GPIO Pinout

PinFunction
GPIO0Push Button (HIGH = off, LOW = on)
GPIO12Relay and its status LED
GPIO13Blue LED (HIGH = off, LOW = on)
GPIO1RX pin (for serial programming)
GPIO3TX pin (for serial programming)

Basic Configuration

As the only controllable LED is the Blue LED, it is configured here to use the status_led light component, which will take over the LED in the event of a error/warning state, such as when WiFi is disrupted.
