Eversense CGM integration via NotificationListenerService

[BernhardRo]

Hello, would it be possible to extend your UiBasedCollector to work with Eversense as well? Eversense also implements a permanent notification, which can be identified by "com.senseonics.gen12androidapp". The current glucose value is then available as string in "notification.tickerText"
Right now, a patch for the Eversense App exists to access the data, but with every update of the App, it gets more and more critical to patch it!

Can I ask a question for my benefit to see if I can personally help or not?

The UI based collector, by default, does no backfill. So, if you walk away from your phone, when you come back, you will have missing readings in xDrip.
There is an exception for some particular devices like Dexcom transmitters. But, for others, that's the limitation.

Can you tell me if the existing Eversense hardware database in xDrip offers backfill or not?

My second question is about the app notification you have mentioned.
Can you post a screenshot of the notification?
What is the name of the app in the play store so that I can install for testing?
Does the app produce a unique notification for each reading showing the reading?

[BernhardRo]

Wow, that was a fast reaction!

The solution we have right now supports backfilling. But as I mentioned, I am not sure if we will be able to patch future versions as well. So to have an alternative, easy way of access (which works out of the box with the original app) would be a huge advantage.
The app can be found here: https://play.google.com/store/apps/details?id=com.senseonics.gen12androidapp
There is also a specific US version, but that not accessible from Europe (but I would have the apk)
I have tested it with https://github.com/pilot51/voicenotify (modified) and I got readings probably every 10sec - even though the value itself is only updated every 5min.
This is how it looks like:

Will you be able to do a test for us?
If you install the official app that you have access to, and set xDrip to the companion app hardware data source, does it not get readings?

[BernhardRo]

Up to now, I do not get any values.

[Navid200]

Can you post a screenshot of the classic status page?

[BernhardRo]

I have downloaded and installed xDrip from here: https://jamorham.github.io/#xdrip-plus (~2h ago) and not sure, if this is the correct version.
At least, I do not get values.
I updated the permissions as it requires access to the notifications. This was not directly possible on my Pixel 6a with Android 14. Instead, I had to allow restricted settings before, see https://support.google.com/android/answer/12623953?hl=en
I am not able to compile xDrip on my machine, otherwise I would help with it. But when I take a look at this voicenotify with the Debugger, it looks like this:

[BernhardRo]

Can I support you further? I can imagine that it is very hard to debug something which is not local available.
By the way, the settings regarding notification access are looking like this

It is strange that something is grayed out.

[Navid200]

Can you enable detail logs? Although, I am not sure there are many.
Go to xDrip Settings, Less common settings, Extra Logging Settings, Extra tags for logging.
Enter the following.
UiBasedCollector:v

Enable companion app.
Let it run for 5-10 minutes.
Do you see any new logs?

[jamorham]

@BernhardRo Please try the nightly B version just released some minutes ago. You may need to download it manually. See if that works?

[BernhardRo]

Yes, this works! Great job, thank you!
I need to find out if the US app has the same identifier. If so - fine! If not, than an additional identify is needed for it

[BernhardRo]

OK, I have checked it: the US version has the identifier "com.senseonics.androidapp". So this "gen12" of the EU version is missing. I do not have a running version available, but at least I know who to ask for testing!

[jamorham]

Yes this should be possible

[BernhardRo]

Have you already been able to extend the NotificationListenerService to the US version as well, so to notifications from "com.senseonics.androidapp"?

[4RK4N]

been testing that as well. works good so far. sometimes it gets a bit out of sync like grabbing a value from the notification 30 seconds before a new one comes in so you then have an old value shown as new. but then it syncs itself quickly again by pushing out another value on notification change. i have now 120% of bg values grabbed per day which means it doing a bit too often but most of the time it works pretty well. good job.

good thing aaps has its smoothing plugins sorted out by now. without it it wouldnt be usable for looping.

question 1: since we have settings for the settings of everything can we have some settings to configure the xdrip smoothing algorithm and its weights? curently xdrips smoothing is way too weak to produce loopable values and needs another smoothing instance somewhere.

question 2: as you can see on BernhardRo's screenshot the transmitter battery value is also displayed in that eversense notification and aaps can display such a battery value now in the latest version. but the xdrip code doesnt look like its grabbing the battery value right now. can that be done?
