lightyear_hub – A Multi-Protocol IoT Sensor Gateway Powered by W5500 Ethernet
A gateway device designed for BLE and Zigbee sensor cloud telemetry
COMPONENTS
PROJECT DESCRIPTION
lightyear_hub is an open-source IoT gateway that collects data from BLE and Zigbee sensors and uploads it reliably to the cloud using WIZnet W5500 Ethernet.
Built on top of the ESP32-C6 platform, the project integrates BLE, Zigbee, Wi-Fi, and Ethernet into a single unified gateway that brings stability, flexibility, and low power consumption to sensor-based IoT systems.
