ESP32-C3 button and LED
Use Remocon esp32c3-button-led with the ESP32-C3 Dev Module board profile and Bounce2. The onboard LED is GPIO8, active LOW. BOOT is GPIO9, configured as INPUT_PULLUP; pressed is LOW. Release BOOT for normal startup after flashing.
Set Wi-Fi credentials and io.remocon.kr:55488. In the workbench, connect to wss://io.remocon.kr/ws and choose the C3 preset. A button press sends TEXT button on #homeButton. Receiving that tag toggles the LED independently of the text. Two boards in the same home group can exchange button events. For independent groups, change the tag on both the sender and receiver.
Confirm ready, RX, and physical output separately. The active-low onboard LED differs from an active-high external LED circuit.
