Delivered to the Ring app, so no midnight chirping
IEEE 802.11b/g/n
Wire-free interconnect so all Kidde alarms in the home sound together
The large LCD indicates how much carbon monoxide the alarm is detecting, ranging from 30 to 999 ppm.
Enhanced sensing reduces cooking nuisance alarms versus earlier Kidde generations
Alexa's smart home API has no smoke or CO alarm type: the only supported route is the Matter Smoke CO Alarm device type, which this alarm does not speak
X-Sense confirms its smoke and CO alarms do not work with Alexa: only the AS05 and AS08 security kits are Alexa compatible, and Alexa's API has no smoke or CO alarm type anyway
Community HACS integration for the hubless Wi-Fi Kidde and Ring smart smoke and CO detectors
Community X-Sense integration for Home Assistant (HACS), which lists this model and reads it from the X-Sense cloud account
2 AA alkaline batteries included
Electrochemical, with low-level CO mobile alerts
Photoelectric, over 25% faster than a leading competitor in Kidde testing

The table matches specifications by section and field. It preserves notes, separates missing data from explicit “No” values, and keeps qualifications attached to their values. No overall winner is assigned from feature counts.
