arrived, first experience is mixed:

• tuya-convert doesn't work because newer firmware version, so serial flashing is necessary
• opening is currently not possible, my only triangle screwdriver is too small - ordered a set of bits, should arrive on Monday

So, triangle bit set is arrived, the size 2.3 is fine, plug opened successfully (for more details look here).

There is an advice to de-solder the capacitor, which is blocking the straight access to the GPIO0 pad on the TYWE2S module - but this isn't really necessary, with a steady hand you can ground the pad with an jumper wire. I had only to remove the plastic cover to pass around the capacitor.

Flashing using Tasmotizer was successful, configuration and integration with MQTT broker too.
