The door has been opened by Proximity when I was walking home, what can I do?

Proximity is programmed to detect whether you're walking or in a vehicle (to the extent possible based on iOS/Android data). If Proximity doesn't have enough information and/or its reliability is low, it may occasionally automatically open the door as well.

To prevent this from happening, you must activateThe “Physical Activity” permission for the HOMYHUB app. This permission is required to detect whether you're walking or driving home.
