{"NAME":"Xystec USB Hub","GPIO":[0,0,0,0,224,0,0,0,226,227,225,0,0,0],"FLAG":0,"BASE":18}

The device needs to be flashed via serial - tuya convert does not work:

• open the hub carefully on the front and back « front only should be fine (power button), PCB slides out after that, maybe push USB ports gently (Rev2_2022_02_17)
• pull the board out of the case
• the pinouts are clearly accessible and visible - no soldering required

USB serial programmer	board
RX	TX
TX	RX
GND	G
GND	IO0
GND	RST (required) «  not necessary for my “Rev2_2022_02_17”

Power the board over USB.

• plug the hub into usb to power it on
• plug the serial programmerr into the computer
• (wait a few seconds,) remove the RST connection - flashing mode « not working for my “Rev2_2022_02_17” instead, for backup with Tasmotizer remove the IO0 connection worked, for erasing & flashing all 4 had to be connected
• flash the device as usual
• apply the template
