10 Best Smart Smoke Detectors 2025 in the United States

The X-Sense Combination Smoke and Carbon Monoxide Detector is a solid choice for anyone looking to enhance home safety with smart technology. This device offers dual protection, detecting both smoke and carbon monoxide, which is a significant advantage for peace of mind. One of its standout features is the talking alarm that indicates the location of the danger, which can be incredibly helpful in a time of panic, guiding users to safety. The interconnected system means that if one unit detects an issue, all units will alert, creating a comprehensive safety network throughout your home.

Connectivity is simple, allowing users to receive app alerts on their phones, which can be shared with family members for added security. The option for a subscription plan that provides professional monitoring and fast emergency dispatch is a noteworthy feature for those who prioritize immediate response in a crisis.

In terms of usability, the design is sleek and unobtrusive, so it fits well with home décor. Plus, installation and maintenance are user-friendly, supported by clear spoken instructions. However, there are a few considerations. The device is battery-powered, which means periodic battery changes are necessary, although the replaceable CR123A battery has a lifespan of about five years. Some users may find the subscription service for enhanced monitoring to be an added expense that isn’t necessary for everyone.

The Kidde Smart Smoke Detector is a solid choice for those looking to enhance home safety with smart features. It uses a photoelectric sensor, which is effective at detecting smoldering fires and generally causes fewer false alarms compared to ionization sensors. This detector is hardwired into your home’s electrical system, ensuring constant power, but it also includes AA backup batteries in case of power outages.

One of its standout features is the ability to send real-time notifications to your phone via the Ring app, so you’ll get alerts whether you’re home or away—this helps you react quickly in emergencies without needing a paid subscription. If you want additional security, there’s an optional monthly plan for 24/7 monitoring. The device connects with other Kidde smart alarms in your home, allowing you to monitor multiple units from your phone, and it integrates with Alexa so you can receive alerts through your smart speaker.

The detector is designed to reduce nuisance alarms, especially those caused by cooking, which can make it less annoying to live with. However, because it’s hardwired, installation might require professional help if you’re not comfortable with electrical work. While the app notifications are handy, some users may consider the optional subscription an extra cost they’d prefer to avoid. This smoke detector is well-suited for homeowners who want reliable, fast smoke detection combined with smart home features and easy remote alerts.

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.
