Internet indicator LED

It is possible to place a data or Internet indicator LED in the osmc. I have occupied the 3v for use of a remote control.

Well first you need to tell us which device you use (while I assume you use a Raspberry based on what you write).

If that is the case I am not sure what you mean with “occupied the 3v” because the voltage line can be used multiple times (and actually you have 2) as the control would via one of the GPIO pins.
