PSU plugin Question

Hi, I have the latest Octoprint and the PSU plugin with a relay off of a GPIO pin on the Pi. All works by the lightning button fine. Is there a way to have Octoprint turn off the printer when the print is done. I've seen suggestions that it can with a smart plug, but I'm just using a relay from the Pi.

Thank you

It should work with the power off option

My options are different from yours. I have the latest Octoprint and 0.1.10 of the PSU plugin. Don't have psu on command or psu off command Also my general is only board or gpio? Here is a screen shot, hope it's not too small to see. Capture|306x500
Thank you

I also wasn't sure how to put a photo up here.

I finally got this working with the experimental command.
