Amazon has discounted the August Smart Lock (Second Generation) to just $124. That is down over $100 from its original price of $229. Making this a pretty fantastic price point to pick up a smart lock for your home. This price likely won't last forever, so you'll need to grab it as soon as possible.
The August Smart Lock (Second Generation) is not the latest version, as there is a third generation available now. But the differences are pretty minimal. This one does have support for Amazon Alexa. Allowing you to ask Alexa to unlock or lock your front door, and even ask Alexa for the status of your door. The August Smart Lock is a great lock to pick up, since it does use your existing lock and keys, and really just adds some WiFi and Bluetooth to it. With the August Smart Lock, you'll be able to give out a digital key to your kids, or if someone is watching your home while you're away. You can also take away the keys pretty easily, which is great for having a house sitter. The lock is also able to auto lock and unlock, so you can set it to unlock when you get within 200 meters of your home, which is especially handy when you are coming in with a handful of groceries.
