10 Best Smart Smoke Alarm 2025 in the United States

The X-Sense Smoke and Carbon Monoxide Detector Combo is a strong contender if you're looking for an all-in-one safety solution for your home. One of its standout features is the wireless interconnection capability. This means if one alarm detects smoke or carbon monoxide, all connected alarms will go off, ensuring that you and your family are alerted no matter where you are in the house. This setup supports up to 24 interconnected devices, which is excellent for full-home protection.

The product also boasts a 10-year sealed lithium battery, so there's no need to worry about changing batteries frequently, and it ensures the device is always operational. It combines smoke and carbon monoxide detection, offering dual protection in a single unit, which is highly convenient and space-saving. Made from heat-resistant and high-temperature resistant PC material, it is durable and reliable.

However, it's important to note that while it supports wireless interconnection, it does not have Wi-Fi capabilities. This means you won't receive alerts on your smartphone if an alarm is triggered, which is a downside for those looking for smart home integration. Installation is straightforward, thanks to the wireless design, but keep in mind that the unit is powered by 12 included lithium metal batteries, so you should ensure they're all properly installed and maintained. For those looking for a reliable, interconnected smoke and carbon monoxide detector without the need for smart home compatibility, the X-Sense Combo provides robust protection with minimal upkeep.

The X-Sense Wireless Interconnected Combination Smoke and Carbon Monoxide Detector is a solid option for those looking to enhance their home safety. One of its standout features is the wireless interconnectivity, allowing all alarms in the system to sound an alarm if any unit detects smoke or carbon monoxide. This helps ensure that alerts can be heard throughout your home, which is crucial for safety.

The product boasts both photoelectric and electrochemical sensors, which provide reliable detection of both smoke and dangerous CO levels. Its informative LCD display is a significant advantage, giving real-time CO level readings and battery status, adding to user convenience.

With a built-in 10-year battery, there's no need for constant battery replacements, which saves time and reduces hassle. The 6-pack option is a great value for those looking to protect multiple rooms in a house, covering an area of 215-430 sq. ft. per unit. However, the unit lacks Wi-Fi capability, which means it won't connect to smart home systems or send alerts to your phone. If Wi-Fi connectivity is a priority for you, you would need to look at their SC07-WX model. Additionally, while the installation is straightforward with a screw-in method, some users may still find it challenging if they are not handy.

The X-Sense Smoke Detector SD20-W Pack of 6 offers a reliable solution for home safety with several notable strengths. One of its key advantages is the 10-year lifespan backed by a built-in lithium battery, which means you won't need to worry about battery replacements for a decade. The wireless connectivity feature allows up to 24 devices to be interconnected, providing a comprehensive safety network across your home. This also includes compatibility with carbon monoxide alarms and combination alarms, enhancing protection.

The photoelectric sensor type ensures accurate smoke detection, and the loud 85 dB alarm is designed to wake even deep sleepers in case of an emergency. Additionally, the ABS flame-retardant material enhances durability and safety. Installation is straightforward with the included screws and anchor plugs, and the pre-connected units make setup even easier.

There are a few drawbacks to consider. While the battery's long life is a plus, it is non-replaceable, meaning the entire unit will need to be replaced after 10 years. Additionally, the alarm, while loud, might not be sufficient for larger homes or for individuals with hearing impairments. The coverage area per unit is between 215-430 sq. ft., which may require multiple units for larger spaces.
