I would be tempted to try using the Pi as a router & firewall with the server on another subnet, having it wake the server using traditional WOL as needed. That feels simpler to me and more controlled. But my overall feeling is that not much power is saved here overall compared to a well set up server. Good project though quite educational.

#12All this complexity to save a few bucks per year on your electricity bill? This is ridiculous, the Pi costs far more than what you can be expected to save.

#15Have you measured the power consumption of your "high power consumption" server?
Seriously. You can get running states around 1W these days.
What to do about this? https://forums.developer.nvidia.com/t/phantom-rtx-5090-high-...

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.

In many European countries electricity is quite expensive. In the U.K. for example, running 20 watts nonstop for a year will cost you around $65 on a typical tariff. If you have more than one home server the savings can quickly add up.

My home server setup when running at full tilt consumes approx 160 watts iirc.
I'd love it if I could turn off my systems for when I really need them.
