Frequently Asked Questions
Which is better overall, the Kidde Smart Smoke & CO Detector with Ring or the Aqara Smart Smoke Detector?
Kidde Smart Smoke & CO Detector with Ring, because it detects carbon monoxide as well as smoke, needs no hub, sends free alerts through the Ring app and filters cooking steam. Aqara Smart Smoke Detector wins on price and on integrations, supporting Apple HomeKit, Home Assistant, IFTTT and Matter.
Does the Aqara Smart Smoke Detector detect carbon monoxide?
No. Aqara Smart Smoke Detector has a smoke sensor only, with no CO sensor and no CO alerts. Kidde Smart Smoke & CO Detector with Ring combines photoelectric smoke detection with an electrochemical CO sensor and sends low-level CO alerts to your phone before the audible alarm triggers.
Does either one need a hub?
Aqara Smart Smoke Detector does: it is a Zigbee device and needs a compatible hub for alerts and automations. Kidde Smart Smoke & CO Detector with Ring joins 2.4 GHz Wi-Fi directly and also carries a wire-free interconnect so all Kidde alarms in the home sound together.
Which fits better into a smart home?
Aqara Smart Smoke Detector, which works with Apple HomeKit, Home Assistant, IFTTT and Matter, so smoke can trigger lights, locks or notifications. Kidde Smart Smoke & CO Detector with Ring works with Alexa and the Ring app, but has no Google Home, HomeKit, SmartThings or Matter support.
How do they handle false alarms and batteries?
Kidde Smart Smoke & CO Detector with Ring uses enhanced sensing to reduce cooking nuisance alarms and sends low-battery warnings to the Ring app instead of chirping at night, on two included AA batteries. Aqara Smart Smoke Detector runs a CR17450 rated for ten years, though owners report shorter real-world life.
Who should buy the Aqara Smart Smoke Detector?
Owners of an existing Zigbee or Aqara hub who want smoke detection woven into automations, and Apple Home or Matter households, at a lower price with an 85 dB siren. If you want carbon monoxide coverage and hub-free phone alerts, Kidde Smart Smoke & CO Detector with Ring is the better device.
