance smoke and carbon monoxide detector without the need for smart home features.

The Kidde Smart Smoke and Carbon Monoxide Detector is a solid choice if you want reliable protection against both smoke and carbon monoxide. It uses photoelectric and electrochemical sensors, which are good at quickly detecting smoke and CO. The device is hardwired for power, making it dependable without worrying about changing batteries, though it includes AA batteries as a backup.

One of its key strengths is the real-time alerts sent to your phone through the Ring app, so you’re notified even when you’re away from home without needing a subscription. You can also connect it with Alexa devices for voice alerts. It claims faster smoke detection than some competitors and features technology to reduce false alarms caused by cooking, which can be annoying with some alarms. The smart connectivity allows you to link multiple alarms in your home, so you get notifications from all of them on your phone, which is great for larger homes.

Full 24/7 professional monitoring requires an optional paid Ring subscription, which adds to the cost. The alarm is certified to meet safety standards, which is reassuring. On the downside, since it is hardwired, installation might require professional help if you’re not comfortable with wiring. Also, it supports only the Ring app, so if you prefer other smart home platforms, compatibility is limited. If you want a dependable, smart smoke and CO detector with good app alerts and smart home features, this Kidde model fits well, especially for users already using or open to Ring products.
