This is one of our favorite smart locks. We gave it a score of 80 in our review. It's easy to install and the smart lock won't take up too much space, so it shouldn't look too clunky on your door — it's slimmer than prior iterations. You won't need a separate bridge device to use the Wi-Fi feature either, as it can directly connect to your network. On that note, August's fourth-gen smart lock is only compatible with 2.4GHz networks, so you may need to adjust your router settings to account for that.

The smart lock should work with most existing deadbolts, so you'll be able to use the same physical keys if need be. That's handy for when your Wi-Fi is on the fritz. Otherwise, you'll be able to lock and unlock your door remotely, including with the likes of Alexa and Google Assistant. You'll also have the ability to provide guests (such as kind friends who are checking on pets and plants while you're away) with timed-entry keys, which will allow them to enter without having to wait for you to unlock the door manually.
