A maker project where an ESP32 microcontroller hosts a publicly accessible website at HelloESP.com. The first version ran entirely on the ESP32 using a SPIFFS filesystem and achieved 500 days of uptime before hardware failure. The relaunched version uses an ESP32-WROOM-32D with environmental sensors (BME280, CCS811) and a DS3231 RTC. To avoid port forwarding, the ESP32 maintains an outbound WebSocket connection to a Cloudflare Worker, which routes HTTP requests to the device and serves a static fallback page during connectivity issues.
