Turn On the Light with Telegram

Learn how to use the Telegram Bot library, host a Telegram Bot on your NodeMCU Board, and use the messaging application (Telegram) to interact with your device.

It currently works on NodeMCU. You can view the last released Telegram API documentation here.

EXPANDED TECHNICAL DETAILS

Secure Bot-Based Home Control

This IoT project uses the Telegram messenger API as a highly secure, universal remote control for home appliances.

  • BotFather Integration: The ESP8266/ESP32 connects to a custom Telegram Bot. The Arduino firmware utilizes a "Secure Bot Token" to ensure only authorized users can send commands.
  • Command Parsing: When the user types /light_on in their Telegram chat, the Arduino receives the JSON message, extracts the command text, and triggers an opto-isolated relay.

Connectivity Feedback

  • Status Replies: After executing a command, the Arduino sends a confirmation message back (e.g., "Kitchen light is now ON"), providing the user with instant verified feedback from anywhere in the world.
