5.0 out of 5 stars Pros/Cons from a geek, early adopter, and smart-home enthusiast!
Reviewed in the United States 🇺🇸 on October 19, 2017
Wanted to give a few thoughts about my recently purchased August smart lock. For background, I’m running this lock in a decidedly “smart” house. Two Nest thermostats, a harmony hub, myQ garage, and 25+ LIFX connected lights.

+ Super brain-dead easy install. Took less than 10 minutes with just a philips head screwdriver. The video walkthrough on the app makes it really hard to mess up.
+ HomeKit integration is badass, and works flawlessly for me. There’s something soo cool tellling Siri on my cellular Apple Watch to lock/unlock the door, and it’s done. This works from inside/outside my house, on wifi, cellular, doesn’t matter.
+ Auto-locking is customizeable and works great. Don’t have to fish my key out to lock the door every time I take the puppers outside for a potty break.

* Doorsense, the little nubbin that you attach to your door frame that tells you if the door is open/ajar, was really easy to install and setup. So far though, doesn’t seem like a must-have feature.
* Remote unlock with the included August Connect works fine, no issues so far. Takes a little bit longer than I’d like to actually connect to the lock when I’m out and about though.
* a little bit pricey at $279 retail, but c’est la vie, yolo, and fomo

- Auto-Unlock is finicky and unpredictable. It doesn’t work when you expect it to. This is the only reason why I gave it 3-stars instead of 5. The way it’s supposed to work is that you set your home location in the august app, and this puts a 200-meter radius around that spot (about a couple city blocks). When you (and your phone) leave this area, the lock enters “auto-unlock” mode, and is supposed to automatically unlock the next time you enter Bluetooth range (maybe 15-20 feet) or seemingly whenever you hop on to the same wifi network as the lock. Obviously, you have to keep Bluetooth on, and not force-close the app for this to work. The app will even send you a push notification when it detects that you’ve left your home area, and that the lock has entered auto-unlock mode. The problem is that it just doesn’t work 100% of the time. I’ve had instances where I did exactly as I was supposed to (left home area, got push notification saying lock was in auto-unlock mode, kept Bluetooth on and app active), and the lock doesn’t unlock even though I’m literally standing on the other side of the door. I’ve also had times when the lock won’t detect that I’ve left my neighborhood, and thus never enters auto-unlock mode in the first place. No rhyme or reason to it. On twitter, August says they’re constantly tweaking the algorithm of auto-unlock, so there’s hope that this will get better. Also, the home radius should be way less than 200-meters! I don’t live in a mega-mansion/ranch, and I shouldn’t have to wander a couple city blocks for the lock to know I’m not at home.

Other random thought(s):
* How badass would it be if the lock could use my cellular Apple Watch to auto-unlock??

TLDR: Easy install, auto-locking is awesome and customizable, HomeKit integration is sweet, but auto-unlocking algorithm needs more time in the oven. If “hey Siri unlock the door” from my Apple Watch didn’t work as well as it did, I’d probably return the lock.

*update 11/8/17* - upgrading to 3.5 stars
- Picked up the new iPhone X last week. Absolutely love this phone. Can you imagine if August put FaceID in their lock?? The future will be amazing (and a little creepy). Oh yeah, the iPhone X works fine with the August lock, no issues at all.
- August issued a firmware update to the lock about a week ago (1.5.21). Auto-unlock feels like it is getting better at recognizing when I’ve arrived home. Still not 100% reliable. It sometimes takes too long for the lock to recognize that I’m standing outside (sometimes up to 5-10s). But the frequency of it working as it should is going up! Good job August, keep it coming!
- If you have an iPhone, add the August widget to your lock screen. This gives you one-touch lock/unlock capability. And if you have the new iPhone X and Face ID, your phone will automatically unlock for you as soon as you look at it, so unlocking your august lock is one swipe + one tap away.
- Not having to fish my key out every time I leave/come home truly is a luxury. Auto-locking works perfectly every time. And even with the ongoing auto-unlock finickiness, I feel confident enough in the lock that I removed my house key from my key ring (only the car key and mail key left!). And pulling out my phone and hitting unlock on the widget screen is still faster and more convenient than fumbling with a physical key in the dark.

*update 5/25/18* - upgrading to 4.5 stars
- August keeps improving the lock. Recently issued an update that makes remote connection almost instantaneous now. You don't have to manually connect to the August Connect any more either - it just does it automatically. Very cool.
- Auto-unlock continues to improve. Still wish it would enter auto-away mode much sooner! One little quirk that I did not mention in the original review is that even when I enter the house from the garage on the other side of my home, the August Lock will auto-unlock. It does this reliably and consistently, even though I don't really want it to. I believe this is called out in the support documents, so it's not really a bug. It doesn't really bother me at all though, since it will always auto-lock itself after a few minutes anyway. Probably just uses the battery a little bit more is all.
- Guest access keys work great so far!
- Speaking of battery, I get about 3 months of use out of 4xAAs. I switched to some rechargeable eneloops, and seem to be getting a bit more use this time.

