let me know what sensors were used in an activity.
You can find the list of sensors used in an actvity, in JSON format, with the help of the following URL (replace the numeric activity ID with the ID of your activity found in the address line of the activity page):
connect.garmin.com/modern/proxy/activity-service/activity/123456789123
Then search in the results for the section sensors, it will show something in this form:
{sku: "006-B3126-00", softwareVersion: 7} {sku: "006-B3126-00", localDeviceType: "BAROMETER", softwareVersion: 7} {sku: "006-B3750-00", localDeviceType: "GPS", softwareVersion: 2.6} {localDeviceType: "ACCELEROMETER", softwareVersion: 249.56} {localDeviceType: "WHR", softwareVersion: 3.32} {sku: "006-B3127-00", localDeviceType: "SENSOR_HUB", softwareVersion: 1.4}
If you have no viewer for "beautifying" the JSON output, you can use for example the online JSON viewer.
Let me select gps elevation afterwards. With a push of a button.
That is already possible, since a long time (a few years?). Enable Elevation Corrections at the concerned activity (see the option on the right side of the activity screen, just below the watch photo)
Not sure about Elevation Correction button.
I tried it many times and it showed elevation data taken from the map or from other users, not from MY gps.
The only sure way I know is to export GPX file and re-upload it so it doesn't contain Baro-data
