Any application/plugin for this?

 

For example i want my unraid to shut down totally at a specific time.

 

Shut down means total shut down, not sleep/hibernate

Is there such a plugin?

I want to save more and thought hey, i rarely use it at night. So is there?

Btw, forgot to mention automatically 

Btw, forgot to mention automatically 

install the powerdown add-on.  Then issue the following command

echo "/sbin/powerdown" | at 2300

 

It will schedule the powerdown command to run at 2300. 

 

There are many way to make this smarted... if you do a search in the forum you'll see scripts that will shut down on inactivity.
