Suggests the UBTW01B comes with a TYWES3 module, however mine came with a CB3S which doesn't appear to use an ESP32. Is it possible to swap mine with a TYWES3 or should I just return it?

Here's a picture of what I have

I tried flashing with tasmotizer, however it wouldn't connect, then I realized the chip was different and most likely not supported.

Awesome! I'll give this a shot.

I noticed this flasher only comes with E or F versions. https://www.amazon.com/DORHEA-Firmware-Downloader-Downloade-Compatible/dp/B08P37JQYX

Should I go with that or buy the S version then solder and program it in place after I swap the chip?

I ran into the same thing. Instead of swapping the module for an ESP, I used OpenBeken and flashed the existing module.

I created a teardown with instructions and pictures here: https://www.elektroda.com/rtvforum/viewtopic.php?p=20612154#20612154
