Remote-ESP32: Simplify IoT Projects with OTA Updates and Web Control

Remote-ESP32 is a versatile IoT framework that empowers ESP32 projects with seamless sensor integration, OTA updates, and web-based control. The Remote-ESP32.ino file configures an ESP32 as an access point (AP), offering OTA update capabilities through a built-in web server. This framework harnesses the ESP32's dual-core architecture, enabling multitasking between OTA handling and custom application logic.

Key Features:

  • Sensor Integration: Effortlessly incorporate various sensors into your projects, such as a soil moisture sensor for real-time monitoring.
  • Web-Based Control: Access the user-friendly web interface to monitor sensor data, control devices remotely, and trigger actions.
  • OTA Updates: Ensure secure Over-The-Air (OTA) firmware updates with password-protected web interfaces.
  • Update, delete, download the web interface, style.css file and any other project files.
  • Efficient Multitasking: Leverage the ESP32's dual-core architecture for parallel execution of OTA update handling and your unique application logic.

How to Use:

  1. Download and unzip the repository.
  2. Open Remote-ESP32.ino in the Arduino IDE.
  3. Modify variables (e.g., SSID, PASSWORD) to match your network settings.
  4. Edit your application-specific code in mymain.h (separate tab on the IDE)
  5. Edit html and style files to suit
  6. Upload the code to your ESP32 board.
