How can I add an icon to the Windows desktop to switch off/switch on/toggle the outlet?

Create a shortcut, select an icon and assign a command to invoke cURL with parameters to access the correct URL (see URL API).  The AN19 example shows how to control the output (electrical socket) by accessing a particular URL. Use the example that invokes cURL and assign this invocation to the icon on the desktop.

Ask for a price or technical parameters
