Nắp trước nút nhấn chống nước có đèn cho vỏ ESP32 relay 4 kênh

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.

Features

• No custom LED PCB required

• Uses standard 12 mm illuminated waterproof push buttons

• Built-in LED ring indicates relay status

• Same enclosure and ESPHome configuration as the original design

• Perfect for workshop, garage, or outdoor installations

Note: This remix only includes the alternative front cover. All other enclosure parts are the same as the original project.
