Can I upgrade only liquidctl.exe?

[sp00n]

I have an NZXT Controller hub that apparently is not recognized by this plugin.
Executing the included liquidctl.exe with liquidctl.exe list --debug also showed nothing (and a version number 0.0.0-unknown?), so I went to the liquidctl repository and downloaded and build the latest revision, which then did show two recognized units:

• NZXT RGB & Fan Controller (3+6 channels)
• NZXT Kraken 2023 Elite (broken)

I actually wanted to control the Fan Controller, so it should be fine, however the plugin still doesn't recognize anything in Fan Control after having replaced the liquidctl.exe with the newly built one.
Do I need to compile the whole project again, or does the code of the DLL itself also need to be updated to support anything new that has been added to liquidtctl?

Ok, after digging further, the new liquidctl version returns a string value for a status entry ("Fan x control mode"), whereas the DLL only expects float values there:

Result from liquidctl --json --address {address} status:

[
    {
        "address": "\\\\?\\HID#VID_1E71&PID_2011#7&3b3f9bd5&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}",
        "bus": "hid",
        "description": "NZXT RGB & Fan Controller (3+6 channels)",
        "status": [
            {
                "key": "Fan 1 control mode",
                "unit": "",
                "value": "DC"
            },
            {
                "key": "Fan 1 duty",
                "unit": "%",
                "value": 25
            },
        ]
    }
]

The class used for deserializing the result LiquidctlStatusJSON.cs, which expects float as the value type:

using System.Collections.Generic;
namespace FanControl.Liquidctl
{
    public class LiquidctlStatusJSON
    {
        public class StatusRecord
        {
            public string key { get; set; }
            public float? value { get; set; }
            public string unit { get; set; }
        }
        public string bus { get; set; }
        public string address { get; set; }

        public string description { get; set; }

        public List<StatusRecord> status { get; set; }
    }
}

[sp00n]

I fixed this issue by replacing public float? value { get; set; } with public dynamic value { get; set; }

There are other issues however, the current plugin can't handle outputs for multiple fans, e.g. "Fan 1 speed", "Fan 2 speed", etc.
I tried to fix this in my modded version, but since I have no real idea about C#, I'm not creating a PR for this. It seems to work though.
