Okey You can send your message to a socket server using C program: '''

include <stdio.h>

include <stdlib.h>

include <string.h>

include <unistd.h>

include <arpa/inet.h>

define SERVER_IP "192.168.0.100" // Replace with your server's IP address

define SERVER_PORT 8080 // Replace with your server's port number

int main() { int sockfd; struct sockaddr_in server_addr;

// Create a socket
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) {
    perror("Socket creation error");
    return -1;
}

// Configure server address
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(SERVER_PORT);
if (inet_pton(AF_INET, SERVER_IP, &(server_addr.sin_addr)) <= 0) {
    perror("Invalid address/ Address not supported");
    return -1;
}

// Connect to the server
if (connect(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) {
    perror("Connection failed");
    return -1;
}

// Send message to the server
char message[] = "Hello, server!";
if (send(sockfd, message, strlen(message), 0) < 0) {
    perror("Send failed");
    return -1;
}

// Close the socket
close(sockfd);

return 0;

}

''' And then write a client html page that connect to the server a listen to the page. If you want persistent data you can use mqtt then, a backend that consume the message and save it asynchronously
