## Article

#### Project Purpose

This project is designed to control up to 10 relays via a web interface using an ESP32-S3 microcontroller. The system supports multiple clients with asynchronous updates, allowing users to view and control the state of each relay in real-time. Additionally, the project can manage temperature zones for radiant heating or forced air systems, incorporating temperature sensors to automate the control of these zones.

#### Key Features

**Web Interface for Relay Control**

- Displays the state of all 10 pumps (relays/output pins) on a webpage with user-selectable mode changes (Auto, On, Off).

- Output pins can be easily configured individually as on=high/off=low or on=low/off=high.

**Network Connectivity**

- Uses a W5500 Ethernet adapter connected to the ESP32-S3-DevkitC-1 microcontroller for network connectivity.

- The W5500 is used because it offers stable and reliable Ethernet connectivity with low power consumption and supports high-speed SPI communication, which is ideal for the ESP32-S3's capabilities.

**RTC and NTP Synchronization**

- Utilizes the DS3231 RTC to synchronize system time with NTP (Network Time Protocol).

- System time is broadcast every second through a websocket and is available system-wide to ensure all times are synchronized.

**File System and Logging**

- Uses the LittleFS file system to store favicon icons and log files.

- Implements a full logging system to track pump run times on a daily, monthly, and yearly basis.

- Logs are managed to minimize file size by aggregating data and deleting source logs periodically.

**Additional Web Page**

- Provides a second webpage at `/second-page` where elapsed pump runtimes can be viewed for the current day, month, year, and total.

**Code Organization**

- Code is organized into multiple separate files based on function for better manageability and readability.

#### Major Use Cases

- **Heating System Control:** Automate and control heating systems using multiple zone valves or dampers.

- **Real-time Monitoring:** Monitor and control relay states in real-time via a web interface accessible by multiple clients.

### Additional Information on W5500

The W5500 Ethernet adapter is a key component in this project for the following reasons:

1. **Stable Ethernet Connectivity:** Provides a stable and reliable connection to the network, which is crucial for real-time control and monitoring.

2. **Low Power Consumption:** The W5500 is designed to consume low power, making it efficient for continuous operation.

3. **High-Speed SPI Communication:** Supports high-speed SPI (Serial Peripheral Interface) communication, which aligns well with the capabilities of the ESP32-S3 microcontroller, ensuring fast and efficient data transfer.

4. **Ease of Integration:** The W5500 is easy to integrate with the ESP32-S3, simplifying the hardware setup and software development.

This project, developed using the Arduino IDE, combines an intuitive web interface with a robust logging system, making it versatile for various applications.
