    ok sorry all the be a pain but I am trying to figure out if I should even attempt this as I am not sure if Openbekten will work on a tuya fan or not I have a couple of tuya fans that run on version 1.2.2 FIRMWARE and 1.2.2 MCU I am including photos of the case and PCB I just want to get some input before I remove the module for flashing as I had to end up with a bricked fan if it won't operate on other than stock firmware

    assuming that unmarked module is Beken based, then I guess it's possible. Investigation and reading up on OpenBeken required.

    Maybe that module is a CB3S or a WB3S.

    Also, this looks like it might be a TuyaMCU with some surrounding test pads:

    I will see if I can get the firmware dumped this evening, and if so, will post it.
