Garmin provides wearables, sport watches, and hybrids.
The data for the wearables comes from Garmin Connect (Wellness), such as your step summary, detected activities, sleep, etc. from devices such as Vivofit.
The data for the sport watches is available under Garmin Connect (Sports) which has the detailed data to better analyze your activities.
The hybrid devices will have data from both services and we recommend using both for the best data for your analysis.
Garmin Connect is federated and has their services both behind https://connect.garmin.com/ and https://connect.garmin.cn/. If you access your data via the https://connect.garmin.cn/ endpoint, please use the [China] denoted Garmin Connect sources, otherwise you should use the default.
Garmin has made changes to their API program in the summer of 2016 which provides you with better security and flexibility and as a consequence, some of our features are impacted.
Garmin (and other services) do post processing of the data that they send us. As a consequence of this, sometimes the durations and various metrics will not match exactly because of this.
We use Garmin’s Push API which means that when your Garmin device syncs with Garmin, we receive it shortly afterwards. Some of your activities may originate in other services such as Zwift or SufferFest which due to contractual obligations, they do not send such activities to us. If your data originates from another party, we recommend that you use an alternative sound for that data.
For Garmin Connect, we get immediately notified whenever you sync or add a new activity on their end, and thus, the sync button usually does not find anything.
Garmin Connect only starts collecting data from the moment you start using FitnessSyncer. For Garmin Connect (Wellness), Pro users can request historic syncs, but this only covers the previous 30 days of data.
If this is still happening, you may need to delete tokens from Garmin Connect. To do so:
If you are still experiencing problems, please contact us.
If you use the ANT stick and have the .FIT files on your hard drive, you can use the FitnessSyncer Uploader to upload that data into your Notebook.
Otherwise, you can go to Garmin Connect and download a summary CSV:
Garmin Connect samples the sleep and can send us a couple updates of the sleep records before it is finalized, but are sometimes indistinguishable between the completed and incomplete sleeps. Depending on when the sync occurs, it is possible that the sleep sent was incomplete. There currently is not a workaround on this.
Garmin Connect (Wellness) only permits the last 30 days for historic syncs. This usually happens by default when you sign up.
For Garmin Connect (Sports), you may need to try to reauthenticate the connection to make it work.
