Unsupported Generic LED Function with Lighting Node PRO + Suuport for it?

[kalinda99]

I don't know if this counts as a bug or not since the hardware I'm using isn't on the supported list but OpenCorsairLink does detect my Lighting Node Pro, maybe because it's similar to the Commander Pro? The only difference between them, as far as I know, is that the Lighting can't control fan RPM, it's just for the pretty RGB.

Anyway, I'd love to see support added for the Lighting Node Pro if there is none. I'd be happy to do testing or get whatever info would be needed for it.

Describe the bug
When I execute the command sudo OpenCorsairLink --dev=1 --led channel=2,mode=4,colors=00FF00, I get Unsupported Generic LED Function at the end. Here's the full output:

Unsupported Generic LED Function`

It detects all six of my fans, though it doesn't talk to them, or maybe it's just detecting that the device supports six fans.

Expected behavior
To control my lights just like I can with my H100i. Maybe I'm doing it wrong? I tried several different modes and combos and I just get that error.

Desktop:

• OS: Arch Linux with kernel 5.4.13
• Version: I'm using the testing branch package from Arch's AUR, which I just rebuild today so I have the most recent commits.

LED protocol for the Lighting Node Pro (and the Commander Pro) isn't fully mapped yet.

I was going to ask a similar question, I guess... The error message is a bit different.
I'm a newbie in Linux and I made a mistake of buying 6 freaking LL fans which have RGB with it even tho I keep them black (no color) on windows.

I can see that it's recognizing the fans that are attached to the CoPro and the RPM of it unlike the creator of this topic.

Also I guess I screwed up the installation, kinda hard for me.

Di you manage to get anywhere with this @audiohacked ? Running elementaryOS 5.1 am in the testing branch but the LED side of the commander pro doesnt seem to be getting recognised

I can confirm the observation of @kalinda99 and @BeardedDevCo. I have the Lightning Node Pro connected to my Commander Pro and the output is the same. Since development is moving to liquidctl it is likely that we will get the feature there.
If I have some spare time I might have a look at it. For now you can also try to use OpenRGB for the LEDs and OCL for fan speed.
