My living room is In 2nd floor in my town house. I hated going down always to open the front door when any guests come. I installed nest video cam and Google home hub to see who is at the front door. Since I have Google eco system, I wanted a product to unlock my front door with voice control. After a little bit of research, looks like august is the only option on the market which can integrate with Google assistant to unlock the door ( with security pin ) . I am happy with this product. Works as expected. I am now able to unlock my front door with voice command ( with Google home hub and mobile as well) . Only problem I noticed is auto unlocking with Android phone when I come close to front door. It's not consistent .
