A feature like “Ring to open” for the smart lock.
Press the lock button twice to enable it. If the lock gets a bluetooth connection with your phone in the next 5 minutes (2 minutes after pressing it), it automatically opens.
When I am bringing out some garbage, going into the cellar, just grabbing something from my car or visiting the store 50 meters from my home, I can enable “Ring to open” and get back into the house with the opener. But then I am stuck in front of my door, because I haven’t left the geofence and thus there will not be any automatically unlocking.
This could also be realised with this feature request (but it won’t be automatically as described here):
