Full Smart Smoke & CO Detectors comparison in 2026

Two Zigbee smoke sensors, two different priorities: the Heiman HS1SA Series Smoke Alarm is the better value, cheaper and a little better reviewed for the same core job.

Both need a Zigbee hub, both detect smoke only, both have a siren and a light, both are rated for 10 years on their battery and both work with SmartThings and Home Assistant and support automations. The Aqara Smart Smoke Detector wins on platforms: it also works with Apple HomeKit and Matter, and with Alexa and Google Home through an Aqara hub, which the Heiman cannot match. The Heiman is also the smaller of the two at 60 x 60 mm. Choose the Heiman HS1SA Series Smoke Alarm for a discreet, low-cost Zigbee smoke sensor on SmartThings or Home Assistant, and the Aqara Smart Smoke Detector if your home runs on Apple Home, Matter or an Aqara hub.

What the differences mean

Apple Home, Matter and voice assistants

The Aqara Smart Smoke Detector works with Apple HomeKit and Matter, and with Alexa and Google Home through an Aqara hub. The Heiman HS1SA Series Smoke Alarm has no HomeKit, Matter or Alexa support, and its Google Home status is not documented.

Shared ground

Both use Zigbee and need a hub, both work with SmartThings and Home Assistant and support automations, and both detect smoke only. If your hub is SmartThings or Home Assistant, either will do the same job.

Size

The Heiman HS1SA Series Smoke Alarm is a 60 x 60 mm block, the Aqara Smart Smoke Detector a round unit 104.6 mm across. The Heiman is the easier one to hide.

Warranty

Aqara documents a 1-year warranty. Heiman publishes no warranty term for the HS1SA, so check what the seller offers.

Which one to buy if

What owners say

Owners of both agree on two things: the siren is loud, and the battery does not always live up to its decade rating, so the difference is not there. Aqara Smart Smoke Detector owners are smart home builders who talk about pairing it with Home Assistant, HomeKit or an Aqara hub in minutes, linking several units so one alarm sets off all of them, and triggering lights on smoke; a few also mention weak Zigbee range. Heiman HS1SA Series Smoke Alarm owners talk less about automations and more about the hardware: how loud it is for such a small unit, its discreet look and mounting it with an adhesive pad in bedrooms, hallways and campervans. Their extra complaint is that the exact replacement cell can be hard to find, and a few saw the adhesive mount loosen.

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.

Frequently Asked Questions

Which is better: Aqara Smart Smoke Detector or Heiman HS1SA Series Smoke Alarm?

The Heiman HS1SA Series Smoke Alarm is the better value for a Zigbee smoke sensor on SmartThings or Home Assistant. The Aqara Smart Smoke Detector is the better pick when you need Apple HomeKit, Matter, or Alexa and Google Home through an Aqara hub.

Do both need a Zigbee hub?

Yes. The Aqara Smart Smoke Detector and the Heiman HS1SA Series Smoke Alarm both use Zigbee and have no Wi-Fi, so phone alerts and automations depend on a hub such as an Aqara hub, SmartThings or Home Assistant.

Which one works with Apple HomeKit?

Only the Aqara Smart Smoke Detector, which supports Apple HomeKit and Matter. The Heiman HS1SA Series Smoke Alarm works with SmartThings and Home Assistant but not HomeKit.

Do they detect carbon monoxide?

No. The Aqara Smart Smoke Detector and the Heiman HS1SA Series Smoke Alarm both detect smoke only, so a home with gas appliances still needs a CO alarm.

How long do their batteries last?

Both are rated for 10 years, but owners of the Aqara Smart Smoke Detector and the Heiman HS1SA Series Smoke Alarm alike report cells running down sooner, so keep an eye on battery level through your hub.
