Xiaomi Mijia ClearGrass (Qingping)


I’ve been trying to add this device:

Which is supported by the Mi Home app and looks very similar to the LCD model, but had no luck.
I was able to retrieve a few values from Bluetility (Mac) using its MAC Address such as:

Manufacturer Name: Qingping Technology (Beijing) Co., Ltd.
Model Number: CGG1
Hardware Revision: 0001
Firmware Version: 1.1.2_0011

But had no luck retrieving the Temperature, Humidity and Battery readings with gatttool nor with mitemp_bt platform.

Does anyone had luck getting those to report or can give me a hint?
Thank you in advance!


the guy said it works with HA without problem

Thank you for the reply but that is not the same unit. That unit has WiFi so you can retrieve information from its IP address.
My unit is Bluetooth only so I cannot GET or POST to it, only subscribe to its channels which brings data that looks encrypted. :pensive:

I raised a question over on the ESPHome github about whether it is supported by ESPhome.The LCD version is supported, but no-one knew if the epaper version also was.
Given both seem to be manufactured by the same company (cleargrass) you could make an assumption… :slight_smile:

Thank you @hijinx! That’s an awesome idea!
I do not have any ESP devices here at the moment to test, but I got this tutorial that might be useful:


I also do not have any Android device in order to test it, but I am asking my friends and trying to get one. Perhaps it can work that way.


let me know how this goes as I just got one of these and would like to get it working in HA
