August Home Smart Lock with Keypad – Keyless Entry via Smartphone or Codes – Silver – Secure Your Home with Smart Access Control for Front Doors & Apartments

So everything works as intended. However like other people have mentioned, the auto-unlock feature is a little quirky, but it's not because of the lock, but more due to my phone and its operating system and how it handles connections (bluetooth and WiFi specifically). So the auto-unlock feature works flawlessly if I have my phone in my hand and the screen is on, and that's because when the screen is on, the phone actively detects bluetooth and WiFi connections (it has to detect your home WiFi connection so that it knows you're actually "home", for security purposes). Since I'm typically on my phone, that works well. If my phone is in my pocket, the bluetooth and WiFi connections are detected passively (this is how it works on all Android phones to save battery power), and so the detection of the WiFi network switch happens slightly slower, but still reliably works about 80% of the time. Sometimes, I'll reach my door and it's still locked and the second I go to reach for my phone, my phone passively detects the WiFi (or is in the process thereof), and the door unlocks. The other thing people may not be aware of is that the app is watching for you to return to your "neighborhood" which is about 200 meters from your door. That said, this means that the auto-unlock feature typically doesn't engage if you go somewhere close, like your mailbox or to put the trash out for example. You've gotta travel outside of the 200 meter region that represents where your place is. The app works reliable to auto-unlock my door whenever I leave that 200 meter circle. On the way back the app, as I approach my neighborhood, the app shows up in my notifications with the auto-unlock feature engaged. By the time I park, and walk towards the door, it unlocks 9 out of 10 cases before I reach the door, and 1 out of 10 cases as I reach the door. If my phone is in my hand, this happens in 10 out of 10 cases. If my phone is in my pocket, roughly 9 out of 10 cases as I approach the door, 1 time out of 10 it'll open as I reach the door, or within a second or two after I reach the door (when my phone connects to my home WiFi and the app detects that scenario occurring). I have a Samsung Galaxy S9+ for reference. My son who has an iPhone XR has the same experience as I do with the auto-unlock on his phone. I'd say his works even more reliably than mine does. This lock is definitely worth the purchase. It works well, is easy to install, and now when I leave, it locks the door behind me too which I love.
