Tuya Convert doesn’t seem to work. The device is ultrasonically welded. I have managed to flash it by disassembling the device, desolderin the PCB, and soldering wires to the pins on the TYWE2S module. You might also have success with the test points on the back of the module, but that isn’t exactly easy given the cramped PCB layout.
