A beginner question here. There are two firmware versions: one for BK7231T and BK7231N. I am trying to flash my MOES dimmer module (Model 105B) using the Tuya cloudcutter method. Is there a way to find out which chip version is in my device? Thanks for the help

seems like MO105B rely on WB2S module so it's a T. After that don't worry if you try the incorrect model on tuyacloudcutter. it will just not work as each model has different cypher key.

As far as I know there is no reliable way to do it. You just could try Cutter profiles at random and wait until one works, but in my opinion it would be faster to just open the case.

How to find out which chip inside my device without opening it?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
