Xiaomi Mijia Honeywell Gas Alarm, Methane Detector

Category Tags ,

The Xiaomi Mijia Honeywell Gas Alarm completes the family of home security sensors. We already knew the smoke detector, it is able to detect the presence of natural gas (methane) in the atmosphere. It can for example be installed in a kitchen equipped with a stove or a boiler fueled by natural gas.

Be careful, just like the Xiaomi Mijia Honeywell smoke detector, this detector is not CE and FCC certified. It is reserved for the Chinese domestic market. It is possible to buy and use it outside China only if it complements a certified sensor that already equips your home. Attention, this sensor detects only the presence of methane in the air. It does not work with other gases (propane, butane ..)


The Zigbee2mqtt project now allows Xiaomi accessories to be integrated into a home automation server (Domoticz, Jeedom, Home Assistant, Open Hab …) without having to buy the official gateway. It’s more economical and you have full control over the data collected by Xiaomi sensors. Here are several tutorials to start

    If you prefer the official solution, you will need to buy the Xiaomi Smart Home gateway and the Mi Home app for iOS and Android is required. It is also possible to use the motion detector on most open source home automation software (Jeedom using a plugin, Domoticz or Home Assistant). To learn more, you can read this tutorial of unpacking the kit Xiaomi Smart Home 6 in 1 and this one for an example of integration in Home Assistant.

    Xiaomi Mi Home gateway 5 in 1 pack

    For a first installation, it is more interesting to buy the gateway Xiaomi Mi Home in a pack. The 5 in 1 pack is more interesting outside China because it does not integrate the connected socket.
