API Multi instances

[Leguman31]

Hello, i have 2 instances (led stripes).
I ccreated a Windows Form in C#. I inject Jsaon using HyperHDR API, but i can't change color for the second instance.
Only first instance turn red/green with this code.

Do you have an idea ?

`using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace HyperHDRController
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

    // Button for Instance 0 (Green)
    private async void BtnVert_Click(object sender, EventArgs e)
    {
        // Switch to Instance 0 and activate its LEDs
        await SelectInstanceAndActivate(0);

        // Send the color command (Green)
        await SendColorCommand(0, 255, 0);
    }

    // Button for Instance 1 (Red)
    private async void BtnRouge_Click(object sender, EventArgs e)
    {
        // Switch to Instance 1 and activate its LEDs
        await SelectInstanceAndActivate(1);

        // Send the color command (Red)
        await SendColorCommand(255, 0, 0);
    }

    // Method to switch to a specific instance and activate its LEDs
    private async Task SelectInstanceAndActivate(int instanceIndex)
    {
        // Command to switch to the specified instance
        string switchInstanceCommand = $@"
        {{
            ""command"": ""instance"",
            ""subcommand"": ""switchTo"",
            ""instance"": {instanceIndex}
        }}";
        await SendHyperHDRCommand(switchInstanceCommand);

        // Command to activate the LEDs for the selected instance
        string activateLedsCommand = @"
        {
            ""command"": ""componentstate"",
            ""componentstate"": {
                ""component"": ""LEDDEVICE"",
                ""state"": true
            }
        }";
        await SendHyperHDRCommand(activateLedsCommand);
    }

    // Method to send a color command to the current instance
    private async Task SendColorCommand(int r, int g, int b)
    {
        string colorCommand = $@"
        {{
            ""command"": ""color"",
            ""color"": [{r}, {g}, {b}],
            ""priority"": 50
        }}";

        await SendHyperHDRCommand(colorCommand);
    }

    // Generic method to send commands to the HyperHDR API
    private async Task SendHyperHDRCommand(string jsonCommand)
    {
        string url = "http://localhost:8090/json-rpc"; // Replace with your HyperHDR's URL

        using (HttpClient client = new HttpClient())
        {
            try
            {
                var content = new StringContent(jsonCommand, Encoding.UTF8, "application/json");
                HttpResponseMessage response = await client.PostAsync(url, content);

                if (!response.IsSuccessStatusCode)
                {
                    MessageBox.Show($"Error while sending: {response.StatusCode}");
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show($"Error: {ex.Message}");
            }
        }
    }
}

}

Hi
You must change the instance and set color in the same request/session. It can be done using curl but I'm not sure about c#. And alternatively using combine GET requests (the example you have in the Advanced->JSON API tab at the beginning).

So i find a solution using C#, i can change for each instance the color and it works really good :)
Thank you
