X-Sense Wi-Fi Carbon Monoxide Alarm vs X-Sense Wi-Fi Smoke Alarm

It depends on the hazard, but the X-Sense Wi-Fi Carbon Monoxide Alarm rates slightly ahead and adds an LCD readout. It detects carbon monoxide, while the X-Sense Wi-Fi Smoke Alarm detects smoke, so many homes run one of each rather than picking just one.

The hazard they cover. The X-Sense Wi-Fi Carbon Monoxide Alarm senses carbon monoxide and shows live levels on an LCD, while the X-Sense Wi-Fi Smoke Alarm senses smoke and has no screen. One is not a replacement for the other.

Yes. Both connect over 2.4GHz WiFi to the X-Sense app, use a replaceable CR123A battery and carry a 5-year warranty, and neither integrates with Google Home, Alexa, HomeKit or Matter.

For complete protection, generally yes, because the X-Sense Wi-Fi Carbon Monoxide Alarm covers carbon monoxide and the X-Sense Wi-Fi Smoke Alarm covers smoke and fire. Alternatively, a combined smoke-and-CO detector handles both hazards in one unit.

Buy the X-Sense Wi-Fi Carbon Monoxide Alarm if your home has gas appliances, a boiler or a wood stove and you want a standalone CO detector with a live LCD reading and phone alerts.

Buy the X-Sense Wi-Fi Smoke Alarm if you need simple, connected smoke detection with WiFi phone alerts and a long battery rating, and you are covering carbon monoxide separately or not at all.
