Switchmote Green LED with PIR

[Atalonica]

Hello, I saw on the web that middle green LED (of switchmote) can be used for anything when PIR sensor is attached.
But this LED is going to be always ON if the PIR is running, am I correct? Thank you.

You are correct, the D18 (A4) is powering the green LED and the PIR (when present).

Wow that was fast! Thank you. Good way to see if it is active anyway.
