Carbon monoxide detectors homekit in comparison

Accurate and Reliable - This CO alarm is equipped with a 10-year sensor that can give a high and stable performance of accurate CO detection and ensures few false alarm.

Advanced electrochemical sensor When exposed to carbon monoxide, it immediately generates current, which means it responds faster and more accurately than traditional carbon monoxide detectors, and is not easily affected by other gases. Please note that it is normal for the product to display a reading of 000PPM when there is no carbon monoxide gas in the air.

Audio-visual Alarm Provides an audio-visual alarm function. In default mode, when the carbon monoxide concentration reaches and exceeds 50ppm, the screen's yellow or red indicator bars will flash, accompanied by a high-decibel alarm. As the carbon monoxide concentration increases, the alarm frequency accelerates, enabling you to promptly detect danger and protect yourself

Warning of carbon monoxide poisoning due to incomplete combustion (fireplace gas boiler)

Informative LCD shows real-time CO concentrations and battery power to monitor for CO leaks and battery level; to save power, it will activate only when the device is tested or the ppm has reached the alarm level for a certain period

IP44 grade

Real-Time LCD Display The large, easy-to-read LCD screen provides consistent and clear readings of CO levels, even at zero. A built-in backlight ensures clear visibility in low-light conditions, enabling 24 7 monitoring without interruption.

Multi-Protocol Hub with Matter Bridge The M3 is a versatile hub supporting Aqara Zigbee (**Not third-party zigbee device) and Thread devices. It integrates third-party devices into the Aqara Home app (currently limited to select device types, will be expanded over time). Supports advanced Matter bridge functionality, enabling Aqara-exclusive scenes and signals to sync with Matter ecosystems such as home assistant for seamless integration. Supports up to 127 Aqara Zigbee devices and 127 Thread devices (Repeaters are needed).
