Installing the August Smart Lock Pro over your existing deadbolt is pretty simple, and today it's a bit more affordable as well. For one day only, Woot is offering the smart lock in dark grey for $169.99, so you can start controlling your door's lock using your phone or even with your voice. Today's deal saves you a full $60 off its regular price at Amazon, and using your Amazon Prime membership will earn you free shipping during checkout too. Otherwise, everything at Woot ships for $6 per order.

The August Smart Lock Pro lets you begin locking and unlocking your door using your smartphone, and it's much simpler than needing to go into an app and press 'Lock'. This device automatically locks the door behind you when you leave and unlocks it when you come back home by utilizing Bluetooth Energy technology encryption. There's also an app which allows you to grant access to whoever you choose for a specified amount of time, whether that be a few hours or a few months. The app will also let you know whether your door is securely closed and locked or not with August's Door Sense.

This smart lock is also compatible with voice assistants like Amazon Alexa, Siri, and Google Assistant for voice control, though you'll need a compatible device and the August Connect Bridge to enable that functionality.

If you were lucky enough to grab the refurbished Ring Video Doorbell on sale for $54 this week, this would be the perfect complement to that purchase. Those who missed it can still save and snag one for $59.99 right now.
