The August Smart Lock was easy to install. It works well with Siri HomeKit and Alexa. I find the Apple Watch app finicky as to when it wants to work. I have been able to lock and unlock successfully using Siri through the Apple Watch. I especially like the auto lock feature. The only advice I can give is if you have to remove the device from your door for any reason, make sure you remove a couple of the batteries to power it down before you reattach to your lock. If you don’t, it will tell you the lock is jammed. I discovered that when I had to get my door refinished.

Although skeptical, after several weeks, I find the AUGUST smart lock to be just what we needed. Note that there may be occasions when your door does not line up properly with the dead bolt. This will take time to adjust; (weather conditions also attribute to the door 'sticking'. Note it is NOT the unit. once you have identified the correct sleeve which adjusts to your existing unit, you are on your way. the app works great. BE MINDFUL that if you do not have your phone with you and decide to go out of the door, well, you may be looking for another way back inside if you have the auto lock on feature on. Overall, very pleased with this unit. Works well with Alexa. Did not use the screws to mount the sensor. If you use only the adhesive sticker that comes with the unit, it should be sufficient if you are concerned with putting holes into the door frame. Nice feature is that from the outside the existing hardware remains the same so you are able to maintain the original key lock.

Setup was remarkably easy, made more challenging by myself not measuring anything. I should’ve looked at the size of the lock to ensure it would fit, instead I ended up having to Dremel out some metal siding on the door to get the unit flush and allow the wings to close. Entirely on me and not necessarily a fault of the device.

I bought this model because it is Apple HomeKit compatible. It was really easy to install. I have a new Schlage deadbolt but there were other options which looked easy too. Set up through the August app on my phone was quick and dare I say it again, easy. It works as advertised. So far I just use it to Auto Unlock as I approach the door. I didn’t need that before but very handy in a condo. It’s cool unlocking for other people too when needed.

I have purchased two, one for my sister and one for my self. I took a little longer time before I write this review, because I can discover more issues. So far the August smart lock gave me no issues and it's a great product. Before I install anything, I always go on YouTube to search and watch DIY of installation on any of products. I have installed August Smart Lock Pro+ for about a month now and the only issue I have is one error message. To warn me the lock has an locking issues, I make the deadbolt lock plate adjustment on the door frame and it works perfectly now. I took a little time to install the magnetic sensor inside the deadbolt lock insert plate by the door frame. I want to make a better look instead drill two screws holes and a sensor sticking outside the door frame. Please see the two pictures I attached. The only downside is if you decide to use the auto function to lock your door, please make sure you either have a key or your phone with you. Otherwise you will be lock outside of your home while door is closed. I found out if you want to open the door for someone else while away from your home, you will have to refresh the app before you can do so. That I don't like, otherwise it's a great product.
