@fenderman86

then it would fire up the server even if the power were not restored yet?

No, that is not how WOL works. True WOL requires a special WOL network packet to turn on or wake a system. The feature has to be supported in the BIOS of the device, to allow another system on the network to wake it up.

Here is thread where WOL was discussed years ago...

HubAction to make WOL requests

Create a Virtual Switch and set the auto-off to 1 sec (it essentially acts as a momentary switch). Install the app below. Select the Momentary switch you just created. Enter the Mac address (no spaces, dashes or colons) of the device you want to WOL. Now you can add this switch to any automatons you need... eg when I open my office door, the lights come on and my pc wakes from sleep. See link to app code below:
