Is there a bluetooth powered door lock?

Dan has an aunt who lives a reclusive life and there are times she can't get up to open her own door. So is there a remote option that will allow her to open the door? Leo says sure. But what she will want is a camera and monitor so she can see who's at the door before she opens it. But that will require wifi. Schlage makes one that opens via bluetooth. Kwikset is the first company to do this as well. You can even get one that works with Amazon Echo. That's cool. But you need to make sure the company updates the bluetooth security regularly. Since you'll want a local alarm company to install it, it may be a good idea to talk to them because they will now what the latest state of the art is.
