If Something Happens to Ben#
This document is written for you — not for a technical audience. It explains what all the computers and equipment in the house actually do, what matters for your day-to-day life, what you can safely ignore, and what to do if you want to simplify or shut things down.
Ben has friends who understand this system technically. This document is about helping you understand it at a level where you can make decisions and ask the right questions.
The Short Version#
Most of the computer equipment in the house runs automatically and doesn’t need attention. The things that actually affect your daily life are:
- The internet and Wi-Fi — managed by a device called Yukari
- The smart home — lights, automations, managed by Home Assistant
- The media server — Jellyfin, for watching movies and shows
- The NAS (file storage) — a device called Voile, where files and backups live
Everything else is Ben’s hobby server infrastructure. It won’t affect you if it goes down, and it can be shut off.
What Each Device Is#
Yukari — The Router (Critical)#
Yukari is the Unifi Dream Machine Pro — it’s the router and Wi-Fi controller for the house. This is what gives everything internet access.
You need this. If it breaks, call your internet provider and/or ask a technical friend.
Wi-Fi networks: - FalseBlue — main home Wi-Fi. Uses your email/domain credentials to log in (enterprise auth) - FalseBlue-Basic — backup Wi-Fi with a regular password. Password is stored in Bitwarden (Ben’s personal vault) - FalseBlue-Guest — guest Wi-Fi. This is a captive portal - FalseBlue-IoT — for smart home devices. Password is in Bitwarden (Ben’s personal vault)
If FalseBlue stops working, connect to FalseBlue-Basic — it uses a regular password and bypasses the enterprise login.
Voile — The NAS / File Server (Important)#
Voile is a Synology NAS (Network Attached Storage) — basically a box with hard drives in it that stores files and runs several services. It’s always on.
Admin panel: https://voile:5001 or https://192.168.0.25:5001
It hosts:
- File backups for all the computers in the house
- The backup manager (BorgWarehouse) — keeps copies of everything
- Gitea (Ben’s private code backup server)
- TaskWarrior (task management)
- Some of the media library storage
If Voile breaks: The day-to-day internet still works. You’d lose access to some locally hosted services and file backups. Ask a technical friend to help assess whether drives need replacing. The Synology admin panel has a built-in health dashboard that will tell you if a drive has failed.
Home Assistant — Smart Home (Important for Daily Life)#
Home Assistant runs on the home server (Ereshkigal) as its own virtual machine. You reach it in a web browser at the address below.
Login: http://192.168.0.55:8123
It controls: - The smart lights and switches - The succulent grow light (turns on at sunrise, off 10 hours later) - The side door light (turns on when it’s dark and you get home) - Low battery alerts for smart devices - AdGuard — the ad and tracker blocker for the whole network (runs inside Home Assistant, on the home server)
If Home Assistant goes down: The lights can still be controlled manually from their physical switches. The automations just won’t run. Home Assistant lives on the home server now, so there’s no box to unplug — restarting it is a job for a technical helper (see the Home Assistant VM runbook). It rarely needs attention.
Ereshkigal — The Big Server (You Can Shut It Off)#
Ereshkigal is a large rack-mounted Dell server. It runs: - Jellyfin (the media/streaming server) - The Nix binary cache (speeds up Ben’s builds) - Various monitoring services
This machine is loud, uses significant electricity, and is entirely optional for your day-to-day life.
If you want to turn it off: it’s safe to power it down. You’ll lose access to Jellyfin and the acquisition services, but nothing critical to the house depends on it.
If you want to keep Jellyfin: A technical friend can help migrate Jellyfin to a simpler setup (like a Plex or Jellyfin server running on Voile, or a streaming subscription).
Mokou — Ben’s Desktop#
Ben’s main desktop computer. If you don’t use it, you can leave it off. Nothing critical runs on it permanently.
The document-tagging and chat AI tools on the big server (Ereshkigal) normally run on Ben’s work laptop, and Mokou is only the automatic backup for them. Turning Mokou off is fine — those AI features keep working unless the work laptop is also gone, and nothing that affects daily home life depends on them either way.
