Smart Relay PCB design, testing & debugging and verification

I need a brand-new hardware design built around an ESP8266 (NodeMCU class) / ESP32 that can drive five independent 240 VAC relay channels. The board must let me control everything over Wi-Fi through ESPHome/Home Assistant while still working perfectly with the existing wall switches...
