 Unfortunately, it does not allow me to turn on the printers power supply using the Raspberry Pi.
 But it is possible to do that via the [OctoPrint REST API](https://docs.octoprint.org/en/master/api/index.html).
 Because of that, I wrote a small tool to trigger the power of my printers that lives in the system tray.
-It runs on Linux using the Python Qt5 bindings.
+It runs on Linux using the Python Qt5 bindings, but without much work it should be able to run on other platforms with PyQt5 as well.

-You need to enter the hostnames / IPs and the API keys of your printers at the beginning of the python file in the repo.
-The program will automatically detect if you are using the [PSU Control OctoPrint Plugin](https://plugins.octoprint.org/plugins/psucontrol/) it will use that to toggle the power.

 Otherwise it looks for custom system commands, named "all on" and "all off", as described in the [OctoPrint docs](https://docs.octoprint.org/en/master/configuration/config_yaml.html#system).
