I use a Mac Mini. When nothing it up, it draws like 7W!
How do you accurately measure how much current a PC is drawing at any given time? Do you have some kind of measurement device inline with the power cord?

Are you a programmer by chance? Some are, and they enjoy it! I know a lot of sysadmins / platform engineer types. A lot of them really enjoy the mix of hardware and software integration challenges.
I don't know any sysadmins who would do this. Task scheduler for Windows or rtcwake for Linux. We try to reduce complexity with existing battle tested tools, not create whatever this is. This is definitely not the easy way.

Ah, you're not a tinkerer!
I guess everyone has to go through it.

I definitely am. But this is a very solved problem. It just adds brittleness to the system. Maintenance for this is going to suck. It's going to break in less than a year because you forgot to set a static IP address, or a Python library changes, or the SD card in the PI gets corrupted, or the jack on it fries, or its cheap PSU died and fries the board, etc. Then you're going to have to try to remember how the damn t…
Bingo, but some people never stop tinkering - their joy is in avoiding the well trod path.

Works good IME, but you have to plug it into the wall first. Sometimes if you plug the appliance in, and then plug the KAW in, it will miscalibrate
Well done. But note: you can grab an ATX control board, or configure the RPi as a USB Gadget to wake the machine via power button or keyboard.
Of course, the RockPi doesn't give you any KVM like functionality, though.

Note: If you're going to use an SBC _only_ for wake up signals, you might want to look into alternatives for the RPi such as the Radxa RockPi S [1]. My home server, for example, runs continuously at 7W, which beats many RPi models. Of course, a Pi to wake things doesn't need that much power and could be an older model, but even then, you'd still be burning "empty Watts". Of course, the RockPi doesn't give you any KVM…
This is particularly common if the NIC is a power hungry 10GbE port.
However, in the particular case I found, the motherboard also disables oower to any usb GigE adapter attached.
The solution I found was to attach a USB hub with (empty) SD slots and integrated GigE port. As SD cards require power to remain mounted, the motherboard did not shutdown power to this adapter and WoL worked.
That's what I was thinking too. My home server consumes like 15 W and is silent. If you get a rack mounted server made for data centers and stick it in a closet so you can't hear it then yes, i guess this approach makes sense.
It’s very easy for even the small things to add up.
