KC868-A16 ESPHome led output not working

[stanchiam]

Hi,

I tried turning on and off without any problem, esphome is working.
But when i check the board, the output led does not light up when i turn it on.
Below are the yaml i used, is there anything missing or wrong that causes the led not to light up when i switch it on using esphome?
Btw i have not connect or use any DC12/24v input yet.

Ops, connecting 12v DC Input by looping from the power, the led light up
