Tracking PetTracer pet location

Why this exists

PetTracer exposes an (unofficial) web portal API used by their apps/website. This skill gives a reliable, low-drama workflow for:

• Current location (latest known point)
• Recent route/history (time-windowed points)
• Near-real-time updates (WebSocket push, optional)

It is designed to minimise API load (be respectful) and to produce consistent, copy/paste-friendly outputs.

Quick start

Snapshot location (recommended default)

1. Set credentials (prefer env vars, not CLI args):

export PETTRACER_USERNAME="you@example.com"
export PETTRACER_PASSWORD="••••••••"

2. List devices:

python scripts/pettracer_cli.py list --format json --pretty

3. Locate a pet:

• By name:

python scripts/pettracer_cli.py locate --pet "Fluffy" --format json --pretty

• By id:

python scripts/pettracer_cli.py locate --device-id 12345 --format json --pretty

• If the account has exactly one collar, you can omit --pet/--device-id:

python scripts/pettracer_cli.py locate --format json --pretty

Get location history (last 6 hours)

python scripts/pettracer_cli.py history --pet "Fluffy" --hours 6 --format json --pretty

Core workflow the agent should follow

1) Decide: snapshot vs history vs live updates

• Snapshot: user asks “where is X right now?” → use locate.
• History: user asks “where has X been today/last hour?” → use history.
• Live: user wants continuous updates → use WebSocket (see references/websocket.md).

Default to snapshot unless the user explicitly wants a route or live tracking.

2) Authenticate safely

Preferred order:

1. Use PETTRACER_TOKEN if already available.
2. Else login with PETTRACER_USERNAME + PETTRACER_PASSWORD (or PETTRACER_EMAIL).

Never ask the user to paste tokens into chat. Ask them to set env vars or store secrets in their vault.

Optional overrides (useful for debugging / future-proofing):

• PETTRACER_API_BASE (REST base; default https://portal.pettracer.com/api)
• PETTRACER_WS_BASE (WebSocket base; default wss://pt.pettracer.com/sc)

3) Identify the right device

• Fetch devices via GET /api/map/getccs (wrapped by pettracer_cli.py list).
• Match by details.name case-insensitively.
• If multiple matches: show a disambiguation list (id + name) and ask the user which one.
• If no match: show available device names.
• If the account has exactly one collar, you can default to it.

4) Fetch location data

• Current location comes from device.lastPos (collars) or top-level posLat/posLong (HomeStations):
  • posLat, posLong
  • timeMeasure (timestamp)
  • acc (accuracy, metres) or horiPrec (fallback)
• History uses POST /api/map/getccpositions with:
  • devId, filterTime (ms), toTime (ms)

See references/endpoints.md and references/data-model.md.

5) Present results consistently

When reporting location, include:

• Pet name + device id
• Coordinates (lat, lon)
• Last update time
• Accuracy (if present)
• How old the fix is (seconds/minutes since last fix), if possible
• Optional: a map link (Google Maps + OpenStreetMap)

Preferred JSON shape (for tool-to-tool handoff):

{
  "pet": { "id": 12345, "name": "Fluffy" },
  "last_fix": {
    "lat": 48.137154,
    "lon": 11.576124,
    "time": "2026-02-25T12:34:56+00:00",
    "accuracy_m": 12
  },
  "last_fix_age_s": 90,
  "battery_mv": 4012,
  "battery_percent_est": 78,
  "home": false,
  "links": {
    "google_maps": "https://www.google.com/maps?q=48.137154,11.576124",
    "openstreetmap": "https://www.openstreetmap.org/?mlat=48.137154&mlon=11.576124#map=18/48.137154/11.576124"
  }
}

Notes:

• battery_percent_est is an estimate derived from voltage (PetTracer reports millivolts, not %).
• If there’s no GPS fix, report error=no_recent_fix and include last_contact.

Live tracking (optional, avoid aggressive polling)

If you need frequent updates:

• Prefer WebSocket push (avoid aggressive polling).
• Only fall back to polling if WebSocket is not possible; keep polling ≥ 60s by default.

Install dependency:

pip install aiohttp

Then run:

python scripts/pettracer_watch.py --pet "Fluffy"

See:

• references/websocket.md
• scripts/pettracer_watch.py for a working SockJS/STOMP implementation.

Troubleshooting playbook

No location / lastPos is missing

Common reasons:

• Collar hasn’t reported a GPS fix recently (indoors, low signal).
• Battery low / collar off.
• Subscription expired.

Action:

• Report “no recent fix” and show lastContact if available.
• Suggest switching to a higher-frequency mode (Fast/Live) in the PetTracer app/portal only if the user asks (see references/modes.md).

Auth failures (401 / invalid_auth)

• Re-login to obtain a fresh access_token.
• Confirm the login payload uses keys login + password (not username).

Rate limiting / service respect

• Avoid tight loops against /map/getccs.
• Prefer WebSocket for near-real-time tracking.

THE EXACT PROMPT — Location response format

Use this when the user wants a human-readable answer:

Give the pet’s latest known PetTracer location.

Include:
- Pet name + device id
- Time of last fix (and last contact if different)
- Coordinates + map link(s)
- Accuracy (metres) if present
- One-line assessment: “recent fix” vs “stale fix” (use last_fix_age_s if available; interpret in the context of the current tracking mode)
