Oha

Around 5kWh/day.

My Biggest Power drain is my homeserver/hypervisor/nas/whatever (5600G, 64gb ram, 9xHDD) which uses around 3.5kWh.
Wifi is provided by 2x Extreme Networks WS-AP3825i and 2x Ubiquiti UniFi 6 Plus which total to around 660W/h.
My Router is a small dual-nic shuttle pc with a Pentium G4560 drawing like 310W/h
Switching is done by an Aruba 2930F-24G-4SFP+ Switch that consumes 490W/h

I could probably squeeze out a few more watts if I replace the HDD’s with higher density ones and virtualise my router but I really dont feel like doing that right now…

Yea, I host a few (semi-)public services

Every Service is in its own VM and everything thats publicly accessible sits in its own network sepperated from everything else. I do daily backups in case anything goes wrong

You dont need to map ip+port, most selfhosted services let you change their port to the default http port
