Aqara Smart Smoke Detector vs X-Sense Wi-Fi Carbon Monoxide Alarm

The X-Sense Wi-Fi Carbon Monoxide Alarm wins overall on price, owner rating, a 5-year warranty and its live-reading LCD screen. However, the two sense different hazards, so the Aqara Smart Smoke Detector remains the better choice specifically for smoke detection and smart-home integration.

The biggest difference is what they detect. The Aqara Smart Smoke Detector senses smoke only, while the X-Sense Wi-Fi Carbon Monoxide Alarm senses carbon monoxide only. They protect against different dangers, so many households would use one of each rather than choosing between them.

No. The Aqara Smart Smoke Detector covers smoke and fire but not carbon monoxide, and the X-Sense Wi-Fi Carbon Monoxide Alarm covers CO but has no smoke sensor or fire alerts. For full protection you would need a smoke alarm and a CO alarm, or a single combined smoke-and-CO unit.

Only the Aqara Smart Smoke Detector has smart-home integrations, supporting Apple HomeKit, Home Assistant, IFTTT and Matter over Zigbee. The X-Sense Wi-Fi Carbon Monoxide Alarm connects only to its own app over Wi-Fi with no Alexa, Google Home, HomeKit or Matter support.

Buy the X-Sense Wi-Fi Carbon Monoxide Alarm if you need dedicated carbon monoxide detection for a home with gas appliances, a boiler or a wood stove, and you want a well-rated, affordable unit with a live-reading LCD, phone alerts and a 5-year warranty.

Buy the Aqara Smart Smoke Detector if you want smoke detection integrated into a Zigbee, Apple HomeKit, Home Assistant or Matter smart home with automation triggers, keeping in mind it does not detect carbon monoxide.
