Sensors
Here is a lists sensors that can be used with Juggluco. See also https://www.juggluco.nl/Juggluco/sensors. All sensors, except Libre 0, can be configured in the phone version of Juggluco to directly connect with a Wear OS watch, so you can receive glucose values on your watch, while leaving your phone home.
The first Freestyle Libre sensor that can only be scanned via NFC. Juggluco can scan and activate these sensors. They are only partly supported. The values can be displayed, saved and send to Libreview, but for statistics screen in Juggluco the values received via Bluetooth are used. The web server can also be used to receive the scans and history values, but they are not send by the glucose broadcasts or used for Nightscout.
The 14 days US Freestyle Libre sensor can be used with Juggluco.
To use it, scan the sensor.
There are different variants of Freestyle Libre 2 sensors. All of them are fully supported by Juggluco. They can be activated, scanned and the glucose values can be received via Bluetooth.
Scan the sensor via NFC to use it. You need to force stop the app previously used with sensor and turn off Freestyle reader.
Also fully supported. Both the European and the USA variant.
If you want to take over a sensor from Abbott's Libre 3 app or be able to return the connection of the sensor to Abbott's app, you need to enter your Libreview account information in Left menu→Settings→Exchange data→ Libreview and press "Get Account ID"→From Libreview. If you only want to use a sensor with Juggluco, you can enter an arbitrary number under "Get Account ID". Hereafter you need to scan the Libre 3 sensor. You can only effectively scan a Libre 3 sensor when it was activated with the same Libreview account ID as when it is later scanned.
You always need to make sure that the app previously used with the sensor isn't running.
Juggluco works with Sibionics GS1Sb. Before Juggluco 9.3.0, it only worked with a Chinese market variant. Juggluco 9.3.0 and later can also be used with the European variant and Hematonix.
To use a sensor, press in Juggluco left menu→Photo and scan the data matrix on the package.
Force stop the app previously used with the sensor.
There are different types of Sibionics 2 sensors and Juggluco is reported to work with some of them. A photo of the package of a transmitter and sensors that are reported to work is displayed below:
Works with Dexcom G7.
You can return back to the original app by terminating the sensor in Juggluco (left menu→Sensor→Terminate) and starting the other app (and entering the pin code).
To use a Dexcom G7 with Juggluco, you scan the data matrix on the applicator with left menu→Photo. Put other used Dexcom sensors out of Bluetooth reach and turn off apps and devices that were previously connected with the sensor or turn off Bluetooth of the previous device.
You have to agree to pair the sensor and if you are too late you have to wait another 5 minutes. So keep the display on.
When directly connected with Samsung Galaxy Watch 4 or 7 you don't need to agree to pair the sensor. Something Samsung specific?
If you want to directly connect the sensor with a WearOS watch, you can also turn on left menu→Watch→WearOS config→Direct sensor-watch connection, before scanning the applicator data matrix. Switching between devices is difficult for this sensor.
With Dexcom ONE+ it works exactly the same way as with Dexcom G7.
Sensor works with Juggluco 10.2.0 and higher. To use it scan the data matrix on the blue cap with left menu→Photo and enter the PIN when asked. As with all sensors other apps used with the sensor should be force stopped. The phone version of Juggluco worked well with the sensor when running on arm64 Android 8 and Android 14. Under arm32 it did work well under an old Android 4.2 phone on which an Android 13 custom rom was placed, but it didn’t work on an Android 5 phone still running Android 5.
The WearOS version worked well with this sensor when running on Samsung Galaxy Watch 4 and 7. It didn’t work on a TicWatch Pro. It was very difficult to enter the pin because the keypad was closed before I had entered the pin or the enter-key or even before starting typing. I managed a few time to enter the whole pin including the enter-key, but even then it didn’t work. Other sensors work well with the TicWatch Pro.
The main advantage of the Accu-Chek SmartGuide sensor is that you can get a free test exemplar in some countries. The main disadvantages are its gigantic size (even larger than Libre 2), the need to be calibrated and even then it is less accurate than Libre 3.
Another plus point is that when you have a phone or watch to which the sensor can connect, the Bluetooth connection is very stable. Which is also needed because it sends only 1 value every 5 minute. Missing one means that you are looking at a 10 minutes old value (a gap that will be filled in later).
