Anyone Using Libre2 with Juggluco?

Greetings from China!

Libre 2 works great with juggluco+xdrip to send data to my nightscout pages.

But after 10 days, the readings became higher than it actually was.

The question is, has anyone successfully calibrated Libre 2?

Juggluco website states that they don’t support calibration, but is there a way to bypass it?
