Seems to me that if you want to waste time and money engineering your setup more net efficient, just buy a few solar panels and LiFePo4 batteries to buffer. You can run other stuff off of it, too. I always choose “make more money” over “pinch pennies”.
for ideal I need port knocking for wake up
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.

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-...

Running states around 1W? How?
Earlier quoted context omitted.
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?
You can use "smart" plug such as the Sonoff S31 (flash ESPHome to make it cloud-free).

1W is a unicorn as just plugging in a power supply with no PC parts hooked up will register 1W. <10W is more realistic. Select a PC that can run off a laptop charger. Check manufacturer spec sheets for the idle power consumption. Don't install any PCIe cards or hard drives. Use powertop --autotune.

I’m not sure that is the constraint you think it is.

Only put the RAM you need in the box, use peripherals with working ASPM, attach them to the northbridge PCI ports instead of the CPU's root ports, use wireless instead of wired networking, and don't attach a display.
I do basically all of that, CPU idles around 5% but still consumes over 100W. (Minus the Wireless part) (5800X + 64GB) I can enable Eco Mode in the BIOS, which will bring down the CPU to about 65W max although its still at about 100W total system.

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.
Also 20W is fairly low for idle draw right? Like I think you can get proper machines down that low if you know what to look for but most stuff bigger than a mini PC is gonna be drawing 40+? I might be slightly miscalibrated though. Anyway it's not about the money for me it's any the aesthetics. Burning power for nothing is yucky. Edit: just been Googling around. OP is running one of these HP mini PCs. They are pretty…
