What do you plan on doing with the FPIOs?

Automatically fire up the kettle whilst you wait for the bed to heat up?

Don't forget to put a max amps label on it so nobody forgets there's only a 10A relay controlling that 15A outlet. That may rule out using it for the coffeemaker too.

Im going N.O. on the config so someone would have to actually log into my RaspberryPI and switch it on for it to pass current.

ok so here is the finished box, plugged in and tested with a desk lamp. i can now control all 4 plugs by just a click of the mouse via octopi

I also used GPIOs on RPI2, and added corresponding controls in Octoprint, in order to turn on/off both the printer and the lights in my enclosure, directly from octoprint interface.

Difference is that in order to turn on/off the printer, my relay is connected to the very same wire as the on/off switch. (I have a V1, with a PC power supply, I don't know about other versions).
I found a way to put 2 connectors there, and depending which one connector I use to plug the relay, my relay comes either in parallel or serial with the switch.

This way I either need to have both relay and switch on to turn the printer on, or only one of them two.
