Project description

Overview Velmurugan K L shares software, dashboard, and automation projects on GitHub, and Server_CTRL brings several of those interests together in one home-lab control stack. The project uses an ESP32 with a WIZnet W5500 Ethernet module to control a server, router, and NAS through local REST calls, MQTT commands, and Dell iDRAC Redfish requests. Generated technical diagram: ESP32 and W5500 sit between local apps, MQTT, iDRAC, and home-lab devices. The repository is not just a single Arduino sketch. It includes ESP32 firmware, a React MQTT dashboard, an Android TV control app, and a small…
