10 Best Smart Smoke Detectors 2025 in the United States

The X-Sense Smart Smoke and Carbon Monoxide Detector Combo is designed to enhance home safety with a focus on ease of use and connectivity. One of its standout features is the interconnected system, where multiple detectors sound simultaneously if one is triggered. This is particularly beneficial in larger homes or for families, ensuring that everyone is alerted promptly to any danger.

The battery-operated design means there’s no need for complicated wiring, making installation simpler. With a lifespan of 10 years and only one battery replacement needed, maintenance is minimal. The app integration allows for real-time alerts and notifications, which is great for tech-savvy users who want to stay informed, even when they’re away from home.

However, there are some drawbacks to consider. Since it’s not hardwired, its reliance on battery power could be a concern for some users, especially if the batteries are not replaced on schedule. While the app features are convenient, they may be overwhelming for those who prefer a simpler, more traditional approach to smoke detectors. Additionally, the optional Protect+ Premium subscription for fast fire dispatch adds an extra cost, which might not appeal to everyone.

The X-Sense Smart Smoke Detector and Carbon Monoxide Detector combo is designed to keep your home safe by combining two key sensors: a photoelectric sensor for smoke and an electrochemical sensor for carbon monoxide. This 3-pack runs on replaceable lithium CR123A batteries, which means no complicated wiring—making installation straightforward with the included screws. It connects to your home Wi-Fi but only on the 2.4 GHz band, so if you have a 5 GHz network, it won’t work. Each detector connects individually to the X-Sense Home Security app, which lets you get real-time alerts and share access with up to 12 people, making it ideal for families or roommates who want to stay informed about home safety.

The alarms are audible and will notify you immediately through your phone if smoke or CO is detected, or if there’s a fault or low battery. A notable feature is the optional Protect+ subscription for 24/7 professional monitoring, including rapid fire dispatch within 3 seconds after an emergency is confirmed, providing extra peace of mind if you’re often away from home. However, these detectors don’t communicate with each other, meaning each device operates independently without syncing or coordinating alerts. There is also no integration with popular smart home systems like Alexa or Google Home, which might limit automated routines or voice alerts.

The build quality uses heat-resistant plastic, and the units are compact and lightweight. With a strong customer rating of 4.5 stars and a 5-year warranty, this product is a reliable choice for people wanting a battery-powered, Wi-Fi-connected detector combo. It suits homeowners or renters who prefer a simple, app-based notification system without complex smart home setups. If you want detectors that work closely together or integrate fully with other smart devices, this product might feel limited.

The X-Sense Wireless Interconnected Smoke Detector is a solid choice for families looking to enhance their home safety with a smart smoke detection system. One of the standout features is its ability to interconnect wirelessly with up to 24 other alarms, ensuring that if one sounds, all will alert simultaneously, providing a comprehensive safety net throughout the home. This feature is especially beneficial for larger spaces or multi-story residences, where hearing a distant alarm could be difficult.

Installation is a breeze, as these battery-powered detectors can be mounted on walls or ceilings without the need for hardwiring. The mini design makes them unobtrusive, blending well with most home decors. Additionally, the included 5-year battery life means less frequent maintenance, and users will appreciate the low-battery warning that alerts them when it’s time for a replacement.

It’s important to note that the XS01-WR does not offer Wi-Fi connectivity, which might limit its appeal for those wanting a fully smart home integration with remote monitoring capabilities. If Wi-Fi is a requirement, users should consider the XS01-WX model instead. Also, while the photoelectric sensor is effective in detecting smoldering fires, some users prefer dual-sensor models (which include ionization sensors) for comprehensive fire threat coverage.
