garmin-grafana

garmin-grafana is a dockerized Python application that automatically fetches health data from Garmin smartwatches and stores it in InfluxDB for custom visualization and analysis via Grafana. It enables users to maintain local ownership of personal health metrics without sharing data with third parties.

What garmin-grafana is

The project uses Python to query the Garmin Connect API, persists time-series data in InfluxDB, and provides Grafana dashboard templates for visualization of comprehensive health metrics (HR, sleep, steps, stress, body battery, GPS workouts). It supports Docker/Docker Compose deployment, Kubernetes via Helm, and includes historical data backfill capabilities.

Quickstart

Get the garmin-grafana source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/arpanghosh8453/garmin-grafana.git2cd garmin-grafana3# follow the project's README for install & configuration

Best use cases

Personal Health Data Privacy & Retention

Self-host complete Garmin health history locally without relying on Garmin's cloud or third-party analytics platforms. Retain full ownership and control of sensitive biometric data.

Advanced Custom Dashboard Analytics

Build bespoke Grafana dashboards combining multiple metrics (HR zones, sleep patterns, stress, body battery, GPS workouts) with custom alerts and time-window analysis beyond Garmin app capabilities.

Long-Term Trend Analysis & Export

Export health metrics as CSV for advanced analysis in Python, Excel, or ML workflows. Discover patterns and correlations across months/years of granular data not surfaced in standard Garmin reports.

Implementation considerations

Garmin account credentials (or OAuth tokens) must be securely stored in container environment or config; requires 2FA handling if enabled on Garmin account.
InfluxDB instance must be provisioned and configured alongside the fetch container; requires disk space planning for historical data retention (weeks/months of metric density).
Initial setup fetches only last 7 days by default; manual CLI commands required to backfill historical data (bulk import from Garmin Connect exports also supported).
Data fetch frequency is configurable but impacts Garmin API rate limits and local resource usage; no documented rate-limit handling published.
Grafana dashboard templates provided but assume some familiarity with dashboard editing and metric naming conventions in InfluxDB.

When to avoid it — and what to weigh

No Garmin Device Ownership — This tool exclusively integrates with Garmin Connect API. Users without a compatible Garmin smartwatch cannot benefit.
Minimal Self-Hosting Comfort — Requires Docker, Linux CLI familiarity, and ongoing infrastructure management (InfluxDB backups, container updates). Not suitable for users avoiding server administration.
Real-Time Mobile or Cross-Device Access — Grafana access is local/LAN-based by default; public cloud hosting and mobile-first apps require additional configuration. Not a replacement for Garmin's official mobile app for on-the-go use.
Dependency on Garmin API Stability — Project reverse-engineers or relies on undocumented Garmin APIs. API changes or Garmin account lockouts can break data sync without vendor commitment to API stability.

License & commercial use

BSD 3-Clause License. Permits commercial and proprietary use, modification, and redistribution provided the license text and original author attribution are retained. No copyleft obligations.

BSD 3-Clause is a permissive OSI-approved license allowing commercial use without restriction. However, integration with Garmin Connect API is subject to Garmin's Terms of Service; the project disclaimer explicitly states it is not affiliated with or endorsed by Garmin Ltd. Any commercial offering must verify compliance with Garmin's ToS separately—license permissiveness does not override API provider restrictions.

Security considerations

Garmin account credentials stored in container environment variables or config files; no documented encryption-at-rest or secret management integration (Vault, Kubernetes Secrets). OAuth token refresh mechanism not detailed. InfluxDB and Grafana deployed locally; exposure to network attacks depends on user's firewall/network isolation. Health data sensitivity warrants careful access control; project provides no built-in audit logging or RBAC. Reverse engineering or unofficial API reliance poses risk of account lockout or data loss if Garmin changes API contract.

Alternatives to consider

Garmin Connect Web/Mobile App

Official, first-party solution with vendor support and API stability guarantees. Trade-off: limited customization, cloud-hosted data, no CSV export of raw metrics, no local ownership.

Fitbit + fitbit-grafana (sister project)

Similar self-hosted dashboard architecture for Fitbit users. Useful if switching from Garmin or operating multi-device ecosystem.

Strava + Grafana or Tableau

Sports-focused alternative with strong GPS workout data and social features. Less comprehensive for daily health metrics (sleep, stress, body battery). Requires Strava subscription for advanced export.

garmin-grafana FAQ

What health metrics does garmin-grafana collect?

Heart rate, steps, sleep (including SpO2, breathing rate, HRV), stress, body battery, calories, activity minutes, HR zones, sleep regularity, workout GPS data (track, pace, altitude), and more. Essentially mirrors Garmin Connect data minus Garmin's proprietary algorithms.

Is my data encrypted in transit and at rest?

Unknown/Not clearly stated. Documentation does not specify TLS usage for Garmin API calls or encryption-at-rest for InfluxDB. Users should assume data is stored unencrypted locally unless additional hardening is applied.

What happens if Garmin changes their API?

Data sync will break. The project relies on reverse-engineered or undocumented Garmin APIs without vendor commitment. Maintainers would need to update code post-incident. No SLA or guarantee of timely fix.

Can I run this in production at scale (multiple users, cloud)?

Kubernetes/Helm support exists, but documentation does not address multi-tenant isolation, data persistence, secret management, or cloud security best practices. Requires custom hardening for production use.
