N0RMA

Formerly called Homewatch.

Home counter-surveillance detector for Linux (BlueZ + NetworkManager + iw). Detect-only: no jamming, no spoofing. Run: ./n0rma.sh setup once, then ./n0rma.sh run -> http://127.0.0.1:8777

What's new in 0.4

• Evidence report: n0rma evidence -o report.txt writes a plain-text, tamper-evident report of everything flagged (30 days by default) for police or an advocate. Every log line is hash-chained to the one before it; check a saved file with n0rma evidence --verify report.txt. Send the final CHAIN END line to someone you trust right away. The Android app makes the same format, and each can verify the other's reports.
• Device names: the dashboard and n0rma devices show a name for each device (router DNS or mDNS), and you can set your own: n0rma name <mac> Missy iPhone.
• Dashboard tabs (Status / Nearby / Radar / History), "this is my network" and "I know this device" buttons, and fewer false alerts for virtual bridges and loopback addresses.
• Renamed from Homewatch: the command is n0rma (the old homewatch still works), the PyPI package is n0rma-sec, and existing data is kept.

What was new in 0.2

• Dark, muted, low-glare dashboard (no flashing alerts; every status is word + icon + color) with a Night switch (dim red on black)
• A plain-language banner ("All clear" / "Keeping an eye on something" / "Needs your attention") with a breathing dot and live scan ages, so you can see it is working
• "This is mine" on trackers: your own Tile/AirTag stops flagging and shows as yours
• Sister project: n0rma-android (public, with signed APKs on its Releases page) - same detection on a phone, with tap-to-find, room sweeps and survey exports

Install

pip install n0rma-sec (the command it installs is n0rma) (or from source below). System packages are still needed: sudo apt install ieee-data nmap iw network-manager bluez (the vendor database from ieee-data/nmap is required for camera/drone vendor detection - N0RMA warns at startup if it is missing), then python3 -m venv .venv --system-site-packages && .venv/bin/pip install bleak. Optional RF module: sudo apt install rtl-sdr + an RTL-SDR dongle (24 MHz-1.7 GHz only; not 2.4/5.8 GHz).

Commands

Read this first

• This is not a guarantee of safety. A quiet dashboard means "nothing seen by these radios", not "nothing is there". Blind spots: drones without Remote ID, SD-card-only cameras, cellular/GPS trackers, anything on 2.4/5.8 GHz video.
• Remote ID is unauthenticated. Anyone can broadcast a fake one, so a red drone alert means a broadcast claims a drone. Position and operator location are whatever the sender says. Operator coordinates are shown live and are never written to disk; events are pruned after 30 days.
• Do not interfere with a drone (shooting at, jamming or spoofing one is a federal crime). Report it to law enforcement or the FAA.
• The radar is a rough estimate. Signal strength gives only a crude distance, badly distorted indoors, and no direction.
• If you find something: don't touch or move it, photograph it where it is, note the time, and contact local law enforcement. A tracker you don't own: Apple/Android show unknown-tracker alerts and can help identify it.
• --lan is plain HTTP. Anyone sniffing your Wi-Fi can see the private link/token. Use it only on a network you trust. Localhost mode only accepts Host: 127.0.0.1/localhost (blocks DNS rebinding) and state-changing requests need an X-Homewatch header.
• Your Wi-Fi name, home position, tokens and the ntfy topic live in ~/.local/share/n0rma/config.json (mode 600), never in the code.
