There are still some neat integrations available with Bluetooth-only hotel smart door locks, though. For instance, the August lock has an opt-in auto-unlock feature that's tied to your phone's Bluetooth. Lock your front door, leave home, then return within Bluetooth range, and your front deadbolt will automatically unlock.

If you want to control your lock remotely, adding passcodes or letting people in while you're away, you're going to need a Z-Wave hub or Wi-Fi-connected smart lock.

Z-Wave

Examples: Poly-Control's Danalock (Z-Wave version), Schlage Camelot Touchscreen Deadbolt, Yale Real Living Touchscreen Z-Wave Deadbolt

Z-Wave smart locks are available from brands like Schlage, Poly-Control and others. Unlike Bluetooth locks, Z-Wave locks don't connect directly with your phone. Instead, they'll need to connect to a Z-Wave-compatible hub. That hub will translate the lock's Z-Wave signal into something your router can understand — once it does, you'll be able to connect with your lock from anywhere.

Samsung's SmartThings and the Wink Hub are two examples of Z-Wave control hubs. SmartThings in particular works with a bunch of third-party Z-Wave locks, from Kwikset and Poly-Control to Schlage and Yale. (Here are the complete lists of SmartThings- and Wink-compatible locks.)
