    Yes yes, sorry, permission granted! And it seems it worked that time! All builds are successfull. https://github.com/openshwprojects/OpenBK7231T_App/pull/1333

    @p.kaczmarek2 Seriously, wouldn't it have been easier for you to give me a file with the TM 1637 driver included? I don't quite understand what I'm clicking on the site to create the firmware and I still have to wait for your approval. It's long and complicated. If anything, I'm sorry.

    Somehow I connected it, there is a shift of one sign. How to fix it?

    When I enter the command TMGN_print 0 0 1234 On the display I see what is in the photo below.

    If digits order is not standard, then you need to try one of many TMGN_Map combinations.
    Start with:
    Code: text Expand Select all Copy to clipboard
    
TMGN_Map 01234567
TMGN_print 0 0 1234 

    check result, of course do print on screen after doing map command.
    If still wrong, try:
    Code: text Expand Select all Copy to clipboard
    
TMGN_Map 32104567
TMGN_print 0 0 1234 

    etc, etc.
    Here are docs:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/commands.md

    This is because the order of digits is not standarized in those modules.

    @p.kaczmarek2 I don't know what the problem is, but the TMGN_map command doesn't work for me, or rather, with different combinations, the display changes from 321 to 32 and that's it. And if the TMGN_test command, it displays 1234 correctly and each time the command is sent, it shifts by three digits 3456 then 6789 and so on in a circle. And if I send the TMGN_print 0 0 1234 command, I see what's in the photo above.

    @p.kaczmarek2 and if I send the command TMGN_print 0 0 7654321 then I see 5672 on the screen Segment display showing the number 5672.

    Bad idea with the display. In general, I'll throw the project back in the drawer.

    You should not use TMGN_test for production. Just use:
    Code: text Expand Select all Copy to clipboard
    
TMGN_Map 32104567
TMGN_print 0 0 1234 

    Find the TMGN_Map that makes TMGN_print show 1234 correctly, I've seen you did that?

    pkaczmarek2 I I tried entering the command TMGN_Map but the changes occur only once, subsequent times when the combination changes numbers nothing changes. Or after each input do I need to reboot? Today I can spin all day under your commands.

    Since yesterday, the module stopped transmitting data via mqtt, in the logs I see that it uses a password, but I use the service without a password, and to save the configuration, you need to put some sign. Probably because of this, he stopped transmitting. If you leave the password blank, the previous one will be used.
    It is not possible to save an empty field. Could you help? Thank you

    Removed the commands and connected. What's wrong?

    Although the problem is that the readings are static, as soon as the sensor changes readings, it connects and sends data

Topic summary

The discussion revolves around integrating an SHT30 temperature and humidity sensor with a smart Tuya LED lamp utilizing a BK7231T processor. The user seeks guidance on the necessary firmware and connections for repurposing the LED lamp as a sensor. Responses include recommendations to flash OpenBeken firmware, connect the SHT30 sensor to specific pins (VDD, GND, SDA, SCL), and utilize UART1 for programming. Users share troubleshooting tips for Wi-Fi connectivity issues, configuring MQTT for data transmission, and managing LED functionality alongside sensor readings. The conversation also touches on the challenges of maintaining channel types for MQTT and the need for firmware updates to resolve conflicts between the LED driver and sensor operations. Ultimately, the user successfully configures the system to read temperature and humidity while controlling LED colors based on temperature readings.
