Building a Wired WLED RGB LED Controller with ESP32 and WIZnet W5500

Summary

This project is a fork of the popular open-source LED control firmware WLED, updated to work with the WIZnet W5500 Ethernet controller. WLED is widely used on ESP32 and ESP8266 devices to control digital RGB LEDs such as WS2812B, WS2811, SK6812, WS2801, and APA102. It provides a web-based UI, more than 100 LED effects, palettes, presets, segments, OTA updates, HTTP/JSON APIs, MQTT, Art-Net, DDP, Hyperion integration, and other network-based control interfaces. By adding W5500 Ethernet support, this project explores how WLED can be used in a more stable wired network environment, especially for permanent LED installations, smart lighting, media lighting, and event lighting systems.

Project Overview

WLED-W500 is a GitHub project published by stcalica and forked from the original WLED project. WLED is a fast and feature-rich web server implementation for ESP32 and ESP8266 devices, designed to control NeoPixel-style LEDs such as WS2812B, WS2811, and SK6812, as well as SPI-based chipsets such as WS2801 and APA102.

The key purpose of this fork is to update WLED to work with the WIZnet W5500 chip. In other words, it brings wired Ethernet connectivity to a WLED-based ESP32 LED controller, expanding the project beyond Wi-Fi-only installations.

WLED already provides a browser-based interface for controlling colors, brightness, effects, segments, presets, and device settings over the network. It also supports more than 100 effects, FastLED palettes, up to 250 presets, OTA software updates, NTP-based timers, and multiple integration interfaces.

This project is meaningful because it combines WLED’s rich LED control ecosystem with W5500’s hardware TCP/IP-based Ethernet connectivity.

Project Configuration

The project can be understood as the following system architecture.

Hardware Configuration

Software Configuration

WLED supports multiple control interfaces, including Android and iOS apps, JSON and HTTP APIs, MQTT, E1.31, Art-Net, DDP, TPM2.net, Hyperion, UDP realtime, Alexa voice control, and more.

Key Features

1. Rich LED Control Features from WLED

WLED is not just a simple LED on/off controller. It includes more than 100 WS2812FX effects, FastLED noise effects, over 50 palettes, segment control, RGBW strip support, and up to 250 user presets.

2. Web-based LED Control

Because WLED runs as a web server on the ESP32, users can control the LED strip directly from a browser. Color, brightness, effects, segments, and configuration settings can all be managed over the network.

3. Integration with External Systems

WLED supports HTTP/JSON APIs, MQTT, Art-Net, DDP, Hyperion, UDP realtime, and Alexa voice control. This makes it suitable for smart homes, media lighting, event lighting, stage lighting, PC ambilight systems, and automation platforms.

4. Wired Ethernet with W5500

The unique point of this fork is that it is updated to work with the W5500 chip. By using W5500, a WLED-based ESP32 controller can be connected through wired Ethernet instead of relying only on Wi-Fi. This is especially useful in environments where wireless signals are unstable or where long-term installation reliability is required.

Why WIZnet W5500 Was Used

WIZnet W5500 is a strong fit for this project because network stability is important in LED control systems.

WLED uses various network-based features such as the web UI, HTTP API, JSON API, MQTT, Art-Net, DDP, and Hyperion integration. These features depend heavily on stable network connectivity. Wi-Fi is convenient, but it can be affected by interference, congestion, and signal strength issues in venues, exhibition halls, commercial spaces, smart homes, and industrial environments.

The W5500 is a Hardwired TCP/IP stack Ethernet controller from WIZnet. It connects to an external MCU through SPI and integrates 10/100 Ethernet MAC and PHY in a single chip. It also supports TCP, UDP, IPv4, and other protocols, up to 80 MHz SPI, and 8 independent hardware sockets.

With W5500, the ESP32 can focus on LED effects, UI handling, and application logic, while the W5500 provides stable wired Ethernet connectivity. For real-time lighting, media synchronization, permanent installations, and multi-node LED systems, W5500-based Ethernet can be a practical alternative to Wi-Fi.

Scalability and Future Applications

1. Smart Home Lighting

Because WLED supports MQTT and APIs, it can be integrated with platforms such as Home Assistant, Node-RED, and custom automation servers. W5500 Ethernet can make smart lighting nodes more stable in home networks.

2. Commercial LED Installations

Stores, showrooms, signage systems, and exhibition booths often require LED controllers to run continuously for long periods. Wired Ethernet can be easier to manage and more reliable than Wi-Fi in these environments.

3. Media and Ambilight Systems

WLED can be used with Hyperion, UDP realtime, and DDP for media-reactive lighting. Hyperion documentation also describes WLED devices as controllable through Wi-Fi, Ethernet, or serial connectivity.

4. Stage and Event Lighting

Because WLED supports Art-Net, E1.31, DDP, and other lighting-related interfaces, it can be used in event lighting and stage lighting applications. For multi-node lighting systems, wired Ethernet can provide a more predictable network environment.

5. PoE LED Controller Development

In future versions, W5500 Ethernet could be combined with a PoE module to build LED controllers that receive both data and power through a single Ethernet cable. This would be useful for ceiling installations, wall-mounted LED systems, exhibition structures, and signage applications where power wiring is difficult.
