This is a remote box to switch 230V with the octoprint/raspberry. So i can turn the Power for my printer on and off by remote. The raspbery Pi normaly needs 5W and the Printer needs 10W stantby. (15W standby together) I had uploadet 2 diverent parts for the body of the case. One version for the K8200 heatbed upgrade (to set on top of the powersupply) and one universal version. Inside the box in a relais modul with 2 relais so i can switch both wires. The switch on the backside can select the mode: "permanent on" / "off" / "raspi controll". It uses WiringPi For installation you will find infos at http://wiringpi.com/download-and-install/ To ad the commands to octopi you must edit the config.yarnl I had upload the file printerPower2.txt with the modifikation under "system:" For wiring you must remove the jumper at the relaisboard.
