Flirc-SE and power-on in S5

Hello,

I am pretty new to lirc and htpc stuff. I build a htpc with a asrock x570 phantom itx tb3, ryzen 4350g, streamcom F7C, streamcom nano160 psu and flirc-se (hard to find but streacom sent me one).

I use manjaro xfce as base, plus kodi with mpv as player. 

I tried today to make my remote to work. First when i start flirc guy in xfce it asked to update to latest firmware. I did it and then i map my buttons, including the power button of my remote under the "streamcom" tab. 

I check my bios, and there is a few option under the "ACPI Configuration" :

Suspend to RAM =} Auto

Deep Sleep =} Disabled

USB Mouse / keyboard power on =} Enabled

RTC Alarm Power On =} Disabled

And... when my htpc is off (S5) the power button of my remote do not start it. I also own a k400 bluetooth keyboard, it has a power on button with FN + inser key. If i understand it right, it should also power one my htpc as the bluetooth dongle is usb, but it doesn't.

I made some research and the only topic i found is this one : http://forum.flirc.tv/index.php?/topic/1651-power-toggle-triggering-with-streacom-version/

So i try this command to see what is happening :

The 5th key is well assigned to the power key but there is this "144" error.

Any idea ?