Shinobu — Ben’s Laptop#
ThinkPad P14s. Personal/Business laptop, nothing server-related.
Razer — Old Laptop#
Older Razer Blade laptop. Nothing critical. Can be set aside or sold.
Octopi — Raspberry Pi (3D Printer Controller)#
Small Raspberry Pi connected to the 3D printer. If you don’t use the printer, you can unplug it. Nothing else depends on it.
Myon — Rented Cloud Server (Paid Monthly)#
Myon is not in the house — it’s a small cloud server Ben pays for monthly (rented from a company called BuyVM, located in Las Vegas). The file-download system on the big server routes its traffic through it.
Nothing in the house breaks when it’s off — the download system just stops working until it’s back.
If the servers are being shut down permanently, this subscription should be cancelled so it doesn’t keep billing every month. A technical friend can help find the BuyVM account and cancel it.
Services You Might Actually Use#
Jellyfin — Streaming#
Jellyfin is like a private Netflix for movies, TV shows, anime, and music that Ben has collected. It runs on Ereshkigal.
Access: watch.inaba.network (from anywhere, family
account sign-in) or http://ereshkigal:8096 (on the home network). Music,
audiobooks, and ebooks have their own sites — see
Movies, Music & Books.
If Ereshkigal is turned off, Jellyfin is unavailable. Netflix, Disney+, or other subscriptions are straightforward replacements.
The Media Library#
Movies, TV shows, books, and music are stored on Voile. If you want to keep any of this, a technical friend can help you copy it to an external drive before shutting down the servers.
If Something Breaks#
Wi-Fi is down#
- Check that Yukari (the router) has power and lights on
- Try connecting to FalseBlue-Basic instead (password in Ben’s Bitwarden)
- Try rebooting Yukari by unplugging it for 30 seconds
- If still broken, call your ISP or ask a technical friend
Lights / Home Assistant not working#
- Physical switches still work manually
- Try accessing http://192.168.0.55:8123 to see if the HA panel is up
- If the HA box is unresponsive, unplug and replug it
- If it still won’t come back, ask a technical friend — restoring HA is straightforward
A server makes alarming noises or smells#
- Power it off at the power strip
- Don’t try to diagnose hardware yourself — call a technical friend
Something is backed up and you need a file#
Backups for all the NixOS machines are stored on Voile via BorgWarehouse. A technical friend can retrieve specific files. The restore procedure is documented in Restoring a Host from Backup.
Who to Ask for Help#
Ben has friends who understand this system. They have access to the code and documentation. Point them to this repository:
GitHub: https://github.com/tsunaminoai/nix-flake-final
The full technical documentation is in pkgs/docs/. For emergencies, the most useful docs are:
The friends who can help don’t need to understand all of it — this documentation is meant to make that recovery as straightforward as possible.
If You Want to Simplify or Shut Everything Down#
It’s okay to want a simpler setup. Here’s what to keep, what to let go, and what to replace:
| Thing | Keep? | Simple replacement |
|---|---|---|
| Internet / Wi-Fi (Yukari) | Yes | It’s just a router — keep it |
| File backups (Voile) | Recommended | External drive backups, or iCloud/Backblaze |
| Smart home (Home Assistant) | Optional | Most smart devices work with Apple Home or Google Home |
| Media server (Jellyfin, Ereshkigal) | Optional | Netflix, Plex, Disney+, etc. |
| Ad blocker (AdGuard in Home Assistant) | Optional | Browser extension (uBlock Origin) |
| NixOS on the laptops | Optional | A technical friend can reinstall Windows or macOS |
| The big server (Ereshkigal) | No need to keep | Can be powered off or sold |
Steps to wind down gracefully#
- Ask a technical friend to export any files you want from Voile (photos, documents, media)
- Copy media to an external drive if you want to keep it
- Export Home Assistant configuration if you want to recreate automations elsewhere
- Power down Ereshkigal — unplug from the wall
- Leave Voile and Yukari on as long as you’re in the house — they’re the core of home networking and storage
- Voile can eventually be factory-reset or sold; Yukari can be replaced with any standard router
You don’t have to do any of this at once. The house works fine with Ereshkigal off and everything else left alone.
