The August Wi-Fi Smart Lock (4th Generation) and August app allows you to remotely lock or unlock your door, check door status, grant virtual guest keys and always know who’s coming and going. Connected out of the box with built in Wi-Fi, the August Wi-Fi Smart Lock is easy to install and attaches to your existing deadbolt so you can keep your original keys.
UPGRADE YOUR EXISTING DEADBOLT: August smart locks fit on the inside of your door, making your regular deadbolt smarter, more secure and way more convenient. Keep your keys just in case (but you won’t need them).
GRANT ACCESS WITH THE AUGUST APP: Forget key copying. Quickly and easily share permanent, scheduled or temporary access to your home with friends, family and other people you trust, and never put a key under the doormat again.
EASY TO INSTALL ON ANY DOOR: Even if you’re not so handy, installation only takes about 10 minutes. August locks fit perfectly over most single cylinder deadbolts and aren’t much bigger than your original thumbturn.
AUTO-LOCKS AND UNLOCKS: August Wi-Fi Smart Lock is able to Auto-Unlock as you get home for totally hands-free unlocking (optional). With Auto-Lock and DoorSense, your home automatically secures once your door is closed, or after a set amount of time.

FACE OR FINGERPRINT ID FOR EXTRA SECURITY: Use your phone’s biometric recognition for two-factor authentication (optional).

Easy to install and nice enhancements over previous generations
I purchased a second generation version of this lock in 2017 and it lasted a little over seven years until the mechanics wore out. Not a bad run. Being overall happy with the product, I purchased this latest generation.As the lock has gotten smaller, it is an entirely new installation. However, it is very simple. The exterior of your lock stays exactly the same and will still work with the existing key. Therefore this is a great choice for renters (where the landlord might need access in an emergency) or anyone else who wants to leave their current keys functional.The package comes with a piece of painters tape, which you tape over the outside of your existing lock so that it doesn’t fall out during installation. On the inside, you simple unscrew the existing inside back plate of your lock and store it for move-out, the future, etc.You then place a provided plastic pin on the existing lock pin. Several adapters are provided for the different lock types. My lock has a ‘/’ shaped pin. Then you attach the plate and then “ball” part of the unit which turns the lock and has the batteries. These are attached with two clamps, so that you can remove the “ball” easily at any point.This generation uses two lithium batteries instead of AAs like older models. Having only two batteries makes installation and replacement of them easy. I am now in month three of use with no sign of replacement needed yet. the batteries are CR123A, which look like mini AAs. They are not as ubiquitous as other types but are still available cheaply in bulk such as on this site.This model has two additional features vs. the Gen 2 I had: First, it can connect directly through wi-fi. You don’t need a bridge like Apple Home. This apparently uses a little more battery, but I have it on just in case. I separately still connected it through Apple Home, which is the smart home app I use the most. Setup was very simple.Second, this model comes with a door proximity sensor. This is just a little magnet (or stuck-on) peanut-sized sensor which is placed an inch from the lock and will monitor the door’s ajar status instead of just the position of the lock. You can set an alert in the app where you will be notified if the door has been open from one minute to 30 minutes (your choice via slider).This lock also locks and unlocks slightly quicker and more forcefully than my old Gen 2. Perhaps the lithium batteries give it more juice.Otherwise, the app comes with features like auto-lock, auto-unlock, and a log of all recent opens, closes, unlocks and locks.The only feature in the app which I would like tweaked is the auto-unlock feature, which presently requires you to be a certain amount of distance from your home before functioning upon your return. This is so it doesn’t constantly unlock when you are home. However, the prescribed distance is a little small for me living in a big city. I wish this feature would work even when I’m only a block away not four or five. The suburban equivalent would be it working when you’re at your neighbor’s house down the block instead of driving to the grocery store.Lastly, I think at some point August should make a version of this lock with a rechargeable lithium battery via USB-C. Removable probably so you don’t have to run a long cord.Overall, I think this is a great product though particularly because it’s easy to install and keeps your existing exterior key lock.

