What is unifi-whos-home?

A guide for diagnosing one misbehaving device on a UniFi network, whether it uses WiFi or a cable. It checks the device's connection, signal quality, roaming history, blocking status, and route through the network.

Use it when a device is slow, disconnects, cannot connect, cannot reach the internet, or has roaming problems.

It replaces guesswork with checks that distinguish a weak wireless signal, blocked access, roaming trouble, or another network problem. A client means any connected device, such as a phone, laptop, or camera.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00746
Opus 5.5	$0.00000	$0.00298
Sonnet 5.5	$0.00000	$0.00149
Haiku 4.5	$0.00000	$0.00075

Security

Grade A, and why

unifi-whos-home scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UniFi Who's Home

Friendly inventory of everything connected to the network, translated into everyday language — plus careful handling of genuinely unknown devices.

Key knowledge

Randomized MACs are normal: modern phones/laptops use a different fake MAC per WiFi network and often lack hostnames. A phone can appear as "Unknown (Apple)" — that is not an intruder.
OUI tells you the maker: the start of a MAC identifies the manufacturer (the client oui field). Translate: Apple→iPhone/Mac, Samsung→TV/phone, Sonos→speaker, Raspberry-Pi/Proxmox→homelab box, etc.
Infra devices must never be blocked: APs, switches, NAS, DNS servers. Cross-check candidates against list_devices (your actual hardware) before proposing any block.

Workflow

Inventory — list_clients (connected now); group as:
- Your equipment (matches list_devices)
- Recognizable family stuff (named or obvious OUI: phones, TVs, printers)
- Unknown — list separately with every clue: maker (oui), name/hostname, connection type, first/last seen.
Translate each unknown: "Unknown 'bc:24:11…' = a virtual machine on your Proxmox server", "Unknown 'Apple' = someone's iPhone using private-address mode".
Suspicion checklist (only flag if several hold):
- wireless + unknown maker + active right now + nobody recognizes it
- appeared between dates the user can place
- NOT seen on wired ports
For each unknown, ask the owner-in-the-house: "do you own a [maker] device?"
- Yes → suggest naming it in the UniFi app so future audits are clean.
- No / unsure → offer block_client AFTER stating plainly what blocking does ("it will be kicked off and unable to rejoin until we allow it back") and get explicit confirmation.
Reassure with facts: WPA2/WPA3 means strangers can't join without the password; unknown entries are usually family gadgets with privacy features.

Output format

Who's home right now: [N devices]
🏠 Your gear: [count] · 👪 Recognized: [count] · ❓ Unknown: [count]

❓ Unknown devices:
1. [maker/OS guess] — [name] — [where seen] — [first seen date]
   Likely is: [best plain-English guess]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
