How to read data from notification with customView

I am trying to read data ("178 in the screenshot) from a notification that contains no text, no title but a customView (“android.contains.customView” is true).

Is this possible on Android?

this sensor will get all the data available https://companion.home-assistant.io/docs/core/sensors#last-notification

I cannot get any data from this specific notification via the sensor:

then i dont believe the app will be able to get any data, I dont even know if Tasker can but if Tasker can then there is a good chance we can.

I did not try it myself (yet) but on native Android-level I think it is possible to get RemoteViews via reflection. Maybe we can analyze the custom view from there on.

How would I pass data from native Android code to Home Assistant (Companion)?

submit a code change to the app to support the feature you want?

Alright. Maybe something else knows a simpler way of reading notification data from a custom view, otherwise I will follow your lead and try my hand at a pull request. Thanks so far and all the best!
