How to use a sensor with Juggluco? In all cases you need to force stop the apps that previous connected with the sensor and somehow stop the Freestyle Reader.
Scan the sensor at least two times by holding the NFC unit in the phone against the sensor.
The same applies to Libre 2+. Juggluco can be used and can activate all Libre 2 and Libre 2+ sensors.
Goto left menu→Settings→Exchange data→Libreview. If you want to use a sensor with both Abbotts Libre 3 app and Juggluco, you need to enter the same account information as in Abbotts Libre 3 app. Here after you need to press “Get Account ID”→”From Libreview”.
Juggluco can only take over a sensor that was activated with Abbotts Libre 3 app (https://play.google.com/store/apps/details?id=com.freestylelibre3.app.us) that at that time was associated with the same Libreview account as entered in Juggluco.
Juggluco can not take over a sensor activated with FreeStyle Libre 3 reader or the Unified Libre app (https://play.google.com/store/apps/details?id=com.abbott.adc.freestyle.libre.us).
If you only want to use the sensor with Juggluco, you can check “manual” under “Get Account ID” and enter an arbitrary number and activate the sensor with Juggluco.
If you later want to be able to later use Abbotts Libre 3 app, you need to receive the Account ID from Libreview before activating the sensor.

The same applies to Libre 3+.
To use a Sibionics sensor with Juggluco you need to scan the data matrix on the sensor package with left menu→Photo. Thereafter, you have to specify what sensor you are using: EU, Hematonix, Chinese or Sibionics 2/Split/Light. The application ID of the official app for that sensor is also displayed.
Scan the data matrix on the applicator with left menu→Photo. Keep the display on so that you don’t lose the opportunity to agree to pair the sensor. If you miss it, you have to wait another 5 minutes.
Scan the data matrix on the blue cap of the applicator. When asked, enter the PIN code also displayed on the blue cap.
It is uncertain whether you can use an Accu-Chek SmartGuide sensor with Juggluco that wasn’t already used with the official app.
To use a CareSens Air sensor with Juggluco scan the data matrix on the inner package with left menu→Photo.
A difficulty with CareSense Air sensors is that you can change only one time the device (phone or watch) to which the sensor is connected. When you switch back it doesn’t work. It does work again when you switch back to that second device.
So if you connected the sensor to a phone you can best first connect the sensor to Juggluco on that same phone. But when you start a sensor with Juggluco and you want to connect the sensor to a WearOS watch, you can better immediately set left menu→Watch→WearOS config→Direct sensor-watch connection. If you don’t like it, you can than always switch to connecting to the phone.
The official app has the strange feature that values are modified afterward. At a particular time it receives a glucose measurement and shows that value, but every 5 minutes thereafter (for 30 minutes) besides showing a new value, it changes this previous glucose value. You can see it yourself by saving the glucose values every 5 minutes in the official app.
Juggluco places the immediately shown value in the stream values and the afterward modified values in the History values. So by looking at the Stream values, you can see what the value was at the moment itself. By looking at the History values, you see the value as modified afterward.
In my 8-day experience with this sensor, the glucose values were nearly as accurate as Libre3. The main disadvantage is the glue used to attach the sensor: It doesn’t hold for more than 8 days and after the sensor fell off, no glue remained attached to the skin as is the case with other sensors. They have tried to solve this issue by supplying a large sticker that can be attached on top of the sensor and the surrounding skin, but who will want to use that?
