Our 3D Inovator got a Rasbperry PI, Octoprint and a light switch. It’s network device finally. 
Looks good. You may end up with problems on that R-Pi if you use the switch to just cut power rather than doing an operating system shut-down. Mine did fine for a while, but then the SD card was corrupted after a hard shut-down.
Possible Solution: Leave the R-Pi on when you shut everything else off. R-Pi draws very little current.
Or configure OctoPrint to support shutdown from its interface and use that before switching off the power: https://github.com/foosel/OctoPrint/wiki/Cookbook:-System-Commands#wiki-shutdown-the-server-linux
You might be able to hook the switch to a set of gpio pins and set it to shut down when you flip the switch. Just an idea. I have not done much with my gpio pins yet.
Thanks for the solutions! I’m aware of the SD card problems when powering off so I’m shutting down manually for now. It’s v1 upgrade. 
I’ll try Gina’s Octoprint sw solution first. It seems the easiest way.
