Reset button needs to be press after powering for the ESP32 to boot. #3
If the ESP32 is connected to the board, then when you connect the power supply you need to press the reset button on the ESP32 to make the ESP32 boot.
This is probably link to the one of the 4 GPIO of the relay being pulled down during the boot. I need to investigate which GPIO is producing this behavior and change it in the next release of the board.
