August HomeSmart Lock - Keyless Home Entry with Your Smartphone - Dark Gray

If you live alone and only have one door, this smart lock is all you need. It locks the door behind you when you leave, it unlocks the door for you when you arrive back home, and finally, it locks the door again a couple of minutes after you enter. What else do you need? I really don’t see the point in spending the extra $70 for the wi-fi adapter. I got this one on sale for under a hundred bucks on Amazon and especially compared to all the alternatives in the two to three hundred dollar range, it is a real bargain!Installation is a breeze. Total time to physically install the lock is 5 minutes. It takes longer to get the Android app configured. I did not install the “door sense” feature as I am not sure it is needed. Again, I live alone and am pretty good at closing the door behind me. I may change my mind at a later time and will update this review if I do.Unlike some other reviewers, I have not had a problem with the Bluetooth connectivity. Using the android app to manually open and close the lock, I find the Bluetooth range to be at least 30 feet from the lock both from inside and outside of my front door. I can even unlock the front door with the app from my bedroom which is upstairs and on the opposite side of the house. I also don’t find it necessary to have wi-fi turned on on my phone as the instructions recommend (I have an unlimited data plan so I usually leave wi-fi turned off to save battery life). Still, the lock seems to know I’m home as I am parking in my garage as I get a notification on my phone. Some reviewers have complained about the Bluetooth being slow and lagging, but I haven’t noticed that. Maybe it’s because I have a detached garaged and it takes me a while to get to my front door.My existing door hardware is a dark bronze color, and the dark gray August Smart Lock 3rd Gen is a pretty good match so it looks smart and yet unobtrusive on my door. The fact that low-tech people can still use a key to enter and manually lock or unlock the door on the inside is a big plus. Overall, two thumbs up and five stars for the August Smart Lock 3rd Gen!

Bought this lock because I have 4 children that do not know how to lock a door and the front door was many times unlocked when I woke up in the morning or came back from work. Someone could easily walk into my house and steal us blind or murder us in our sleep. Buying the lock with a bridge opens up a whole host of options with a minimal cost (less than $50). I can check the status of the lock at all times (I travel the country frequently and have no problem checking the status). I can open the lock from anywhere if someone is at the door that I want to let in. I have to lock set up to close 10 min after the door is shut. Works like a champ. The auto unlock also works without any problem is you have the bridge. The auto unlock feature works by recognizing when you leave the house by 200 M and will auto-unlock when you come back within 200M. All of my kids were invited as guests and use the app to get in/out of the house without a hitch. I can see where if you do not have the bridge there may be issues with getting the blue-tooth to work exclusively. I have attached a couple of pictures to show where I have the bridge in location to the lock. The app says the blue-tooth connection is weak with the bridge, but so far any communication between the bridge and the lock has worked flawlessly. Overall this lock has added a peace of mind to me as I have worried about this situation for at least a year. Given some of the negative comments I have read, I was hesitant to buy. However, I think all of the problems people have is completely remedied if they buy the bridge with the lock. Too bad the lock was not designed to just do what the bridge does, but I think it was done this way to conserve battery life. The bridge does the heavy lifting and can do so because it is plugged in. The lock can stay in a "low power" bluetooth mode to conserve battery life. I highly recommend this lock if you are faced with my situation.

I bought this lock as a stand-alone item (not tied into my network with the optional network interface). It works as expected and I would purchase it again.Notes:1) Physical installation: Simple and straightforward - takes about 20 min. If you can operate a screw driver and follow directions, you can do this installation. Start by installing the app on your smart phone and fire the app up. That will walk you through the process of doing the physical installation of the hardware.2) Minor installation issue: One of the side wings that keeps the lock unit on the door keeps drifting open. I keep pushing it back in - the unit has never actually fallen down / off, but this is slightly annoying.3) Installation note: As advertised, this product does not interfere with the use or appearance of the outside lock or your existing key.4) Unlocking: I have it set up to unlock the door when I get back within range of the house. Around 2/3 of the time as I'm walking up to the door from my car my phone will vibrate and I hear the door lock unlock. The other 1/3 of the time I either have to wait a few minutes or pull out the phone, open the app and unlock the lock. (I have an iPhone 6. However, cell service stops working about 4 blocks from my house and "comes back" via WiFi connection when I arrive home.) Once the app realizes that I'm back home, it always opens the door.5) Locking: I found the automatic locking via a timer to not work for me because I go through this door a lot when I'm home. You have to be a good solid block away before "away" mode is triggered. I expected this behavior and I have just been using my house key to lock the door when I leave. I haven't tried telling Siri to lock or unlock my door.I would give this product 5 stars if it would always unlock the door when I come home and if the attachment wings would stay put. I still rate this product as a 90-95%, not the 80% that a 4 star rating implies.
