Configuring Tuya Ceiling Fan (BK7231N) with OpenBeken - Need Setup Guidance

I have a TUYA ceiling fan (Chipset BK7231N) successfully flashed with OpenBeken. I'm not sure how to set it up though.
I managed to map the controls. Would anyone be willing to help me with the configuration?

Property device from TUYA:

Light Switch: ID:20 - Bolean
Light WorkMode: ID:21 - enum
Brightness: ID22 - Value (10-1000)
Light Temperature: ID23 - Value (0-1000)
Timer: ID:26 - Value (0-86400)

Fan Switch: ID60 - Bolean
Fan Speed: ID62 - Value 1-16
Fan Direction: ID63 - enum
Fan Countdown Left: ID:64 - unit 0-540min
Fan Beep: ID66 - Bolean

I try to start Driver MCU, link datapin 20 to 1, but it does nothing.

startDriver TuyaMCU
linkTuyaMCUOutputToChannel 20 1

Added after 1 [hours] 51 [minutes]:

So i found autoexec....

Light On/Off is working:

linkTuyaMCUOutputToChannel 20 1
setChannelType 1 toggle
addEventHandler OnChannelChange 1 backlog TuyaMCU_SendState 20 1 $CH1; publish stat/device/light $CH1
setButtonLabel 1 Svetlo

But brightnes not:

linkTuyaMCUOutputToChannel 22 2 #
setChannelType 2 range
addEventHandler OnChannelChange 2 backlog TuyaMCU_SendState 22 2 $CH2; publish stat/device/brightness $CH2
setButtonLabel 2 "Jas"

LOG says:

Info:TuyaMCU:Received: 55 AA 03 07 00 08 16 02 00 04 00 00 00 64 91
Info:TuyaMCU:ProcessIncoming[v=3]: cmd 7 (State) len 15
Info:TuyaMCU:ParseState: id 22 type 2-val len 4
Info:TuyaMCU:ParseState: int32 100
Info:GEN:No change in channel 0 (still set to 0) - ignoring

Added after 39 [minutes]:

So, this looks like its working:

linkTuyaMCUOutputToChannel 22 2
setChannelType 2 dimmer1000
addEventHandler OnChannelChange 2 backlog publish stat/device/brightness $CH2; TuyaMCU_SendState 22 2 $CH2
setButtonLabel 2 Jas

But from some reason, when i set for example value 500 of brightness, it will automaticly instatntly reset to 0.... Dont know why....

Which tuta fan if I may ask? And how did you flash it
