Docker Monitor with ESP8266

A physical dashboard that monitors server status in real-time via an OLED screen, web panel, and a custom-developed REST API.

A Flask backend reads container status from the Docker socket and exposes it as a REST API. An ESP8266 with an OLED screen polls that API and displays it, using page-buffered rendering to work around the device's limited RAM.
