Generting Tuya IR codes from NEC hex codes

So, I got a Moes Tuya TS1201 IR blaster to control some dumb devices via IR signals in HA. It works fine when learning codes from a remote. But I now want to use it for an Acer H6510BD projector. The remote does not exist anymore, so I am trying to create the necessary commands from the hex codes I found at an Acer support page. It says that it uses the NEC protocol.

Now I tried to convert these codes using different ways I found online, for example this solution. Yet, the generated codes do not work with the projector. For example. the code for power (10C8E11E) is encoded to AygjlBEfMAI1AjACNQIwAjUCMAI1AjACNQIwAjUCMAI1AjACNQIfMAI1AjACNQIwAjUCMAI1AjACNQIwAjUCMAI1AjACNQIfMAI1AjACNQIwAjUCMAI1AjACNQIwAjUCMAI1AjACNQIBMAI=, but other codes lead to the exact same results. I also tried using the tool irgen but can’t seem to get the input right.

Does anyone have a hint on how to correctly do the encoding? Thanks a lot in advance!
