Power Light On Board

ESPHome
1

Hello
I’m new to the ESP32 experience and have a question. Is there normally a LED on when power has been applied to the board? The only way of knowing if the board is working is to look at the Home Assistant dashboard and see if the button’s I’ve programed are active. I’ve included a picture of the board. If the light is to be “on” then how do I make that happen? Thanks in advance for any help that can be provided.

The board should have an onboard led.

It’s controlled by GPIO23. Maybe turn it on at on_boot: in the ESPHome config.

Thanks. Here’s the code I used:

# Define the output pin for the LED
  - platform: gpio
    pin: 23 
    id: output_led

light:
  - platform: binary
    id: light_led
    name: LED
    output: output_led 
    restore_mode: ALWAYS_ON

Presense of LED directly connected to supply power highly depends on manufacturer of board - some have, some not. Can use LED connected to GPIO, but beware - it can activated if/when ESPHome loaded. It is not actually power indicator as You asking.
