Why Track It

Why it matters

Build a long-term weight history, track trends without relying on any app, and get alerts when you hit milestones.

Automations

What you can do with Weight data.

HC Webhook sends weight readings to any webhook — here are ideas to get you started.

Weigh-In Log in Google Sheets

Every time you log a weight, it gets appended to a spreadsheet with the date automatically.

Weight Trend Chart

Feed weight data into InfluxDB and chart your rolling 30-day trend in Grafana.

Goal Milestone Alert

Send a notification when your weight crosses a target you set — for gains or losses.

Weekly Average Report

Calculate a 7-day average weight in n8n and send it to yourself every Monday to reduce noise from daily fluctuations.

BMI Calculator

Combine weight with your height in an n8n formula to log your BMI alongside each weigh-in.

Body Composition Log

Store weight alongside body fat percentage and lean mass in Notion for a full body composition history.

Data Format

What the JSON looks like.

HC Webhook posts a JSON object containing a weight array to your endpoint on every sync.

{
  "timestamp": "2026-04-15T07:30:00Z",
  "weight": [
    { "kg": 78.4, "time": "2026-04-15T07:30:00Z" }
  ]
}

How to Export

Get Weight out of Health Connect

Google Health Connect stores your weight data from compatible apps (Samsung Health, Fitbit, Garmin, and more). HC Webhook reads that data on a schedule you set and forwards it as JSON to any URL you add — n8n, Home Assistant, Zapier, or your own API.
