Добрый день. Прошу помощи. Не могу до конца склеить в работоспособном состоянии два скетча.

Один из примеров в ide называется OTAWebUpdater    для платы esp32 (у меня devkitv1)

и любой скотч для управления реле (достаточно одним).

Идея такова. Заливать прошивку через web.

#include <WiFi.h>
#include <WiFiClient.h>
#include <WebServer.h>
#include <ESPmDNS.h>
#include <Update.h>

const char* host = "esp32";
const char* ssid = "xxx";
const char* password = "xxxx";

WebServer server(80);

/*
 * Login page
 */

const char* loginIndex =
 "<form name='loginForm'>"
    "<table width='20%' bgcolor='A09F9F' align='center'>"
        "<tr>"
            "<td colspan=2>"
                "<center><font size=4><b>ESP32 Login Page</b></font></center>"
                "<br>"
            "</td>"
            "<br>"
            "<br>"
        "</tr>"
        "<tr>"
             "<td>Username:</td>"
             "<td><input type='text' size=25 name='userid'><br></td>"
        "</tr>"
        "<br>"
        "<br>"
        "<tr>"
            "<td>Password:</td>"
            "<td><input type='Password' size=25 name='pwd'><br></td>"

            "<br>"
        "</tr>"
        "<tr>"
            "<td><input type='submit' onclick='check(this.form)' value='Login'></td>"
