Xiaomi Mijia Honeywell Smart Gas Alarm Detector CH4 Gas Monitoring Ceiling and Wall Mounted Mihome APP Remote Control

Xiaomi Mijia Honeywell Gas Alarm is a smart sensor. It is designed to report environmental or occupancy events for monitoring and automation. Protocol, gateway and app requirements are important because they determine which automations are available.

The product is compatible with Xiaomi Home / Mi Home for the exact version described here. The Xiaomi Mijia/Honeywell gas-alarm listing explicitly states Mi Home app remote monitoring.

Target gas is CH4 / natural gas; Mounting is Ceiling or wall; Control is Mi Home app remote monitoring.

For reliable automations, position the sensor according to its documented range and avoid obstacles or environmental conditions that can distort readings. Battery-powered sensors should also be checked periodically even when the app reports battery status. A compatible gateway is required whenever the device does not communicate directly over Wi-Fi.

For automations, match the sensor to the documented protocol and gateway. Region-specific Mi Home devices may require the Mainland China region, while Smart Life, Aqara Home or other ecosystems are not interchangeable with Mi Home.
