# Physical Systems (Pi's + other hardware)

## Raspberry Pi systems

All accessible via Tailscale. Use `localuser` (passwordless sudo to root)
except where noted.

| Name | Tailscale IP | LAN IP | Access | Purpose |
|------|-------------|--------|--------|---------|
| pfvsvrpi | 100.91.151.113 | 192.168.1.230 | `localuser` | Server Pi (general purpose) |
| subopi-dev-3 | 100.64.231.65 | 192.168.1.232 | via subodev jump | Suborbital dev Pi 3 |
| subopi-dev-4 | 100.65.224.85 | 192.168.1.231 | via subodev jump | Suborbital dev Pi 4 |

> **Note from operator:** "use subodev to get into subopi-*" — subodev is
> a jump host for the suborbital Pi's.

## 192.168.3.12-24 range

These 13 hosts respond to ping but have no SSH/SNMP. Likely:
- IoT devices
- Cameras
- Phones (VoIP)
- Other DHCP clients

## UniFi Access Points

| AP | Port (core-sw01) | Model | FW |
|----|-----------------|-------|-----|
| UAP-AC-LR | g9 (2902 inErrors!) | UAP-AC-LR | 6.8.2.15592 |
| UAP-AC-Lite | g38 (590 inErrors!) | UAP-AC-Lite | (unknown) |

Both managed by UniFi controller (likely on Home Assistant VM 100 or
pfv-stor1). UniPoller exports metrics to Prometheus.
