Entschuldigung dass ich kein deutsch spreche aber  
We know now that on the following devices the homey app does not work:  
Nokia 7 plus, android 9  
Huawei Mate 20 pro, android 9  
Samsung S8 android 9  
Samsung S9 plus, android 9

So I would make the assumption that:  
The Homey-app does not work on Android 9.

Like you all already mentioned, there are apps that do work on android 9, like Tado and in my case Tasker.

(Besides that all, then there are the manufacturer specific battery saver thingies. In my experience is especially Nokia horrendous in this regard. (I got my nokia on track by following: [https://dontkillmyapp.com/nokia](https://dontkillmyapp.com/nokia) but warning, this is not for the faint of heart.)  
But on that website samsung and huawei are listed as well.)

Could you guys agree on that?  
Or are there devices with android 9 that do have a working homey-app? (presence detection that is)
