What it does

Read body metrics from a Wyze smart scale — weight, BMI, body fat, water, muscle, BMR. Supports multiple household members. Unofficial Wyze API via wyze-node.

The skill document

Wyze scale (body metrics)

Read body-composition data from a Wyze smart scale via the bundled scale CLI, which wraps wyze-node. Reuses the same cached login as the wyze skill (no password).

Unofficial: wyze-node uses Wyze's developer API Key auth and reverse-engineered endpoints. Not affiliated with or endorsed by Wyze; Wyze may change their API at any time.

When to use

Questions about weight or body composition: "what's my weight", "what's my BMI / body fat", "am I down since last time", weigh-in history/trend. A single scale can hold several people — scope a reading to a specific member by name.

Setup (once)

This skill shares the wyze skill's setup. If you haven't already:

  1. Install the dependency: npm install --prefix "{baseDir}/scripts" wyze-node (or have wyze-node installed globally, or set WYZE_NODE_DIR to a clone).
  2. Put WYZE_EMAIL, WYZE_KEY_ID, WYZE_API_KEY in WYZE_ENV (default ~/.openclaw/secrets/wyze.env) — keys from https://developer-api-console.wyze.com/#/apikey/view
  3. Cache a login token in a terminal once, using the wyze skill's login command (the token is shared between both skills).

Run

node "{baseDir}/scripts/scale" [latest|history|users] [args]
  • latest [user] (default) — most recent weigh-in: weight (kg + lb), BMI, body fat, body water, muscle, BMR, metabolic age, date, and change vs the prior reading. Pass a member name or id to scope it.
  • history [n] [user] — last n weigh-ins (default 7) with weight + date, optionally for one member.
  • users — list members the scale knows about (or the raw user ids seen in records if no named members are configured).

`` is a case-insensitive substring of a member's nickname, or a raw member id. Omit it to use the most recent weigh-in regardless of member.

Configuration (shared with the wyze skill)

  • WYZE_NODE_DIR (default ~/code/wyze-node) or an npm-installed wyze-node
  • WYZE_ENV (default ~/.openclaw/secrets/wyze.env) — WYZE_EMAIL, WYZE_KEY_ID, WYZE_API_KEY
  • WYZE_TOKEN_DIR (default: WYZE_NODE_DIR if present, else ~/.openclaw/wyze)

Privacy

Body metrics are sensitive personal data. Share a reading only with its owner in a private/direct session — never surface anyone's weight or body composition in group chats or shared surfaces.

Notes

  • The scale device is product_type WyzeScale. Weight is stored in kg; the CLI also prints pounds.
  • Backed by wyze-node. If calls fail with auth errors, re-run the wyze skill's login to refresh the cached token.
  • License: MIT. Backed by the open-source wyze-node client.
