DIY Smart Relay Controller with ESP-NOW + LVGL UI (ESP32 + ESP12F)

In this project, I combined ESP-NOW, LVGL UI, and SPIFFS to build a wireless relay controller with an intuitive touchscreen interface. The main controller is an ESP32 running a beautiful LVGL UI, which communicates with an ESP12F board (ESP8266) to toggle relays wirelessly via ESP-NOW protocol.
