As said: Presence detection does not work most of the the time.
I see in the app that I came home twice a day, while I never left.
I walk with my dog in the forest, but according to the app I'm home.
It switches to Away and says "because of inactivity" (don't know why/how).
When I do come home, my iPhone always connects immediately with my WiFi (yes, same network for all apps and devices).
The golden tip would be appreciated .