*update 6/25/18* - upgrading to 5 stars
- August updated the lock firmware again, and this time, it allows me to use the iphone widget to directly unlock the lock. Before, hitting the unlock button on the widget would take you to the app, and you had to tap the screen again to unlock the lock. It's so much faster now!
- Still wish the away-mode radius could be smaller, but maybe it'll get there soon with how regularly August seems to be improving the lock!
- Having had the lock for the better part of a year, I feel confident enough about it to recommend it to family now. Friends and family who have seen/used it have also commented on how much easier it is to use than a regular key.

5.0 out of 5 stars Auto-unlock/lock, Digital Guest keys, full-Manual backup + rock solid Homekit integration!
Reviewed in the United States 🇺🇸 on March 17, 2019
My top priories while searching for a smart lock for the 1st time were:
- Full-automation for locking/unlocking the door
- Visibility into the status of the door and ability to lock/unlock it from anywhere at anytime
- Ability to easily give visitors or contractors access, while also managing and restricting that access
However, my WIFE’s one and only concern was having a fully-MANUAL backup option that she could easily use if issues were ever to occur or she couldn’t get it to work lol.

This lock has somehow managed to meet BOTH of our requirements in a single package, and more importantly, helped my wife COMpletely overcome her general fear of these types of devices!

The primary reasons I bought this smart lock over the others I reviewed including the: Kwikset Kevo 2nd Gen, and Ultraloq UL3 are:

- Ability to maintain existing external lock & use my existing key to manually open the door whenever needed:
—This is not only convenient it’s also more secure. Because this lock sits on the back of the door, no one can tell from the outside that you even have a smart lock therefore negating the possibly of people trying to “hack” it or anything else.
— Neither the Kevo or Ultraloq can claim this as both make it clearly evident from outside that you have a smart lock.

- Auto Un-Lock Function: You can set up a geo-fence around your home that will automatically lock the door when you exit that area, and automatically unlock it when you come home. This seems like a small thing but in reality it has completely changed how we interact with our home.
— I no longer have to fumble with keys while holding groceries and my backpack, I also don’t have to worry about wonder if I locked the door when I’m in a rush on my way to work in the morning, I just close the door and walk away knowing the lock will do it’s thing!

- Ability to send virtual “Guest” keys to visitors and contractors with user-specified durations and auto-expiration:
—The KwikSet Kevo did have the option to send guest eKeys, but they were limited to 24hrs max and not available on all devices. Ultraloq did not offer this capability at all.

- Ease of use and install + HomeKit integration: The installation of this lock took no more than 15 minutes start to finish. That is including setting up the Wi-Fi connect module, and connecting it HomeKit.
— At the time of review (Dec, 18) The Ultraloq did not have ANY kind of smart home integration ability, while the Kevo sis have Alexa just not Homekit or Google Home. Problem is, to use with either one you need to buy a separate $100 hub that will be used for NOTHING else!

CONS/Potential Future Improvements:
There are a few shortcomings/enhancements I would like to see addressed in a version 3:

- Additional unlocking options besides auto-unlock or manually clicking “Unlock” from within the app.
— One thing both of the other locks I looked at had going for them was multiple ways to unlock besides the core Bluetooth functionality. Having the ability to unlock my door by maybe tapping my phone 3 times on it, or by using an “at-home” setting that works like the regular auto-unlock but does so repeatedly would be very nice.
— It is a bit of a pain to have to pull out my phone or watch because the door has locked while I was going in/out the garage working on something.

- Integration of the Wi-Fi functionality into the lock itself instead of needing a separate connect module.
— I understand August’ reasoning as a Wi-Fi module would add heft and also drain battery life much quicker but at least giving users the option would be nice. Maybe add a rechargeable lithium-ion battery to both address the Wi-Fi power consumption issues and negate the need to replace AA batteries all together.

- Ability to have multiple locks set to auto-unlock upon arriving at home: Again I understand the reasoning but sometimes I’m bringing different items that I can’t fit through the garage door and I need to go through the front, having both unlock for a set period of time would make things that much easier.

- Always show a “Battery Life Remaining” indicator in the app instead of waiting till they are almost dead and saying: “batteries are low and need to be replaced.”

- Lastly, and one of my only true concerns, streamline the Guest sign-up process!!
— The flexibility of being able to send digital keys to guests is wonderful, however, making those guest download the August app AND create and account just to use that digital key is a bit much! It almost defeats the “ease of use” principle in the 1st place...
— Instead of this, I would expect to see a streamlined process that brings users to a simply laid out HTML5 webpage explaining the sign-up process and how to use the key. It would then ask them for permission to query the device for its unique Bluetooth signature in order to link the phone to the lock, no August acct required. (I can examine technically how this would work but all you non-engineers out there would gloss over :) so August contact me if you want to know!)

Overall I am quite pleased with this device, in fact I liked it so much I bought a used 1st gen one for my garage door too! All of the above functions have so far made for a seamless experience and although there are some small issues, they are irritations at best.

If you are looking for an all-encompassing smart lock with rock solid Homekit integration, (and your still reading my review at this point!), you have found it. Don’t add it to a list, don’t read any more reviews, just go ahead and buy this thing now: your wife will thank you!