Use whichever adaptor that puts the notches at 12/3/6/9 o’clock
If you had asked me yesterday I would have given this lock 2 stars. Been living with it sorta connecting and auto locking or unlocking one time and then not re-syncing the status in the app for almost a year. Tried perfecting the latch so it was smooth and didn’t catch AT ALL for a good while and that wasn’t the issue. We tried getting a better WiFi signal, disabling all the battery draining features/notifications, calibrating the lock, restarting the app etc. Sometimes it would work a couple times and then resume not syncing on the app. The WiFi connection was strong, the log would note the times we unlocked it manually. Still, I was hung up on the lock to app signal being the cause of our issues and got a august connect adaptor to try and help (plus I read that could help slow the battery drain). Turns out even the 4th gen lock doesn’t allow an external connect device so that was a dead end. Maybe the connect I got is an older model or something but I couldn’t get them to link, it just complained there were no compatible devices at setup). Another clue that this wasn’t the cause should have been that even when using the phone’s Bluetooth signal it wouldn’t update the lock status after the first app unlock. Also when we would unlock from the app the light would start turning green on the lock then end with a red once it unlocked.Finally found a FAQ doc that said to make sure the notches on the lock adapter were at the vertical position (12/3/6/9 o’clock) when the lock was at it’s ‘default’ position (unlocked). When I swapped out the adaptor to the blue one from the light brown and recalibrated the lock one more time it started working perfectly. No more weird mismatch between the app and lock position even when the WiFi signal was good! Range of motion is much farther when the lock opens now and it has a fancy chirp to show it unlocked correctly. That chirp made me so happy after fighting with the app this long, but it didn’t compare to clicking the app a second time and having it reliably relock immediately.It felt like it was ‘almost’ working before figuring this issue out so I assumed the app/some buggy firmware was at fault but it was installation error on my part! The rest of the install was so easy. Oh well.Also, go get the rechargeable 123a batteries for this lock. Saw that tip from someone else and just got two sets to swap between. The disposable batteries drain pretty fast and are expensive.

Comprei para substituir um modelo mais antigo. O app não aceita mais configurações de dispositivos fora dos EUA, então para configurar voce tem que usar uma VPN com um servidor nos EUA

I’ve been using August for a long time. Best thing about it is that from the outside looks like a normal lock. My old August failed about 6+ years in. After I did some research I found out August to be the most affordable replacement. I did not hesitate and purchased my 2nd unit.Only to find out that its installation is geo fenced to US and Canada only. Outside, must be trough Yale App, which may NOT support August in all countries.Took a bit of network creativity, but I finally managed to set it up. All good when it ends well,…. just a reminder to those purchasing August from outside of US and Canada that it may not work straight out of the box.

Me gustó todo. Llevo 2.5 meses con él y funciona muy bien. Fácil de instalar y configurar. Me gusta mucho la función de que se abre cuando llego a casa sin hacer nada. Muy ingeniosos. También de que se cierre a los 2 min de que se abrió. Así nunca se queda abierta. También que puedes utilizar automatización como prender algo cuando se abre.Parece que las baterías duran poco. Me empezó a avisar desde hace 14 días de la urgencia de cambiarlas. No he hecho caso y sigue funcionando perfecto. Ya le gané 14 días.

This device will not work outside USA or Canada even though its the international version and sold on the Australian amanzon site. However I did get it working (see bottom of this message)Responce from August:Thank you for reaching out to us!We apologize for the inconvenience this has caused. Let us help!Per ASSA ABLOY’s sale of ‘August and Yale’s US and Canada operations’ to Fortune Brands, ASSA ABLOY has released a new app called the Yale Home app. The new Yale Home app is intended exclusively for locks outside the United States and Canada as they fall outside our August & Yale US/Canada operations.Unfortunately, August products are incompatible with the Yale Home app. Therefore, your lock cannot be set up outside the US or Canada. If you purchased the device from a retailer, contact them about an exchange or a return if possible.We apologize for the inconvenience and thank you for being an August customer.Please let us know if you have any questions or concerns.Have a great day!However I did get it working:Install the TunnelBear app on your smartphone.Configure it to connect to the USAOpen the August app on the same smartphone and set up the lock. It will register now as their system can’t tell you are not in the USA.This is not supported by August though.
