Fitbit Analytics

Quick Start

# Set Fitbit API credentials
export FITBIT_CLIENT_ID="your_client_id"
export FITBIT_CLIENT_SECRET="your_client_secret"
export FITBIT_ACCESS_TOKEN="your_access_token"
export FITBIT_REFRESH_TOKEN="your_refresh_token"

# Generate morning briefing with Active Zone Minutes
python scripts/fitbit_briefing.py

# Fetch daily steps
python scripts/fitbit_api.py steps --days 7

# Get heart rate data
python scripts/fitbit_api.py heartrate --days 7

# Sleep summary
python scripts/fitbit_api.py sleep --days 7

# Generate weekly health report
python scripts/fitbit_api.py report --type weekly

# Get activity summary
python scripts/fitbit_api.py summary --days 7

When to Use

Use this skill when:

• Fetching Fitbit metrics (steps, calories, heart rate, sleep)
• Analyzing activity trends over time
• Setting up alerts for inactivity or abnormal heart rate
• Generating daily/weekly health reports

Core Workflows

1. Daily Briefing

# Generate morning health briefing (includes Active Zone Minutes)
python scripts/fitbit_briefing.py                    # Today's briefing
python scripts/fitbit_briefing.py --date 2026-01-20  # Specific date
python scripts/fitbit_briefing.py --format brief     # 3-line summary
python scripts/fitbit_briefing.py --format json      # JSON output

# Example output includes:
# - Yesterday's activities (logged exercises)
# - Yesterday's Active Zone Minutes (total, Fat Burn, Cardio, Peak)
# - Today's activity summary (steps, calories, floors, distance)
# - Heart rate (resting, average, zones)
# - Sleep (duration, efficiency, awake episodes)
# - Trends vs 7-day average

Example JSON output:

{
  "date": "2026-01-21",
  "steps_today": 8543,
  "calories_today": 2340,
  "distance_today": 6.8,
  "floors_today": 12,
  "active_minutes": 47,
  "resting_hr": 58,
  "avg_hr": 72,
  "sleep_hours": 7.2,
  "sleep_efficiency": 89,
  "awake_minutes": 12,
  "yesterday_activities": [
    {"name": "Run", "duration": 35, "calories": 
  
   
     
     
     
  

Note: Cardio Load is NOT available via Fitbit API - it's a Fitbit Premium feature only visible in the mobile app.

2. Data Fetching (CLI)

# Available commands:
python scripts/fitbit_api.py steps --days 7
python scripts/fitbit_api.py calories --days 7
python scripts/fitbit_api.py heartrate --days 7
python scripts/fitbit_api.py sleep --days 7
python scripts/fitbit_api.py summary --days 7
python scripts/fitbit_api.py report --type weekly

3. Data Fetching (Python API)

export PYTHONPATH="{baseDir}/scripts"
python - <<'PY'
from fitbit_api import FitbitClient

client = FitbitClient()  # Uses env vars for credentials

# Fetch data (requires start_date and end_date)
steps_data = client.get_steps(start_date="2026-01-01", end_date="2026-01-16")
hr_data = client.get_heartrate(start_date="2026-01-01", end_date="2026-01-16")
sleep_data = client.get_sleep(start_date="2026-01-01", end_date="2026-01-16")
activity_summary = client.get_activity_summary(start_date="2026-01-01", end_date="2026-01-16")
PY

4. Analysis

export PYTHONPATH="{baseDir}/scripts"
python - <<'PY'
from fitbit_api import FitbitAnalyzer

analyzer = FitbitAnalyzer(steps_data, hr_data)
summary = analyzer.summary()
print(summary)  # Returns: avg_steps, avg_resting_hr, step_trend
PY

5. Alerts

python {baseDir}/scripts/alerts.py --days 7 --steps 8000 --sleep 7

Authentication

Fitbit API requires OAuth 2.0 authentication:

1. Create app at: https://dev.fitbit.com/apps
2. Get client_id and client_secret
3. Complete OAuth flow to get access_token and refresh_token
4. Set environment variables or pass to scripts

Environment

Required:

• FITBIT_CLIENT_ID
• FITBIT_CLIENT_SECRET
• FITBIT_ACCESS_TOKEN
• FITBIT_REFRESH_TOKEN

Automation (Cron Jobs)

Cron jobs are configured in ThinkFleet's gateway, not in this repo. Add these to your ThinkFleet setup:

Daily Morning Briefing (8:00 AM)

thinkfleet cron add \
  --name "Morning Fitbit Health Report" \
  --cron "0 8 * * *" \
  --tz "America/Los_Angeles" \
  --session isolated \
  --wake next-heartbeat \
  --deliver \
  --channel telegram \
  --target "<YOUR_TELEGRAM_CHAT_ID>" \
  --message "python3 /path/to/your/scripts/fitbit_briefing.py --format text"

Note: Replace /path/to/your/ with your actual path and <YOUR_TELEGRAM_CHAT_ID> with your Telegram channel/group ID.
