August Smart Lock vs Kwikset Smartcode 916 Z-Wave Plus

You can give out personal codes which will unlock the door, and you can have an unlimited number of these codes. However, if you don't have the optional wireless keypad ($79) each user will need to download the app and enter their code there. These codes can be configured to have a time duration where they will expire, or they can be permanent.

This smart lock is installed only on the inside of your door, and doesn't replace your existing lock. This means that you keep your current keys, and installation is a bit easier as you don't have to disassemble your door.

Every time the door locks or unlocks, it will record the data in a logbook. This entry includes who performed the action, and there is space to write a note as well if you wish.

This lock has enough smarts to automatically lock and unlock. Depending on your settings, you can set it to unlock automatically when it detects your phone is near, and automatically lock a few seconds after you leave.

This is one of the few products that works with both Apple's HomeKit and Google's Nest devices. For example, when you unlock your door it can automatically trigger the Nest thermostat to turn on, and the Nest cam to turn off.

The SecureScreen feature requires all users to input two random numbers before entering the actual pincode which makes impossible to guess the pincode by smudges and fingerprints.

If someone does try to break in, the device will sound a fairly loud alarm which should scare away any burglars.

The SmartCode 916 is one of the more subtle and smaller smart locks which should blend in nicely with your interior thanks to the multiple color variations.
