Hello @Slyke
Tasmonizer did not work for me either. VSC/PlatformIO only worked with version 9.5.0. (Version 9.6.0 or master don't compile for me.)
Here are the steps:
Clone Tasmota: git clone https://github.com/arendst/Tasmota.git
Checkout 9.5.0: git checkout pre-release-9.5.0
Rename sample file: mv platformio_override_sample.ini platformio_override.ini
Open project in VSC/PlatformIO
Modify platformio_override.ini: comment out: tasmota / uncomment: tasmota32-core2
Compile & Link & Download from within VSC/PlatformIO
Note: there is nothing on the LCD screen at this point. I think the device is waiting to be configured.
