Yes. 
 
 When the built-in sensor of eufy smart lock detects that your door is in a fixed closed position, it will trigger Smart Lock to automatically lock your door. You can set a time period for the Auto-Lock function. But it does not offer an auto-unlock feature to unlock the door when it sees that you&#39;ve come home based on your phone&#39;s location data.
 
Here are steps to enable it in eufy App: Click the Setting button in the smart lock device tab &gt; Lock Settings &gt; Auto Lock &gt; Enable the Auto-lock.
