10 Best Wifi Smoke Alarms 2025 in the United States

The X-Sense Combination Smoke and Carbon Monoxide Detector (Model XP0A-MR31) stands out for its comprehensive protection and modern features. With both smoke and CO sensors, it offers 2-in-1 detection, simplifying installation and saving space. The voice location feature is particularly useful, providing clear, spoken alerts that specify the detected threat and its location, which can expedite evacuation and response times.

The device can be interconnected via an app, sending instant alerts to your phone and up to 12 family members, ensuring everyone stays informed. An ultra-slim design allows it to blend seamlessly into your home décor, and it’s made from heat-resistant PC plastic, adding to its durability. The replaceable CR123A battery promises up to 5 years of use, with a sensor lifespan of 10 years, contributing to long-term reliability.

The optional Protect+ Premium subscription provides 24/7 professional monitoring, potentially dispatching emergency services within 3 seconds of alarm verification. However, this service incurs an additional cost. Installation is user-friendly, with spoken instructions to guide you through the setup and maintenance processes, such as pairing over Wi-Fi and testing the alarms. This model is a solid choice for those seeking a high-tech, reliable detection system, particularly in tech-savvy households looking for modern conveniences and proactive safety features.

The X-Sense Smart Smoke and Carbon Monoxide Detector combo offers a solid safety solution with combined photoelectric smoke and electrochemical CO sensors, providing reliable multi-hazard detection. Its replaceable lithium batteries are included and promise long-lasting use, which is convenient since it’s not hardwired. This 10-pack is great if you want to cover multiple rooms or a larger home with consistent alarms.

The Wi-Fi connectivity works on 2.4 GHz networks and allows real-time alerts on your phone through the X-Sense Home Security app, so you can monitor your home even when away. You can also share device access with up to 12 family members or friends, adding a layer of shared safety awareness. The alarms don’t communicate with each other directly, so each unit must be managed individually via the app, which might be less seamless than interconnected systems. It doesn’t support 5 GHz Wi-Fi or integration with other smart home platforms, which may limit how well it fits into a wider smart home setup.

Installation is straightforward since it’s battery-powered, avoiding complicated wiring, and maintenance involves replacing batteries supplied in the pack. For those seeking professional emergency monitoring, there’s an optional subscription that provides rapid response within seconds after an alarm triggers, which can be reassuring but adds ongoing cost. This product suits users wanting dependable, easy-to-install multi-room coverage with remote alerts but who don’t require full smart home integration or interconnected alarms.

The X-Sense Smart Smoke Detectors with the SBS50 base station offer reliable smoke detection using photoelectric sensors, which are effective at spotting slow, smoldering fires. The system connects through 2.4 GHz Wi-Fi only, which is common but means it won’t work on newer 5 GHz networks. It links to the included base station that supports up to 50 devices, allowing you to build a comprehensive home safety system including smoke, carbon monoxide, and water leak sensors.

Alerts are sent instantly to your phone via the X-Sense Home Security app, so you’ll know right away if there’s danger or if batteries run low. The alarms themselves are loud and interconnected wirelessly, so every alarm sounds when one detects smoke, helping alert everyone at home. Installation is fairly straightforward with included screws and anchors, and the app even lets you test alarms remotely, saving you from climbing up to press a button. Battery life is solid with replaceable CR123A lithium batteries included, and the system has a 5-year warranty plus lifetime support.

A point to consider is the need for the base station to connect the alarms to Wi-Fi, so direct Wi-Fi connection isn’t available. Also, to get professional 24/7 monitoring with fast fire dispatch, you’ll need to pay for an optional subscription. This set is suitable for homeowners wanting a smart, interconnected smoke alarm system with good app control and expandability, especially if your home Wi-Fi runs on 2.4 GHz and you’re comfortable managing a base station.
