It is a little bit dangerous to let a 3D printer run unattended. 220 degree at the Hotend, a heated printbed, liquid plastic and in my case cheap electrical parts from china... So I wanted to monitor the print process from everywhere and the possibility to shutdown my both printers ... here is my solution ...
If you have only one printer you can use the second plug socket for lighting as example. This construction is also usable as an IPswitch without octoprint, if you want to switch more plugs, you just need more relay and plug sockets ...
If you do not have any experience with electricity, do not do this instructable, a little mistake can be really dangerous ... If you do this instructable, you do it on your own risk !
