MQTT connection: Tuya luminaire with OpenBeken and Mosquitto server - control works on one side

Hello everyone,
Yesterday I installed my first Tuya light via Clouscutter with Openbeken, it worked shockingly well for the first time .
After a few attempts and tests, it now also lights up red on red etc. as desired.
I am now failing with the MQTT connection to my Mosquitto server. In the MQTT Explorer, when I switch via the Openbeken web interface, I can see that the value changes, unfortunately nothing works in the other direction, something comes in, but the lamp does not react to it.
Can someone possibly tell me what I am doing wrong or where I have forgotten something

Here are a few more pictures of the settings:

Have you performed Home Assistant Discovery correctly?
.

Hi, I don't use Home Assistant, so no, I haven't done this.

But I have found the error, cmnd is in an upper folder, there was no access set up in the ACL. I obviously can't switch via the set value or should that work too?

Unfortunately, this is a bit of a problem as my entire MQTT broker has this structure.

Type(tasmota/shelly..... )/
Name Device/
Data(tele/stat/cmnd/.......)



But OpenBK makes tele/ OpenBK / name / value
stat/ OpenBK/ name/ value
cmmd /OpenBK name / value



Is there any way to customise this so that I don't have to change my entire MQTT system setup? It would be a shame that it wouldn't work...

Hello,

I have now set up everything so far and it works.
Before I now flash all Tuya devices, is it correct that I can only switch via MQTT via point 1 and not via point 3? or do I still have errors in the config?

On my "Aubess mini switch" I do it as follows:

MQTT config: name OBK133/Power
Module config: PA 8 LED_n chann 1 LED (what else)
PA 24 Btn_Tgl_All S2 ( S1 is connected to N )
PA 25 Btn_Tgl_All Button
PA 26 Rel chann 1 L-out


Control relay via MQTT:
Tasmota device command:
----------------------
publish BK133/Power/1/set 1 switch on
publish BK133/Power/1/set 0 switch off

node-red injects:
-----------------
topic: BK133/Power/1/set msg: 1 switch on
topic: BK133/Power/1/set msg: 0 switch off
