Home Automation Using Telegram Bot and ESP32

This project demonstrates how to build a smart home automation system using an ESP32 microcontroller and a Telegram Bot. Users can control various devices such as lights, fans, and other appliances using a Telegram bot interface.Features include GPIO management, Wi-Fi connectivity, MQTT/HTTP protocols, real-time updates, and secure access using Telegram's API.

---

Features

• Control up to 16 devices via Telegram bot.
• Individual ON/OFF and All ON/All OFF commands.
• Secured access using predefined chat IDs.
• Status feedback with visual symbols (✅ for ON, ☑ for OFF).

Getting Started

Follow these steps to set up the project and run it on your ESP32.

1. Hardware Requirements

• ESP32 Microcontroller Board
• WiFi connection
• 16 output devices (e.g., LEDs, relays for appliances)
• Breadboard and jumper wires
• USB Cable for ESP32 programming
• Power source for connected devices

---

2. Circuit Diagram

Connect the output pins on the ESP32 (13, 14, 12, ...) to the respective devices (LEDs or relays).

Example Circuit

Insert an image of your circuit here.
Upload your circuit diagram (e.g., from Fritzing or hand-drawn).

---

3. Software Requirements

• Arduino IDE (with ESP32 board support installed)
• Telegram app on your smartphone
• Git (optional for cloning this repository)

---

4. Installation

Step 1: Clone the Repository

git clone https://github.com/Ganesh-Solapure/Home-Automation-Using-Telegram-Bot-ESP-32.git
cd Home-Automation-Using-Telegram-Bot-ESP-32

Step 2: Install Libraries

Ensure you have the following libraries installed in Arduino IDE:

• WiFi
• WiFiClientSecure
• UniversalTelegramBot

Step 3: Configure Credentials

Update the following details in the code:

#define BOTtoken "Your_Telegram_Bot_Token"
char ssid[] = "Your_SSID";
char password[] = "Your_WIFI_Password";

Step 4: Upload Code to ESP32

1. Connect ESP32 to your computer.
2. Select the correct board and COM port in Arduino IDE.
3. Click on Upload.

5. Using the Telegram Bot

1. Open Telegram and search for BotFather to create your bot.
2. Save the API token provided by BotFather and update it in the code.
3. Add your bot to a chat or group.
4. Use commands like /start, /switch, /AllOn, and /AllShutDown to interact with the devices.

Commands Overview

Command	Function
/start	Displays welcome message and options
/switch	Opens the switchboard interface
/AllOn	Turns ON all connected devices
/AllShutDown	Turns OFF all connected devices

---

Troubleshooting

Common Issues

1. WiFi not connecting: Verify SSID and password.
2. Bot not responding: Ensure the bot token is correct and check internet connectivity.
3. Devices not working: Check the wiring and power supply.

Future Improvements

• Add scheduling features for device control.
• Integrate sensors (e.g., temperature, motion detection).
• Expand to support more devices.
