ESPHome 2026.9.0: Faster builds and encrypted updates

A Dual-Path IoT Sensing and Communication Framework for Smart Building and Construction-Site Structural Monitoring

Build and hardware-test project for MeshCore on the RAK10720 / RAK4631 + RAK13800 + RAK19018 PoE Ethernet gateway.

A multitasking ZX Spectrum OS drives WIZnet's W5300 using plain Z80 IN/OUT instructions, enabling ping, telnet, browsing, and network games.

An universal DIN-rail controller powered by the ESP32-S3. It features 8 digital inputs, 8 digital outputs, and communication interfaces

SqueezeAMP PoE is an amplifier driven by an ESP32 designed to run squeezelite-esp32, powered by PoE++.

ESP32-S3 + W5500 connects TDT-1001 LiFePO4 BMS data to ESPHome and Home Assistant, including multi-pack monitoring over one RS-232 link.

This project targets an embedded machine-vision architecture in which an OV2640 camera captures image data and an MCU forwards that data over wired Ethernet usi

This project uses an STM32 microcontroller with the WIZnet W5500 to provide wired 10/100 Ethernet connectivity through SPI.

Inside pw-esp-bacnet-proxy, an open-source project that connects existing Delta heating and cooling controls to a locally managed smart home.

UnreaLin01's mlx90640-rp2350-stream reads an MLX90640 thermal array on a WIZnet W6300-EVB-Pico2 and ships raw sensor data to a PC over USB or UDP.

Freshtrack

A Paderborn University lab BMS runs a Modbus TCP server on a W5500 hardware socket, port 502, so a ROS 2 node reads cell data and publishes BatteryState.

Kontrx is a bare-metal STM32F407 + FreeRTOS industrial edge gateway for water-quality monitoring. It doesn't just "have Ethernet"

Bringing Legacy Sony RS-422 Camera Control onto Ethernet with W7500P

Network MIDI 2.0 C++17 library — binary release (AmeNote Inc.)

This project uses a Raspberry Pi Pico and WIZnet W5500 to extend a Flight Controller’s MAVLink communication over Ethernet.

an UniFLEX compatible hardware/software project on Eurocards

A Chinese supercomputing institute's network data encryption card routes its protocol communication through the W5500's hardwired TCP/IP stack.

Custom RP2354B computer runs its own OS and drives WIZnet W5100S directly over SPI, implementing hardware sockets, blocking I/O, and a TCP server.
