Missing device in mobile



I am trying to get automatic presence to work with my iPhone. I can’t get Homey to recognize when I am leaving and entering home. I don’t know what is the reason, but I have enabled “home detection” on my phone and also tried to setup flows to update the status.

But what puzzles me is that when I want to make a flow where I use mobile as tricker then I can’t find my phone in the list - the list is empty.

Should I set up my phone in some other way or any inputs?
