Garmin Connect Skill

Query Garmin Connect health data by writing UV inline Python scripts using garminconnect.

Setup

Credentials

Requires GARMIN_EMAIL and GARMIN_PASSWORD in workspace/.env.

If not set, ask the user for their Garmin email and password, then append to .env:

echo 'GARMIN_EMAIL=their_email' >> .env
echo 'GARMIN_PASSWORD=their_password' >> .env

Consider using app-specific passwords if the user has 2FA enabled.

Authentication

Once credentials are in .env, authenticate and save the session:

set -a; source .env 2>/dev/null; set +a; uv run - <<'EOF'
# /// script
# requires-python = ">=3.11"
# dependencies = ["garminconnect>=0.2.38"]
# ///
import os
from pathlib import Path
from garminconnect import Garmin

client = Garmin(os.environ["GARMIN_EMAIL"], os.environ["GARMIN_PASSWORD"], return_on_mfa=True)
result1, result2 = client.login()

if result1 == "needs_mfa":
    print("MFA_REQUIRED")
else:
    client.garth.dump("garmin-session")
    Path("garmin-session").chmod(0o700)
    print(f"SUCCESS: Logged in as {client.get_full_name()}")
EOF

If the output contains MFA_REQUIRED, ask the user for their MFA code, then run:

set -a; source .env 2>/dev/null; set +a; uv run - MFA_CODE_HERE <<'EOF'
# /// script
# requires-python = ">=3.11"
# dependencies = ["garminconnect>=0.2.38"]
# ///
import os, sys
from pathlib import Path
from garminconnect import Garmin

client = Garmin(os.environ["GARMIN_EMAIL"], os.environ["GARMIN_PASSWORD"], return_on_mfa=True)
result1, result2 = client.login()
client.resume_login(result2, sys.argv[1])

client.garth.dump("garmin-session")
Path("garmin-session").chmod(0o700)
print(f"SUCCESS: Logged in as {client.get_full_name()}")
EOF

Session is saved to workspace/garmin-session/ and lasts ~1 year.

Query Template

set -a; source .env 2>/dev/null; set +a; uv run - <<'EOF'
# /// script
# requires-python = ">=3.11"
# dependencies = ["garminconnect>=0.2.38"]
# ///
from datetime import date, timedelta
from pathlib import Path
from garminconnect import Garmin

TOKEN_DIR = Path("garmin-session")
if not TOKEN_DIR.exists():
    print("ERROR: Not authenticated — run Garmin setup first")
    exit(1)

client = Garmin()
client.login(str(TOKEN_DIR))

today = date.today().isoformat()

# === YOUR QUERY CODE HERE ===
stats = client.get_stats(today)
print(f"Steps: {stats.get('totalSteps', 0):,}")
EOF

API Reference

Health Methods

Activity Methods

Note: All dates use "YYYY-MM-DD" string format.

Key Fields

get_stats(): totalSteps, totalDistanceMeters, totalKilocalories, activeKilocalories, floorsAscended, restingHeartRate, minHeartRate, maxHeartRate, averageStressLevel, maxStressLevel, lowStressDuration, mediumStressDuration, highStressDuration, restStressDuration, bodyBatteryChargedValue, bodyBatteryDrainedValue

get_sleep_data(): Access via data.get("dailySleepDTO", {}): sleepTimeSeconds, deepSleepSeconds, lightSleepSeconds, remSleepSeconds, awakeSleepSeconds. Scores via dailySleepDTO.sleepScores.overall.value

get_hrv_data(): weeklyAvg, lastNightAvg, lastNight5MinHigh, status, baseline.balancedLow, baseline.balancedUpper

get_activities(): activityId, activityName, activityType.typeKey, startTimeLocal, duration, distance, calories, averageHR, maxHR, elevationGain, averageSpeed

Examples

These show non-obvious response structures. For straightforward methods, use the API reference above.

Sleep (nested structure)

sleep = client.get_sleep_data(today)
daily = sleep.get("dailySleepDTO", {})
if daily:
    total_h = daily.get("sleepTimeSeconds", 0) / 3600
    deep_h = daily.get("deepSleepSeconds", 0) / 3600
    rem_h = daily.get("remSleepSeconds", 0) / 3600
    print(f"Sleep: {total_h:.1f}h (deep {deep_h:.1f}h, REM {rem_h:.1f}h)")
    score = daily.get("sleepScores", {}).get("overall", {}).get("value")
    print(f"Score: {score}/100")

Training Status (deeply nested by device)

ts = client.get_training_status(today)
if ts:
    vo2 = ts.get('mostRecentVO2Max', {}).get('generic', {})
    print(f"VO2 Max: {vo2.get('vo2MaxPreciseValue', 'N/A')}")

    status_data = ts.get('mostRecentTrainingStatus', {}).get('latestTrainingStatusData', {})
    if status_data:
        device_id = list(status_data.keys())[0]
        device = status_data[device_id]
        print(f"Status: {device.get('trainingStatusFeedbackPhrase')}")
        acute = device.get('acuteTrainingLoadDTO', {})
        print(f"Load: {acute.get('dailyTrainingLoadAcute')} (ACWR: {acute.get('acwrStatus')})")

Stress (durations are in get_stats, not get_stress_data)

stats = client.get_stats(today)
stress_data = client.get_stress_data(today)
print(f"Avg stress: {stress_data.get('avgStressLevel')}/100")
# Duration fields are in get_stats(), not get_stress_data()
rest_min = stats.get("restStressDuration", 0) / 60
low_min = stats.get("lowStressDuration", 0) / 60
print(f"Rest: {rest_min:.0f}min, Low: {low_min:.0f}min")

Quick Reference

# Unit conversions
distance_km = activity.get("distance", 0) / 1000
duration_min = activity.get("duration", 0) / 60
speed_kmh = activity.get("averageSpeed", 0) * 3.6
sleep_hours = daily.get("sleepTimeSeconds", 0) / 3600

# Pace calculation
if activity.get("distance", 0) > 0:
    pace = (activity["duration"] / 60) / (activity["distance"] / 1000)
    print(f"Pace: {int(pace)}:{int((pace % 1) * 60):02d}/km")

Re-authentication

If queries fail with auth errors, the session has expired. Re-run the authentication flow above. If the user's password changed, ask for the new one and update .env.

Debugging

If a method call fails or you're unsure what's available, introspect:

uv run -c "from garminconnect import Garmin; print([m for m in dir(Garmin) if not m.startswith('_')])"

Troubleshooting

• "Not authenticated": Run the authentication flow from the Setup section
• Session expired: Re-run authentication (sessions last ~1 year)
• Rate limiting (429): Add time.sleep(0.5) between requests
• Field is None: Some metrics require specific Garmin devices
• MFA issues: User may need to check email or authenticator app for the code
