# Fitbit Analytics ## Quick Start ```bash # 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 ```bash # 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:** ```json { "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": 320} ], "yesterday_azm": { "activeZoneMinutes": 61, "fatBurnActiveZoneMinutes": 39, "cardioActiveZoneMinutes": 22 } } ``` **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) ```bash # 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) ```bash 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 ```bash 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 ```bash python {baseDir}/scripts/alerts.py --days 7 --steps 8000 --sleep 7 ``` ## Scripts - `scripts/fitbit_api.py` - Fitbit Web API wrapper, CLI, and analysis - `scripts/fitbit_briefing.py` - Morning briefing CLI (text/brief/json output) - `scripts/alerts.py` - Threshold-based notifications ## Available API Methods | Method | Description | |--------|-------------| | `get_steps(start, end)` | Daily step counts | | `get_calories(start, end)` | Daily calories burned | | `get_distance(start, end)` | Daily distance | | `get_activity_summary(start, end)` | Activity summary | | `get_heartrate(start, end)` | Heart rate data | | `get_sleep(start, end)` | Sleep data | | `get_sleep_stages(start, end)` | Detailed sleep stages | | `get_spo2(start, end)` | Blood oxygen levels | | `get_weight(start, end)` | Weight measurements | | `get_active_zone_minutes(start, end)` | Active Zone Minutes (AZM) breakdown | ## References - `references/api.md` - Fitbit Web API documentation - `references/metrics.md` - Metric definitions and interpretations ## 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 OpenClaw's gateway, not in this repo. Add these to your OpenClaw setup: ### Daily Morning Briefing (8:00 AM) ```bash openclaw 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.
