GarminDB

yes, but the GarminDB [0] project still manages to get most available data by impersonating a browser (admittedly that could be broken eventually). If that happens in the future, I'll probably revisit making an entire tracking app for myself. [0] https://github.com/tcgoetz/GarminDB

Same here. I've been scraping the data from my Garmin watch for years with very little problems (first with https://github.com/tcgoetz/GarminDB, then https://github.com/sealbro/dotnet.garmin.connect). The only annoyance is that Garmin requires 2FA if you enable the ECG feature on your smart watch/fitness tracker, but I have a small program that reads the 2FA codes from my Gmail inbox and supplies them to the scraper without too much trouble.

You might take a look at https://github.com/tcgoetz/GarminDB

If you've got a Garmin device check out GarminDB [0]. Garmin actually exposes an API that you can access with your credentials and get the raw activity, heart rate, etc data. [0]: https://github.com/tcgoetz/GarminDB

How are you syncing/storing the data? I've been a Garmin user for nearly a decade and would really like to get the data off their platform so I can do more with it. There are a few self-hosted options (https://github.com/tcgoetz/GarminDB seems like the best) but I keep kicking that can down the road.

I got myself a Garmin watch at the beginning of the year, to collect various metrics automatically. The watch uses the built in heart rate monitor/sensors to derive various data specifically: - sleep hours (including the sleep phase type: deep sleep etc) - stress amounts (via heart rate variability) - energy levels ("Body battery" in Garmin speak) I've been feeling quite drained the last couple of weeks so I wanted to see if the data I've collected over the last 3 months or so would match what I was subjectively feeling. Interestingly Garmin does not provide any functionality to analyze long term trends, but there's an open source project to extract data from Garmin [0]. I used the tool to generate some graphs [1] that, do indeed, seem to indicate a rising level of stress over the last few months. I'm going to try the moving average next

You can sync Garmin (many devices) health tracker data locally via USB cable or wireless receiver, then parse/graph with OSS scripts: Code: https://github.com/tcgoetz/GarminDB & https://github.com/mrihtar/Garmin-FIT Wireless receiver: https://buy.garmin.com/en-US/US/p/10997 & https://www.thisisant.com/
