For my home cinema setup I use a Projector Screen "iVisions Electro M"
https://www.projectieschermen.com/electro-m-series-projectiescherm.html
It uses a single channel RF remote control AC123-01 which also seems to be available in a 2, 6 and 16 channel version. A Goolge search reveals the remote is also used by A-OK branded blinds.
The RF protocol is currently not supported, thus I’m giving it a try to implement the protocol. However, I’m not able to make it work.
The problem is that each time I send a command from the remote control, the code differs a bit.
For now I’m focussing on the stop command, the idea is that if I have one command working I will be able to make the other works as well.
These are codes I receive when I press the stop button on the remote:

Pulse widths are [ 152, 211, 598, 5103 ]
As you can see, they differ all a bit. I tried to replay a message using the raw switch implementation I created earlier, but when I send one of the above messages the screen does not stop
Does anyone have a suggestion on how to solve this mystery?
