This remix replaces the original front panel and custom LED PCB with four 12 mm illuminated waterproof push buttons (3V–6V LED version). The buttons connect directly to the ESP32 GPIOs, while the LED rings use the relay GPIOs to indicate the relay status. It's a simpler build that requires no custom PCB and is ideal if you prefer off-the-shelf components.

Built-in LED ring indicates relay status
