    Wow, BL602? That's something new. And as far as I can tell, that's not just a Sonoff S40 clone (S40 is using BL602, as far as I know). That's interesting, I haven't found any BL602-based eWeLink devices yet. I think I only saw a BL602-based RGBCW bulb somewhere, but just once.
    Thank you for posting.

    Do you remember where have you bought that switch module?

    You might consider using "TglChannelOnToggle" role instead of Button, this will work with "classic" two state switches

    First of all, kudos for your work on OpenBeken etc.

    Let me add a description of flashing my version of this gadget.

    I bought it on Ali in the AUBESS store - the offers are no longer valid, but you can find similar or cheaper.

    I also bought Wireless Stick-on Smart Wall Switches for the switches:

    I uploaded with the DevLedCube program downloaded directly from the Buffalo Lab website:

    In addition, I downloaded the latest version of OpenBL602 from GitHub from the link:

    DevLedCub settings:

    Uploading with these settings went without a problem, I powered the system from the USB-->UART adapter - BOOT pin shorted to VCC by 10kOhm.
    After restarting, the Wifi network appeared and here it is standard with changing network settings, etc.

    Everything works as it should, but unfortunately, as I understand it, I deprived myself of "company" Wall Switches? Is there any way to add them?

    Hello, nomek!

    Thank you for sharing your experiences. Would it be possible for you to share a couple photos of the Aubess mini switch PCB? Maybe including one of the Buffalo chip?
    I'm a bit puzzled because i got a few of those but they all have a BK7231N and not a BL602.
    As for the weird part, in my case, there's reports (https://www.elektroda.com/rtvforum/viewtopic.php?p=20537140#20537140) cloudcutter would do the trick, with the BK7231N chip, but i had no success so far.

    Regards,

    Hugo.

    @hmonteiro my module is the same as in the photos in the first post and that's why I didn't attach photos so as not to duplicate materials.
