The plans/ directory predated the mikado method approach. Deleted all completed and abandoned plans, converted the still-relevant migrate-forgejo-from-brew into a lean mikado chain root card under how-to/forgejo/, cleaned up dangling wiki-links across docs, and fixed a stale "pre-commit" reference to "prek".

# UniFi
|
|
|
|
Home WiFi router and network controller, managed via the UX7 web UI.
|
|
|
|
## Quick Reference
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| **Model** | UniFi Express 7 (UX7) |
|
|
| **LAN IP** | `192.168.1.1` |
|
|
| **Management URL** | `https://192.168.1.1` |
|
|
| **Management** | Web UI only (no IaC) |
|
|
| **Power** | Battery-backed via UPS (see [[power]]) |
|
|
|
|
## What It Does
|
|
|
|
The UX7 is the home WiFi access point and network gateway. It provides:
|
|
|
|
- WiFi (main, guest, IoT networks)
|
|
- DHCP for all network subnets
|
|
- Built-in UniFi controller for managing adopted devices (switches)
|
|
- Zone-based firewall and traffic management
|
|
|
|
## Networks
|
|
|
|
| Network | VLAN | Subnet | Purpose |
|
|
|---------|------|--------|---------|
|
|
| Main | 1 (default) | 192.168.1.0/24 | Trusted devices (indri, sifaka, gilbert, mouse) |
|
|
| Guest | 2 | 192.168.2.0/24 | Visitors, internet-only |
|
|
| IoT | 3 | 192.168.3.0/24 | Smart devices (Frame TV, appliances) |
|
|
|
|
Three-network segmentation configured manually via UX7 web UI (Feb 2026).
|
|
|
|
## Network Topology
|
|
|
|
```
|
|
ISP Modem
|
|
└── UniFi Express 7 [WAN]
|
|
└── [LAN port] ──→ Switch A (by router/sifaka)
|
|
├── sifaka (Synology NAS)
|
|
└── ~12ft Cat6 ──→ Switch B (on desk)
|
|
├── indri (Mac Mini, primary server)
|
|
└── gilbert (USB-C adapter)
|
|
```
|
|
|
|
All wired devices share the default VLAN (192.168.1.0/24). The two daisy-chained UniFi Switch Flex Minis provide enough ports for all devices while using the UX7's single LAN port.

|
|
## Operations
|
|
|
|
| Task | Method |
|
|
|------|--------|
|
|
| Manage networks/WiFi/firewall | `https://192.168.1.1` web UI |
|
|
| Backup configuration | Settings → System → Backup |
|
|
| Restore from backup | Settings → System → Backup → Restore |
|
|
|
|
## Authentication
|
|
|
|
Local admin account on the UX7. Credentials stored in 1Password (vault `blumeops`). WiFi passphrase stored in 1Password item "Radio New Vegas" (Wireless Router type) in vault `blumeops`.
|
|
|
|
## Why Not IaC?
|
|
|
|
Attempted Feb 2026 with the `ubiquiti-community/unifi` Terraform provider via Pulumi. A "no-op" update on the default LAN network reset undeclared properties, bricking the network and requiring a factory reset. The provider ecosystem is too immature for single-device infrastructure.
