# Garmin Connect Health Data Skill

Fetch comprehensive health & fitness data from Garmin Connect for your AI agent.

## Data Coverage

| Category | Fields |
|----------|--------|
| **Activity** | Steps, distance, calories (active + BMR), floors, intensity minutes |
| **Heart Rate** | Min/max/resting heart rate |
| **Sleep** | Duration, score, deep/light/REM/awake breakdown, stress during sleep |
| **HRV** | Last night avg, 5min peak, weekly avg, status (balanced/unbalanced), baseline |
| **Body Battery** | Current level, daily min/max |
| **SpO2** | Average and minimum blood oxygen |
| **Respiration** | Waking and sleep breathing rate |
| **Stress** | Average/max, rest/low/medium/high duration breakdown |
| **Training Status** | Overreaching/Highly Active/Productive/Maintaining/Recovery/Detraining + acute/chronic load ratio |
| **Training Readiness** | Score (0-100) |
| **Fitness Metrics** | VO2 Max, fitness age, endurance score, hill score |
| **Race Predictions** | 5K/10K/Half/Marathon predicted times |
| **Weight/Body Comp** | Weight (kg), body fat %, BMI (requires Garmin Index scale) |
| **Hydration** | Intake (ml) vs goal |
| **Activities** | Individual workouts with HR, duration, calories, elevation, training effect, and detail JSON |
| **Weekly Summary** | Total/avg steps for the week |
| **SQLite Tables** | `daily_summary`, `activities`, and `activity_sets` for queryable local analysis |

## Setup

### 1. Install dependency
```bash
pip install "garminconnect>=0.3.11"
```

### 2. Set credentials (choose one method)

**Option A -- Environment variables:**
```bash
export GARMIN_EMAIL="you@example.com"
export GARMIN_PASSWORD="yourpassword"
```

**Option B -- CLI args:**
```bash
python3 garmin_health.py --email you@example.com --password yourpassword
```

**Option C -- macOS Keychain:**
```bash
security add-generic-password -a "you@example.com" -s "garmin_connect" -w "yourpassword"
```

**Option D -- Credentials file:**
```bash
echo -e "email=you@example.com\npassword=yourpassword" > ~/.garmin_credentials
chmod 600 ~/.garmin_credentials
```

### 3. Set region (China accounts only)

If your Garmin account was registered in China, add this to your shell profile (`~/.zshrc` / `~/.bashrc`) **once**:

```bash
export GARMIN_IS_CN=true
```

This tells the skill to use `connect.garmin.com.cn` instead of the global endpoint -- more reliable for mainland China IPs and prevents 429 rate-limit errors. Skip this step if you have a global Garmin account.

### 4. First run
First login may require MFA verification. You'll be prompted to enter a code sent to your email.

`garminconnect 0.3.x` uses native authentication and cannot reuse legacy Garth token files. Upgrading from `0.2.x` requires one new interactive login and MFA challenge.

### 5. Use with OpenClaw
Ask your AI agent:
- "Show my health data"
- "How did I sleep last night?"
- "What's my HRV?"
- "Am I overtraining?"

## Usage

```bash
# Fetch today's data (default)
python3 garmin_health.py

# Fetch specific date
python3 garmin_health.py --date 2026-03-16

# Show latest cached data
python3 garmin_health.py --show

# Use Garmin Connect CN endpoint (Chinese accounts / mainland China IP)
python3 garmin_health.py --cn

# With credentials
python3 garmin_health.py --email you@example.com --password pass
```

## Data Storage

- `~/.garmin_health/YYYY-MM-DD.json` -- Daily JSON snapshots
- `~/.garmin_health/latest.json` -- Most recent JSON snapshot
- `~/.garmin_health/garmin.db` -- SQLite database with `daily_summary`, `activities`, and `activity_sets` tables
- `~/.garminconnect/` -- OAuth token cache

Override with env vars:
- `GARMIN_DATA_DIR` -- Change data directory
- `GARMIN_TOKENSTORE` -- Change token cache directory
- `GARMIN_IS_CN=true` -- Use Garmin Connect CN endpoint (set once in shell profile)

## Supported Languages

All labels and output in English. JSON field names are English by design.

## Security & Privacy

- **Your credentials only** -- this skill authenticates with Garmin Connect using your own account credentials. No credentials are shared with or stored by this skill.
- **Local storage only** -- all fetched health data is saved as JSON/SQLite files on your own machine. No data is sent to any third party.
- **Token caching** -- after first login, an OAuth token is cached locally (`~/.garminconnect/`). Subsequent runs reuse this token and do not re-send your password.
- **Recommended auth** -- use macOS Keychain or environment variables rather than `--password` CLI flag to avoid password exposure in shell history.
- **Official API only** -- all requests go directly to `connect.garmin.com` (or `connect.garmin.com.cn` for CN accounts). No proxies or intermediaries.

## Requirements

- Python 3.10+
- `garminconnect >= 0.3.11`
- A Garmin Connect account
- Device: Any Garmin watch/fitness tracker synced to Garmin Connect
