    Good morning,
    I have a QNCX brand smart plug (https://fr.aliexpress.com/item/1005005374840269.html?spm=a2g0o.order_list.order_list_main.24.29d95e5beB7gQG&gatewayAdapt=glo2fra) with energy measurement but I can't find it model in the database it looks a lot but doesn't have a map like the other models if someone can help me install openbeken that would be great
    I am attaching all the images and photos
    Thank you and see you soon.

    I think I recognize this device. It's a bit harder to flash than usual. You can find more info about that in the following thread:
    [T34/BL0937] Teardown Generic Wifi Smart Plug with Energy Measurement
    As you can see, no programming header is available there. You need to solder to QFN pins:

    You can also search more information for T34:

    Alternatively, you can use the method with desoldering whole T34 from the board, which can be found here:

    Once flashed correctly, you can use this method to try extracting GPIO config:

    I tested this method but I got an error when I imported the file it says "the file is not an OBK config file", I will test again

    This error sounds strange. Maybe you're importing wrong file or importing it in the wrong place.

    There are indeed devices without Tuya config but the error message is different then.

    Hi, there is the same device already in this topic: https://www.elektroda.com/rtvforum/topic4042412.html

    the message is " fail to extract keys"

    I think message this is about the Tuya .json config file. It could not be extracted. Perhaps because it's not getting created before.

    How is your socket doing after a year? I started having problems: after the electricity was restored, it doesn't start (only the blue LED is slightly lit), but the relay doesn't start and it doesn't connect to Wi-Fi. After a series of repeated on-off switches, it starts. On average, this happens in 5% of cases. What could be the reason? The chip was changed to esp-02s, nothing changed. Is the problem somewhere in the power line? How can I check? Thank you.

    I guess you didn't have OpenBeken's PowerSave enabled. Check out this guide:
