  • Pi 4 should be plenty to run Jellyfin, homeassistant, pihole and octoprint. Docker setup is pretty straightforward, and I can vouch that HA & pihole containers work great on RPi, if you want to leave the Jellyfin setup as-is and put the others alongside.

    If you’re looking for an excuse to expand, my vote is for an N100 type system. I got one with 4 ethernet ports, PCIe for a wifi card, couple of NVME slots, and a half dozen SATA ports for $100-150. That’s a huge step up in potential without much increase in power draw. With the right wifi card, you can even use it to replace your WAP/router.






  • I’ve used a retired desktop for my home server since 1999. It doesn’t have the fancy web-UI management of commercial NAS, but I’m comfortable with command line and config files.

    At some point, I realized I could use its wifi card and hostapd to replace my WAP. That was a bit of an adventure initially finding a card that really supports AP mode and setting up hostapd, but has now allowed me to migrate from 802.11g to n to ac much cheaper than buying whole new devices,

    Recently converted to an N100 with 4x ethernet ports, which let me unplug my little 5-port switch.

    Managing this doesn’t feel like a second job: it’s stable and just works. Automatic updates, with kernel blacklisted; periodically log in, update kernel & reboot. It does give me the opportunity, when I get inspired, for a weekend project, like adding hostapd or a new service, either via docker or bare metal. I like that I have one device doing “NAS,” WAP, and router jobs.



  • This is one of my pet peeves with containerized services, like why would I want to run three or four instances of mariadb? I get it, from the perspective of the packagers, who want a ‘just works’ solution to distribute, but if I’m trying to run simple services on a 4 GB RPi or a 2 GB VPS, then replicating dbs makes a difference. It took a while, but I did, eventually, get those dockers configured to use a single db backend, but I feel like that completely negated the ‘easy to set up and maintain’ rationale for containers.





  • I switched from an I3-530, nominal TDP 73W, to an N-100, nominal TDP 7W, and power from the wall didn’t change at all. Even the i3 ran around 0.1 CPU load, except when transcoding, and I’m left with the impression that most of the power goes into HDDs, RAM, maybe fans, and PS losses. My sense is that the best way to decrease homelab power use is to minimize the number of devices. Start with your seyrver at 60W, add a WAP at 10-15W, maybe a switch at 10-15W… Not because of the CPUs, necessarily, but because every CPU every CPU comes with systems to keep the CPU going, keep the power regulated, etc.





  • My ISP seems to use just normal DHCP for assigning addresses and honors re-use requests. The only times my IP addresses have changed has been I’ve changed the MAC or UUID that connects. I’ve been off-line for a week, come back, and been given the same address. Both IPv4 and v6.

    If one really wants their home systems to be publicly accessible, it’s easy enough to get a cheap vanity domain and point it at whatever address. rDNS won’t work, which would probably interfere with email, but most services don’t really need it. It’s a bit more complicated to detect when your IP changes and script a DNS update, but certainly do-able, if (like OP) one is hell bent on avoiding any off-site hardware.
