It pairs a photoelectric smoke sensor with an electrochemical CO sensor, shows readings on an LCD, connects straight to 2.4 GHz Wi-Fi and carries a 5-year warranty against 1 year for the Aqara. The Aqara Smart Smoke Detector is the smart home specialist: through a Zigbee hub it works with Apple HomeKit, Matter, SmartThings and Home Assistant, reaches Alexa and Google Home through an Aqara hub, and can trigger automations, while the X-Sense lists only Home Assistant. It is also the smaller of the two on the ceiling. Choose the X-Sense WiFi Smoke & CO Detector for one device that covers both hazards without a hub, and the Aqara Smart Smoke Detector when smoke alerts need to drive a HomeKit or Home Assistant setup.

What the differences mean

Carbon monoxide

The X-Sense WiFi Smoke & CO Detector detects carbon monoxide as well as smoke, so one unit covers both hazards near a boiler or fireplace. The Aqara Smart Smoke Detector detects smoke only and needs a separate CO alarm beside it.

Hub or Wi-Fi

The Aqara Smart Smoke Detector is Zigbee only, so phone alerts depend on a hub. The X-Sense WiFi Smoke & CO Detector joins 2.4 GHz Wi-Fi directly and alerts your phone through its app.

Smart home reach

The Aqara Smart Smoke Detector works with Apple HomeKit, Matter, SmartThings and Home Assistant, and with Alexa and Google Home through an Aqara hub, and it supports automations. The X-Sense WiFi Smoke & CO Detector lists Home Assistant only and runs no automations.

Size and screen

The X-Sense WiFi Smoke & CO Detector measures 144 x 144 mm and carries an LCD, a noticeably bigger disc on the ceiling. The Aqara Smart Smoke Detector is a smaller round unit, 104.6 mm across, with no display.

Warranty

X-Sense backs the X-Sense WiFi Smoke & CO Detector for 5 years, while Aqara covers its smoke detector for 1 year, a real gap for a device meant to stay on the ceiling for years.

Which one to buy if

What owners say

Owners of both praise a loud siren and an easy install, so neither pulls ahead there. Aqara Smart Smoke Detector owners are smart home builders: they describe pairing it with Home Assistant or an Aqara hub in minutes and using a smoke alert to turn on lights or set off linked alarms. They also report the battery draining far faster than the rated decade, and a few had trouble with Zigbee range. X-Sense WiFi Smoke & CO Detector owners bought it for coverage, often near pellet stoves, fireplaces or new heating systems, and single out having both sensors in one unit, the easy-to-read LCD and quick warranty replacements. Their complaints are practical: it is larger than a typical smoke alarm and the bracket is fiddly to line up level.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
