Shutdown_Monitor for ASL3 mobile installation

Good Afternoon,

I have just transitioned a mobile node from HamVOIP to ASL3. It has a shutdown module that worked by adding the following: SHUTDOWN_MONITOR="enabled" in /usr/local/etc/allstar.env in HamVOIP.

I am not finding this to work the same. Is this option available in ASL3? If supported, does it need to enabled in a different way?

Thank you in advance,

What did this SHUTDOWN_MONITOR do?

Looks like it's just a simple script that watches some GPIO to use as a shutdown trigger.
