> **[Health Sync for Google Health | Homey](https://homey.app/en-us/app/io.github.fbnlrz.healthsync/Health-Sync-for-Google-Health/test/)** > > Your steps, heart rate, sleep and weight from Google Health on Homey ![Health Sync for Google Health](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/a/ba5c9318b253f9ba8e5ca822d523c1d8bd2303e5.png) **Bring your health data to Homey!** This app connects Homey Pro to the **Google Health API** and turns your steps, heart rate, sleep, weight and more into Homey device capabilities — with full **Insights** history and a rich set of **Flow cards**. Works with any data source that feeds Google Health (Pixel Watch, Fitbit, and other connected apps/devices). ## 📊 16 sensors, all with Insights | Activity | Heart | Body | Sleep & more | | --- | --- | --- | --- | | Steps today | Heart rate (latest) | Weight | Sleep last night (h) | | Distance today | Resting heart rate | Body fat | Water intake today | | Calories today | Heart rate variability (HRV) | Blood oxygen (SpO2) | | | Active calories today | VO2 max | Respiratory rate | | | Floors today | | | | | Active zone minutes | | | | Daily counters reset at local midnight automatically. ## 🔧 Setup Google grants Health API access per Google Cloud project, so you bring your own (free) OAuth client — the app’s settings page walks you through it step by step: 1. Create a (free) project in the [Google Cloud Console](https://console.cloud.google.com/) and enable the [Google Health API](https://console.cloud.google.com/apis/api/health.googleapis.com) 2. Create an OAuth client (type _Web application_) with redirect URI `https://callback.athom.com/oauth2/callback` and add yourself as a test user 3. Paste Client ID + Secret into the app settings, then add the “Google Health” device and sign in 4. **Important:** tick ALL permission checkboxes on Google’s consent screen (Google leaves them unchecked by default) ## 🧪 Test version 👉 **[Install the test version](https://homey.app/a/io.github.fbnlrz.healthsync/test/)** Known limitations while testing: - Data arrives via polling (configurable, 5–1440 min) — no realtime push yet - While your Google consent screen is in “Testing” mode, Google expires logins after 7 days → just use _Repair_ on the device (or publish your consent screen to make logins permanent) Feedback, bug reports and feature requests are very welcome — either here or on [GitHub](https://github.com/fbnlrz/homey-health/issues). ## 🔒 Privacy & security Health data is sensitive, and this app was largely written by an AI — so here is exactly where your data goes, all of it verifiable in the [public source code](https://github.com/fbnlrz/homey-health): - **Your data never touches my servers — there are none.** The app runs 100% locally on your Homey Pro and talks to exactly one endpoint: Google’s Health API (`health.googleapis.com`), plus Google’s OAuth endpoints for login. No telemetry, no analytics, no third-party services. - **You own the API access.** The OAuth client belongs to _your own_ Google Cloud project. I never see your Client ID, secret, tokens or any health data — I couldn’t even if I wanted to. - **Tokens stay on your Homey.** Access/refresh tokens are stored in Homey’s device store on your Homey Pro, nowhere else. - **Read-only by default.** The app only requests read scopes. Write access (for the “Log weight/body fat” Flow cards) is opt-in and off by default. - **Zero runtime dependencies.** No third-party npm packages in the app — just Node.js built-ins and the official Homey SDK. Nothing to hide in, small attack surface, quick to audit. - **No special Homey permissions.** The manifest’s permission list is empty. - **Fully open source (MIT).** Every line is public. The AI-generated code went through a multi-agent adversarial review _and_ you’re welcome to review it yourself — that’s the honest answer to “can I trust vibe-coded software”: don’t trust, verify. ## 🤖 Credits & sources This app was built end-to-end with **Claude Fable 5** (Anthropic) in Claude Code — as a real-world test of Fable 5’s capabilities: multi-agent code-review workflows with adversarial verification, reverse-engineering the API semantics from CLI source code, logo design rendered via headless Chromium, and live debugging against a real Homey Pro.

Hi 🙂 Will edit the Post 🙂 Thanks!! ---

## Update: Health Report (PDF) & Asleep sensor 🎉 A big update just landed on the test channel: **📄 Printable health report** — Google Health itself has no PDF export, so the app now does it for you: open the app settings, pick a period (14/30/60/90 days) and generate a report with summary stats, trend charts (steps, resting heart rate, sleep, weight) and a full daily-values table — made to hand to your doctor. It renders dark on screen and switches to a clean light layout automatically when you print / save as PDF. Under the hood the report is served briefly (5 minutes) from your Homey Pro on your local network, protected by a freshly generated one-time password — nothing ever leaves your home. **😴 New “Asleep” sensor** — realtime sleep state isn’t possible with the Google Health API (sleep sessions sync after you wake), so this is a pragmatic hybrid: set it via the new _“Mark as asleep”_ flow action in your bedtime routine (e.g. phone starts charging after 10 pm), and it flips back to awake **automatically** when your freshly ended night’s sleep syncs. Comes with an _Asleep/Awake_ condition card and Insights history of your sleep windows. **🩸 SpO2 fix** — blood oxygen now uses Google’s daily summary instead of raw spot readings, so a single low-confidence sample (looking at you, 50 %) no longer skews the value. Update via the [test link](https://homey.app/de-de/app/io.github.fbnlrz.healthsync/Health-Sync-f%C3%BCr-Google-Health/test/) — feedback very welcome! ---

**Update — v0.4.0 (Test)** New test build is live. This one is all about **more data and better accuracy**. **New health data (all with Insights):** - 🍎 Nutrition: calorie intake, carbs, protein, fat - 🩸 Blood glucose (+ a Flow trigger for new measurements) - 🔥 Basal calories & 🪑 sedentary minutes - 🌬 Respiratory rate, 💨 VO2 max, ⛰ altitude - 🌡 Skin-temperature variation (the deviation-from-baseline value your wearable actually reports during sleep) - ❤ Optional ECG & irregular-heart-rhythm data — off by default, needs an extra Google permission you can enable in the app settings **Fixed:** - Water, nutrition macros and sedentary minutes now read correctly from Google Health (they were coming up empty before) - More accurate blood-glucose parsing A quick note on empty tiles: if something like floors, VO2 max or core body temperature stays blank, it usually just means Google Health has no data of that type for your account/device — not a bug. The app now logs per-type diagnostics, so if you think a value _should_ be there, grab the `[diag]` line from the app log and I’ll take a look. As always: still built and tested with **Claude Fable 5** , and it only talks to _your own_ Google Cloud project — no data ever passes through me. Feedback and logs welcome. 🙏 ---

**Update — v0.5.0 (Test)** This release adds **dashboard widgets** and makes the health report a lot friendlier. **New: dashboard widgets** (light/dark aware) - **Health tile** — a compact tile for a single metric. Pick any of the ~24 data points, the device, and an accent colour. Add one per data point to build your own row of tiles. - **Health overview** — several key values at a glance in one card; choose which ones via checkboxes, and it only shows metrics that actually have data. - Each metric gets a **data-type-matched icon** — an ECG zig-zag for heart rate, waves for water, a moon for sleep, a flame for calories, footsteps for steps, and so on. **Health report improvements** - 🧩 **Customize it right on the page** — tick/untick whole sections (patient details, summary, individual charts, daily table, disclaimer) and individual table columns. Unticked parts aren’t printed or saved to the PDF, and your choices are remembered. - 📋 **One-tap copyable password** — no more typing the access password by hand. - 📱 **Fixed report generation in the mobile app** — it previously only worked on a PC; now it works the same on your phone. As always: built and tested with **Claude Fable 5** ---
