    Hello,
    Can you please build a cloudcutter profile for this BK7321N device? None of the profiles I tried worked for me. I have 5 more devices to program and they are quite tricky to disassemble.

    It's from a generic 6 gang smart WiFi switch (but there are actually 2x 3 gang modules side-by-side).

    Name: generic Tuya 3 gang Wi-Fi Smart Switch
    Chip: BK7321N
    MCU version: v1.0.1
    Close-up of the BK7321N chip on a circuit board.
    Full binary attached.

    I ended up soldering directly to the serial connection and reprogramming it that way.

    The cheap Chinese smart wifi touch switches that used this chip and firmware were terribly unreliable and half of the 6 units have failed within one year of average domestic use.

    Do yourself a favour, don't buy this kind of thing from eBay or Alibaba. Buy a reputable brand from a reputable supplier. Otherwise you'll just end up having to pay twice, once for the cheap rubbish that fails, then a second time for something that works.
