    • Comparison of August, Schlage, and Lockey
Color: Silver Style: WiFi Smart Lock
Update after 4 months: I still really like this lock. Easy installation. Excellent app. Doesn't require re-keying (since it uses this existing deadbolt). Doesn't require a hub. But one problem has come up, and it's significant. As far as I can tell, there's no way to check the battery level in the app. The first warning you get is an email message saying the battery is critically low. Unfortunately, in our case, that email message arrived three days after we closed up the house and left for another state to take care of an elderly parent for an indefinite period. The whole point of putting this smart lock on the door was so I could let people (e.g., the furnace repair guy) into the house while we were gone. Now I can't do that, because the batteries are dead, which defeats the whole purpose of the lock. The lock should have a battery status indicator, like a phone, so you can decide whether you need to preemptively change the batteries if you'll be away for awhile. The batteries this lock uses are expensive, so I don't want to throw away good batteries, but I also don't want them to die unexpectedly. Why doesn't the app have a simple battery monitor? Taking off a star and hoping they fix this. [Update to the update: I've now been using the lock for 8 months, so I'm getting a good sense of battery life. The lock doesn't have a battery meter, but it does send a message that the batteries are "critically low" when they need to be replaced. The first set of batteries lasted 3 months. The second set lasted 3 months. So, if you're using this lock in a situation where you can change the batteries every 3 months, it's a good choice. as noted before, the lock offers many advantages over other smart locks. But if you need a smart lock for a location where you can't change the batteries every 3 months, a lock with better battery life would be a better choice. That might mean a smart lock that uses a hub rather than direct wifi, since a Bluetooth/Zwave/Zigbee connection probably uses less power than a wifi chip.] This is my third "smart" deadbolt lock. With each purchase I've relied on expert reviews, which have been valuable, but technical reviews can't capture the experience of actually living with a lock, which is what I'll try to capture here. Here are the pros and cons after living with several different locks. Schlage Connect BE469. My first experience with the Schlage smart lock was good. It was relatively easy to install, and it had a removable ring, making it one of the few smart locks that fit in smaller bore holes (which are surprisingly common in any house old enough to vote). The Schlage has a keypad, so you can get in even if you don't have your keys or your phone. It also has a traditional key, which is useful if the batteries die, although you'll have to have a locksmith re-key it if you want the key to match others (e.g., your back door). The biggest disadvantage of the Schlage lock is that it requires a hub for remote control, like letting a contractor into the house while you're at work. The first Schlage BE469 I installed worked fine with my Wink Hub 2, but then Wink had financial troubles and started charging a monthly fee. So I switched to a Samsung SmartThings Hub. Weird thing is that the hub worked fine to control one Schlage, but said the other Schlage (which was bought two weeks later on Amazon) was too old a version and wouldn't allow advanced features like remote control. I spent months trying to solve the problem (upgrading firmware of both lock and hub, uninstalling and reinstalling, deleting and reinstalling the app, etc.), but nothing ever worked. I finally removed the second Schlage and replaced it with this August lock. So ... on to the August lock. First of all, installation was a breeze, since the lock using the exiting outside keyed portion and deadbolt, replacing only the inside thumb latch. Easy. Second, the app is very well designed, including the guided tutorial for both physical installation and smart setup. After setup, the app is super intuitive, and the graphics that indicate door status are smart. The log file is complete, accurate, and easy to read. Third, since August replaces only the lever, you can keep your existing key as backup. Fourth, the new August lock is a lot smaller than earlier versions. Downsides: No external keypad, so you have to have either your key or your phone for access. This is a bummer, since I often take neither for walks. Also, rated battery life is shorter than for other locks -- this is the price of direct WiFi. The lock comes only in silvery grey -- I wish there were a brass option to match my other existing door hardware. The biggest factor for me, and why I really like this lock, is that the remote feature works reliably. That's a huge deal for me, since the primary reason I got the lock is so that I can let in contractors when I'm not home. I can open the lock then relock it when they leave, without giving them a keypad code. The remote locking works reliably even though my deadbolt isn't perfectly aligned (we normally have to push the door shut before throwing the deadbolt, but the August lock gives it a second then third effort and always manages to get the bolt in place, even without holding the door shut). Last, but not least, I also have old-fashioned mechanical keyless locks on other doors. It has push button buttons and you set the combination mechanically inside the lock before installing. No batteries. The brand I have is a Lockey. The downsides are that you can't open the lock remotely with an app, and if you have to give out the combination, then the person you gave it to will have access unless you physically remove the lock and change the combination. The upside is that you don't have to carry a key or a phone. Another upside is that this type of lock is incredibly hassle and maintenance free -- I installed Lockey mechanical locks on an exterior garage door and two basement doors 25 years ago, and they're all still working great. If you don't need to lock and unlock your door remotely, this old mechanical technology is worth considering. That's it. I hope this real-life experience of living with different generations, technologies, and brands of smart locks over the past quarter century is of some use to you in deciding which lock will best serve your needs. ... show more

    • Awesome lock for HomeKit.....IF you know all the details....
