10 Best Wifi Smoke Alarms 2025 in the United States

The X-Sense Wireless Interconnected Smoke Detector Fire Alarm (XS01-WR Link+) is a robust choice for home safety, especially if you need comprehensive coverage across multiple areas. One of its standout features is the interconnection capability, allowing up to 24 detectors to link together. This means if one alarm goes off, all of them do, making sure the alert is heard throughout the house. It also has an intelligent locating function to quickly find the source of the fire, adding valuable seconds for safety measures.

The transmission range is impressive at over 820 feet, providing reliable performance even in large homes with multiple floors, basements, or garages. The installation is straightforward, as it doesn't require hardwiring and can be mounted easily with the provided screws and anchors. The model comes with 12 smoke alarms and includes batteries that last for 5 years, and it has a low-battery warning to ensure timely replacement.

This model does not have Wi-Fi capability, so it won’t connect to your smartphone or smart home system. If you need Wi-Fi integration, you’ll need to look at the XS01-WX model instead. The alarm is designed to be unobtrusive with its compact size, and it includes a test/silence button for easy operation. The main drawback is the lack of Wi-Fi connectivity, which might be a dealbreaker for those seeking smart home integration. Those who prioritize interconnected alarms and wide coverage without the need for smartphone notifications will find this model to be a reliable pick.

The X-Sense Wireless Interconnected Combination Smoke and Carbon Monoxide Detector is a solid choice for those seeking comprehensive safety for their homes. One of its major strengths is the interconnected design; when one unit detects smoke or carbon monoxide, all alarms in the network will sound, ensuring you’re alerted no matter where you are in the house. This feature is particularly useful for larger living spaces and enhances safety by providing early warnings.

The device combines two essential safety features: a photoelectric smoke sensor that is effective in detecting smoldering fires and an electrochemical sensor for carbon monoxide. This dual protection is a significant advantage, giving you peace of mind knowing that you’re covered against both threats. Another noteworthy benefit is the built-in 10-year battery life, which eliminates the hassle of frequent battery replacements. The informative LCD display showing CO levels and battery status adds an extra layer of convenience, allowing you to monitor conditions at a glance.

The installation process is straightforward, requiring just a screw-in method, making it accessible for most users. The 6-pack option is also a cost-effective way to cover multiple rooms, but ensure that your coverage needs are met, as each unit covers around 215-430 sq. ft. The X-Sense detector is an excellent choice for those who prioritize a reliable and interconnected smoke and CO alarm.
