bought some months ago cheap smart and humidity meter it worked fine till recently
today it stopped working showed all digits
I disassembled this thing and found to my surprise CB3S board
with following command:
python3 hid_download_py/uartprogram firmwares/OpenBK7231N_QIO_1.18.177.bin --unprotect -d /dev/ttyUSB0 -w --startaddr 0x0 it worked fine
after that I got the usual OPENBEKEN screen
now the question will be how to address display and all the previous functions
kindly ask you whether anyone has already got this device and also I am curious whether I configure the display and all functionalities
hoping for some info
AI: could you please tell the exact brand and model of your smart humidity meter, maybe a link to the product or a photo of the label?
its cheap temu with no brand on it all other data are on photo on the pc the only number I could see apart from CB3S was AS90_1622051 OA the chip driving the display is GNV179S
AI: do you know what type of display is inside (like segment, I2C, SPI, or chip model), or can you share a photo of the display and how it connects to the CB3S board?
see in the enclosure
