Do you have to have the app running on your smart phone in order to unlock the door?
Do you have to have the app running on your phone every time you open the door, or can you have it in your pocket?
No, if you set Autounlock to ON in the smartlock app settings on your phone, when ever you return home after the lock has been locked, it will unlock once you (your phone) are inside the geo-fence that can be set in the settings.
You DO need to run the app to open the door "manually".. by pressing the button in the app.
Hope this helps
