Sync Withings health data to the local cache.

Fetches data from the Withings API and stores it in SQLite for fast offline queries. Run this before using other withings_get_* tools.

Syncs incrementally: only fetches data newer than the last sync. First sync fetches the specified number of days of history.

Args: data_types: What to sync. Options: "all", "body", "sleep", "activity", "workouts". Comma-separated for multiple, e.g. "body,sleep". Default: "all". days: Days of history for first sync (default: 30). Ignored on subsequent syncs (uses last sync timestamp).

Returns summary of records synced per data type. Not for querying data - use withings_get_body, withings_get_sleep, withings_get_activity, or withings_get_workouts instead.

Get daily activity summaries (steps, distance, calories, active time).

Returns one entry per day from the local cache by default. Run withings_sync first to populate the cache.

Args: start_date: Start date as "YYYY-MM-DD", "YYYY-MM", or "30d". Default: last 30 days. end_date: End date as "YYYY-MM-DD". Default: today. live: If true, fetch from Withings API instead of cache.

Returns daily activity data sorted by date, with steps, distance in km, calories, and active minutes by intensity level. Not for workout sessions -- use withings_get_workouts instead.

Get workout sessions (type, duration, HR, calories).

Returns individual workout sessions from the local cache by default. Run withings_sync first to populate the cache.

Args: start_date: Start date as "YYYY-MM-DD", "YYYY-MM", or "90d". Default: last 90 days. end_date: End date as "YYYY-MM-DD". Default: today. category: Filter by workout type, e.g. "cycling", "walk", "run". Case-insensitive partial match. live: If true, fetch from Withings API instead of cache.

Returns workout sessions sorted by date with type, duration, calories, distance, and heart rate data. Not for daily step/activity totals -- use withings_get_activity.

Analyse trends in cached health data.

Computes averages, min/max, and changes over time from the local cache. Auto-syncs if the cache is stale (no sync today).

Args: data_type: What to analyse. Options: "body", "sleep", "activity". period: Aggregation period. Options: "weekly", "monthly", "quarterly". Default: "monthly". start_date: Start date as "YYYY-MM-DD" or "12m" for relative. Default: last 12 months. end_date: End date as "YYYY-MM-DD". Default: today. compare: Compare two periods. Format: "last_30d vs previous_30d", "2026-03 vs 2026-02", "2026-Q1 vs 2025-Q4". When set, period/start_date/end_date are ignored.

Returns aggregated averages with change indicators. For body data: weight, fat%, muscle trends. For sleep: duration, score, HR trends. For activity: steps, distance, calorie trends. Not for raw data -- use withings_get_body/sleep/activity instead.

Get body composition measurements (weight, fat, muscle, etc.).

Returns measurements from the local cache by default. Use live=True to fetch directly from Withings API. Run withings_sync first to populate the cache.

Args: start_date: Start date as "YYYY-MM-DD", "YYYY-MM", or "30d" for relative days. Default: last 30 days. end_date: End date as "YYYY-MM-DD". Default: today. metrics: Comma-separated metric filter, e.g. "weight_kg,fat_pct". Default: all available metrics. Options: weight_kg, fat_pct, fat_mass_kg, muscle_mass_kg, hydration_kg, bone_mass_kg, heart_rate, systolic_bp, diastolic_bp, spo2_pct. live: If true, fetch from Withings API instead of cache.

Returns measurements sorted by date, one entry per measurement group. Not for sleep or activity data -- use withings_get_sleep or withings_get_activity instead.

Get connected Withings devices with battery and firmware info.

Always fetched live from the Withings API.

Returns device type, model name, battery level (high/medium/low), and last session date for each connected device.

Get ECG recordings and atrial fibrillation detection results.

Always fetched live from the Withings API (not cached due to large signal data). Requires a Withings device with ECG capability (ScanWatch, BPM Core).

Args: start_date: Start date as "YYYY-MM-DD" or "30d". Default: last 30 days. end_date: End date as "YYYY-MM-DD". Default: today.

Returns ECG recording list with timestamps, AFib classification (negative/positive/inconclusive), and heart rate. Does not include raw signal waveforms. For resting heart rate trends, use withings_get_body or withings_get_sleep instead.

Get sleep data (summaries or detailed phases).

Summary mode (default): nightly totals with duration, sleep score, HR, respiratory rate, and snoring. From local cache unless live=True.

Detail mode (detail=True): minute-by-minute sleep phases (awake, light, deep, REM) with HR and respiratory rate. Always fetched live. Maximum 7 days per request (Withings API limit).

Args: start_date: Start date as "YYYY-MM-DD", "YYYY-MM", or "7d". Default: last 7 days (detail) or last 30 days (summary). end_date: End date as "YYYY-MM-DD". Default: today. detail: If true, return minute-by-minute sleep phases instead of nightly summaries. Always live, max 7 days. live: If true, fetch summaries from API instead of cache. Ignored when detail=True (always live).

Returns nightly sleep data sorted by date. Not for body composition -- use withings_get_body instead.
