mqtt command sequence

[dahadd]

Hello everyone, I need your help.
I am too stupid to set a setting to the Faikin via MQTT

I would like to set the setting of the fan_mode “night”.
Unfortunately I don't know what to do.
Can someone please help me.

Update....
Solution:
Topic: command/Faikin-WZ/control
Payload: { "fan": "A" }

:-)
