Data from the official Aqara and X-Sense sites.
2026 verdict
For whole-home coverage, the X-Sense SC07-MR Smart Smoke & CO Alarm is the better buy: it watches for smoke and carbon monoxide at once, links to other X-Sense alarms over RF without a hub, and carries a five-year battery and warranty.
The Aqara Smart Smoke Detector answers with deeper smart home integration, working with Home Assistant, SmartThings, Apple HomeKit and Matter through a hub, plus a longer ten-year battery rating and a built-in status light. The catch is that the Aqara needs a Zigbee hub to do anything smart and only senses smoke, while the X-Sense is a self-contained life-safety unit whose app features need a base station. Choose the X-Sense SC07-MR Smart Smoke & CO Alarm for protection first, and the Aqara Smart Smoke Detector if you already run a Zigbee hub and want smoke woven into automations.

What the differences mean
What it detects
The X-Sense SC07-MR Smart Smoke & CO Alarm senses both smoke and carbon monoxide with a photoelectric and an electrochemical sensor, covering the two hazards that need a detector. The Aqara Smart Smoke Detector senses smoke only, so a separate CO alarm is still needed where gas appliances or a boiler are present.
Home for the hub
The Aqara Smart Smoke Detector is Zigbee and requires a compatible hub, such as the Aqara Hub M3, before it can send app alerts or take part in any automation. The X-Sense SC07-MR Smart Smoke & CO Alarm works as a standalone alarm with no hub; only the Wi-Fi and app side needs an X-Sense base station, sold separately.
Interconnection
The X-Sense SC07-MR Smart Smoke & CO Alarm links to other X-Sense Link+ and Link+ Pro alarms over RF with no base station, so one detecting smoke sounds the whole set. The Aqara Smart Smoke Detector has no such direct link and only 'sounds them all' through the automations your hub can build.
Battery and warranty
The Aqara Smart Smoke Detector is rated for ten years on its CR17450 cell, against five on the X-Sense SC07-MR Smart Smoke & CO Alarm's CR123A, but owners report the Aqara draining much faster than its rating. The X-Sense backs its unit with a five-year warranty next to the Aqara's one year.
Smart home reach
The Aqara Smart Smoke Detector is the more connected device once it has a hub, reaching Home Assistant, SmartThings, Apple HomeKit, Google Home, Alexa and Matter. The X-Sense SC07-MR Smart Smoke & CO Alarm integrates with Home Assistant only, and has no Alexa, Google Home, HomeKit, SmartThings or Matter support.
On-device readout
The X-Sense SC07-MR Smart Smoke & CO Alarm has an LCD that shows the CO level and alarm status on the unit itself, while the Aqara Smart Smoke Detector relies on its app and a status LED with no screen.
Which one to buy if
- the home has a gas boiler, stove or attached garage
The X-Sense SC07-MR Smart Smoke & CO Alarm covers smoke and carbon monoxide in one ceiling unit, where the Aqara is smoke only.
- you do not want to buy or run a hub
The X-Sense SC07-MR Smart Smoke & CO Alarm stands alone and interconnects over RF, while the Aqara Smart Smoke Detector is a brick without a Zigbee hub.
- your home runs on Home Assistant, HomeKit or Matter
The Aqara Smart Smoke Detector reaches all of those through a hub and can fire lights, locks and notifications from a smoke event.
- you are fitting an entire house and want the alarms to sound together
Several X-Sense SC07-MR Smart Smoke & CO Alarms link over RF without extra hardware, which the Aqara cannot do on its own.
- you want the longest possible gap between battery changes
The Aqara Smart Smoke Detector is rated for ten years against five, though owners find the real figure shorter and worth monitoring.

What owners say
Aqara Smart Smoke Detector owners are mostly smart home hobbyists who already run a Zigbee network, and they describe pairing it to Home Assistant, Apple HomeKit or an Aqara hub in minutes and then building automations from there. The 85 dB siren is called loud enough to be unmissable, and several owners link several units so that one smoke trigger sounds them all and can switch on emergency lighting. Their recurring complaint is battery life: the CR17450 cell is rated for ten years, but a number of buyers report the percentage reading low out of the box and draining far faster under Zigbee2MQTT or ZHA, so it pays to watch it through the hub. A smaller group found the Zigbee range weak enough that the hub had to sit close by.
Frequently Asked Questions
Which is better, the Aqara Smart Smoke Detector or the X-Sense SC07-MR Smart Smoke & CO Alarm?
As a life-safety device, the X-Sense SC07-MR Smart Smoke & CO Alarm is the stronger pick because it detects both smoke and carbon monoxide, interconnects with other X-Sense alarms without a hub, and carries a five-year warranty. The Aqara Smart Smoke Detector is the better smart home device, reaching Home Assistant, HomeKit, Matter and more through a hub, but it senses smoke only and needs that hub to work at all.
Does the Aqara Smart Smoke Detector detect carbon monoxide?
No. It is a smoke-only detector, with no CO sensor and no CO alerts, so a home with gas appliances still needs a separate carbon monoxide alarm. The X-Sense SC07-MR Smart Smoke & CO Alarm has both a photoelectric smoke sensor and an electrochemical CO sensor in the same unit.
Do these alarms need a hub or base station?
The Aqara Smart Smoke Detector needs a Zigbee hub, such as the Aqara Hub M3, to join a smart home and send alerts. The X-Sense SC07-MR Smart Smoke & CO Alarm works on its own and interconnects with other X-Sense alarms over RF without any base station; only its Wi-Fi and app features require an X-Sense base station.
Which one works with more smart home platforms?
The Aqara Smart Smoke Detector works with Home Assistant and SmartThings directly and reaches Apple HomeKit, Google Home, Alexa and Matter through a Matter capable hub. The X-Sense SC07-MR Smart Smoke & CO Alarm supports Home Assistant only and has no Alexa, Google Home, HomeKit, SmartThings or Matter support.
How long do the batteries last?
The X-Sense SC07-MR Smart Smoke & CO Alarm is rated for five years on CR123A batteries, matched by its five-year warranty. The Aqara Smart Smoke Detector is rated for ten years on a CR17450 cell, but several owners report it draining much faster than that in practice, so it is worth checking the level in your hub.
Who should buy the X-Sense SC07-MR Smart Smoke & CO Alarm?
Anyone fitting smoke and carbon monoxide protection who wants an alarm to work without a hub, and who plans to install several so they interconnect over RF. Buyers who want the alarm tied into a Home Assistant or HomeKit automation system, and who are happy to maintain a Zigbee hub, are better served by the Aqara Smart Smoke Detector.
