Upload to a Nightscout server.
In most cases you can also use the webserver in Juggluco or juggluco-server, only AAPS and NSclient refuse to work when not connected to cgm-remote-monitor. The web server in Juggluco also gives amounts in the form of Nightscout treatments (https://www.juggluco.nl/Juggluco/webserver.html), the uploader only uploads glucose values.
All stream values are uploaded to the Nightscout server at the moment they arrive. When multiple sensor are used, all values of all sensors are uploaded. Some Garmin watch apps/faces/widgets assume that the values are space 5 minutes apart. When they receive glucose values one minute apart, they will only show the last fifth of the curve. For that reason, the webserver incorporated in Juggluco spaces the values 5 minutes apart, except when "interval=secs" is set to a lower value.
URL: the url should be in the form of https://hostname:port for example, https://myname.herokuapp.com:6789
Active: Turn on uploader
Resend data: Upload all data again to the Nightscout server
Send now: Normally data is immediately send when it arrives from the sensor or a mirror connection. Press on this button when for some reason a previous attempt failed.
The WearOS version Juggluco 4.15.0 and later can also upload glucose values to Nightscout. In nearly all cases you can better send them via a Juggluco version on a phone or tablet or via Juggluco server on a computer. It will drain the battery, especially when it is unable to contact the Nightscout server, so you can better turn Active off when there is no reliable connection.