Color: Silver Style: WiFi Smart Lock
I normally don't write a review as fast as this (I got my lock and installed it yesterday), but there are some important facts that I didn't realize when I bought it. This is for all my HomeKit people, I am a 100% pure Siri operated house. My requirement is that everything I buy and install must be HomeKit compatible. I don't want to deal with multiple electronic personalities in my home, it is already crazy enough as it is. I came across this lock initially because Amazon listed the older gen version on sale for under $100 (Used-Like New). I started researching to see the differences between that one and this one. The old one required a plug-in bridge in order for the lock to gain WiFi Access, whereas this one has WiFi built in. And this one is sleeker, newer, better, etc..... I am one of those who operates on the policy that if it costs more, its better, so I buy it (no judgement please). Anyway, here is the little nugget that is hidden away in the August help articles. Well, maybe it isn't that hidden, but I certainly didn't realize it. If you are using HomeKit, then the lock MUST be within BLE (Bluetooth Low Energy) range of your home hub. For me, I use Apple TV 4K as my hub. Which is in my living room. Which is about 80' or so away from the detached garage where I installed this lock. But fret not, there is a very simple work-around (which I'll get to in a minute). Install of the lock, mechanically at least, was super easy. Connecting to WiFi and getting the app set up was a bit of a pain. Now, to be fair, I use a Netgear Orbi mesh system, and my satellites were in need of an update, so its possible that played a role. But I had to reset the lock twice before I could get the thing reliably online. First few attempts, wouldn't connect. Then, it connected, but wouldn't give me a signal. Finally, I got it all squared away and the lock was good to go. Or so I thought. Then came the HomeKit part. So, you have to setup HomeKit through the August App. But, at the time, I wasn't tracking the BLE range for it to work. So I kept having problems. I ended up deleting the lock from my home through the Home app. But, when I did, even though it was gone, the lock was still registered, so I couldn't re-add it. I did some internet searching, found a help article that had the answer. I actually had to remove the lock portion (not hard, two little black clips that open out), then hold a red button on the back of the unit for 7 seconds to reset the lock. After that, I was able to get it back into Apple Home. But I still spent the next 30 minutes trying to figure out the "No Response" problem in Home. Which led me to the inter-webs, which led me to the help articles, which eventually led to the knowledge that, despite the fact that it is a WiFi enabled app.....it uses BLE for HomeKit. Seems dumb, but is what it is. Now the workaround, when you have a device setup as a hub for Home (iPad, TV, Homepod), it acts as a BLE hub as well (if you are home smart-er than me, don't judge my terminology, I'm new here and learning as a go). Anyways, when you add hub devices, they automatically act as BLE extenders. So, for example, in my home, I've got an Apple TV in the living room, which is my main hub. I then have a few HomePod Minis through the house for Siri control and ease of access. The HomePod Minis passively act as BLE range extenders (Apple never ceases to amaze). The WiFi lock on the shop no-worky, but when I move one of the HomePod Minis out to the detached garage, it acts as the BLE extender, and bam, lock works. All in all, I love that this lock only replaces the back thumb plate, that it is very discreet and no indication of a smart lock from the outdoors. It is sleek looking, makes cool robot noises, and very smooth in operation. Armed with the knowledge I have now about HomeKit operation, I can comfortably move forward with swapping the rest of the locks on my property. But, to be fair, this is a day one review. I may be back after a month of operations with some more accurate feedback. But hopefully, you the reader can be saved the time and effort it took for me to get to this point, and just skip straight to the "yay, it works!" part. ... show more

Review Image by Surfin Waffels Surfin Waffels
-Uses 2x 123A batteries a week. You should consider rechargeable batteries as this device is power hungry. Wish they made a wired model. -has a hard time connecting, sometimes it takes 10-15 minutes to figure its life out. This tends to be related to battery life. Wish they made a wired model. - Grate for peace of mind, love being able to check to see if i locked my door, which is most of what i use this product for peace of mind. Using the lock and unlock feature consumed all the power in the batteries making it confused at times. -Sometimes it forgets what it is and wants to be re-oriented. Not a huge problem but super inconvenient when you are in a hurry. -For a 4th generation product i would have expected a little more awesomeness. If you are willing to work with it its not so bad. -to whom ever created this product, find a 10000 mAh battery pack with usb c charging. i feel like this would help your device cope with life. There very small now you need it. ... show more
