Send a notification in the afternoon if you have only hit half your daily water target.

Hydration Log in Google Sheets

Append daily intake to a spreadsheet to track patterns across weeks.

Weekly Hydration Report

Email yourself a weekly average and highlight days where you fell short.

Home Assistant Water Tracker

Show your daily water intake on a Home Assistant dashboard and trigger a reminder at set intervals.

Correlation with Energy Levels

Log hydration alongside sleep and step data to see if hydration affects your activity levels.

Streak Tracker

Build a Notion tracker that marks each day green or red based on whether you hit your water goal.

How to Export

Get Hydration out of Health Connect

Google Health Connect stores your hydration 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.

  1. 01

    Install HC Webhook and grant Health Connect permission for Hydration.

  2. 02

    Paste your webhook URL — Home Assistant, n8n, Zapier, or any endpoint.

  3. 03

    Set your sync schedule. Hydration readings arrive automatically, every time.
