Yes depending on the sleep state. Also some power is going to ram to keep it alive. I think for framework it's in the realm of 5% an hour or something like that.
I usually go the hibernation route.
Desktops I sleep to ram, laptops I hibernate to the SSD.
I use unifi for wifi because honestly I like the dashboard.
But.. for anything layer 3, I'm using MikroTik. It's extremely powerful without actually running your own router, and many are Poe as well. I'm running a RB5009 which is overkill for me.
I chose RB5009 because it runs DoH, ZeroTier, sub interfaces, it's rack mountable, passively cooled, poe capable, and can handle up to 2.5gb symmetrical. I just wish they had 2 x SFPs so I can use a full 10gb WAN
PiHole and then Minecraft actually all through CLI.
Imagine my shock once I found out about screen and SSH. I didn't need to walk back and forth between my computer and the server.
I didn't touch a GUI for about 4 years.
