Withings Family

This skill allows you to interact with Withings accounts for multiple family members to retrieve comprehensive health metrics from Withings devices (smart scales, sleep analyzers, activity trackers, etc.).

Multi-User Support

This skill natively supports multiple users with per-user token files:

tokens-alice.json
tokens-bob.json
tokens-charlie.json

Each family member authenticates once via OAuth. Their tokens are stored separately and refreshed automatically. No token copying or switching required — just pass the user ID as the first argument.

python3 scripts/withings.py alice weight
python3 scripts/withings.py bob sleep
python3 scripts/withings.py charlie activity

When to Use This Skill

Use this skill when the user:

• Asks about their weight or weight history
• Wants to see their body composition (fat %, muscle mass, bone mass, hydration)
• Requests their daily activity (steps, distance, calories burned)
• Asks about their sleep data (duration, quality, deep sleep, REM)
• Mentions "Withings" or any Withings device (Body+, Sleep Analyzer, ScanWatch, etc.)
• Wants to track their or their family's health progress over time

Setup: Creating a Withings Developer App

Before using this skill, you need to create a free Withings developer application to get your API credentials.

Step 1: Create a Withings Developer Account

1. Go to Withings Developer Portal
2. Click Sign Up or Log In if you already have a Withings account
3. Accept the Developer Terms of Service

Step 2: Create Your Application

1. Navigate to My Apps → Create an Application
2. Fill in the application details:
   • Application Name: Choose a name (e.g., "My Clawdbot Health")
   • Description: Brief description of your use case
   • Contact Email: Your email address
   • Callback URL: http://localhost:18081 (required for OAuth)
   • Application Type: Select "Personal Use" or appropriate type
3. Submit the application

Step 3: Get Your Credentials

Once your application is created:

1. Go to My Apps and select your application
2. You'll find:
   • Client ID → Set as WITHINGS_CLIENT_ID environment variable
   • Client Secret → Set as WITHINGS_CLIENT_SECRET environment variable

Step 4: Configure Environment Variables

Add these to your Clawdbot environment:

export WITHINGS_CLIENT_ID="your_client_id_here"
export WITHINGS_CLIENT_SECRET="your_client_secret_here"

Or create a .env file in ~/.clawdbot/withings-family/.env:

WITHINGS_CLIENT_ID=your_client_id_here
WITHINGS_CLIENT_SECRET=your_client_secret_here

Configuration

The skill provides two scripts (in scripts/):

• scripts/withings_oauth_local.py — Automatic OAuth with local callback server (recommended)
• scripts/withings.py — Main CLI + manual OAuth

Credentials location: ~/.clawdbot/withings-family/

• .env — Client ID/Secret (optional, can use ENV vars instead)
• tokens-<userId>.json — OAuth tokens per user (mode 600)

Before any data retrieval, check if the user is authenticated. If an error mentions "No token found", guide the user through the initial authentication process for that specific user.

Authentication Methods

Method A: Automatic OAuth (Recommended)

Uses a local callback server to capture the code automatically:

python3 {baseDir}/scripts/withings_oauth_local.py <userId>

Example:

python3 {baseDir}/scripts/withings_oauth_local.py alice

The script will:

1. Print the authorization URL
2. Start a local server on localhost:18081
3. Wait for the redirect
4. Automatically capture the code and exchange for tokens
5. Save tokens to tokens-<userId>.json

Method B: Manual OAuth

Traditional two-step flow (see "Authentication" command below).

Available Commands

All commands follow the format:

python3 {baseDir}/scripts/withings.py <userId> <command> [options]

1. Authentication

First-time setup for a user — generates the OAuth URL:

python3 {baseDir}/scripts/withings.py alice auth

After the user visits the URL and gets the authorization code:

python3 {baseDir}/scripts/withings.py alice auth YOUR_CODE_HERE

Repeat for each family member who needs access.

2. Get Weight

Retrieve the latest weight measurements:

python3 {baseDir}/scripts/withings.py alice weight

Returns the 5 most recent weight entries in JSON format.

Example output:

[
  { "date": "2026-01-17T08:30:00.000Z", "weight": "75.40 kg" },
  { "date": "2026-01-16T08:15:00.000Z", "weight": "75.65 kg" }
]

3. Get Body Composition

Retrieve comprehensive body metrics (fat, muscle, bone, water, BMI):

python3 {baseDir}/scripts/withings.py alice body

Returns the 5 most recent body composition measurements.

Example output:

[
  {
    "date": "2026-01-17T08:30:00.000Z",
    "weight": "75.40 kg",
    "fat_percent": "18.5%",
    "fat_mass": "13.95 kg",
    "muscle_mass": "35.20 kg",
    "bone_mass": "3.10 kg",
    "hydration": "55.2%"
  }
]

4. Get Activity

Retrieve daily activity data (steps, distance, calories):

python3 {baseDir}/scripts/withings.py alice activity

Optionally specify the number of days (default: 7):

python3 {baseDir}/scripts/withings.py alice activity 30

Example output:

[
  {
    "date": "2026-01-17",
    "steps": 8542,
    "distance": "6.23 km",
    "calories": 2150,
    "active_calories": 450,
    "soft_activity": "45 min",
    "moderate_activity": "22 min",
    "intense_activity": "8 min"
  }
]

5. Get Sleep

Retrieve sleep data and quality:

python3 {baseDir}/scripts/withings.py alice sleep

Optionally specify the number of days (default: 7):

python3 {baseDir}/scripts/withings.py alice sleep 14

Example output:

[
  {
    "date": "2026-01-17",
    "start": "23:15",
    "end": "07:30",
    "duration": "8h 15min",
    "deep_sleep": "1h 45min",
    "light_sleep": "4h 30min",
    "rem_sleep": "1h 30min",
    "awake": "30min",
    "sleep_score": 82
  }
]

Error Handling

Common errors and how to resolve them:

Notes

• Multi-user: Each family member has their own token file (tokens-{userId}.json)
• Token refresh: Tokens are automatically refreshed when they expire
• Scopes: Withings API scopes used: user.metrics, user.activity
• Device support: Data availability depends on which Withings devices the user owns
• Body composition: Requires a compatible smart scale (e.g., Body+, Body Comp)
