I have just setup this air quality tester and the good news is that the menu can be changed to English language. Also this device is accessible from mi home app if you change your location to mainland China in the settings while keeping the language as English. I am satisfied by the build quality and the accuracy of this device since it is consistent with the PM data being provided by my air purifier and another indoor temperature and humidity meter that I have.

This is usefull measurement for home using. I wanted to see co2 level and history. The sensors are only low cost but longlive. It is good do restart every week, becose co2 was to high in the outdoor. After power off it is ok. With app is possible to read numbers and history also from internet. You should set location china in app mi home for working.
