For both standard and non-standard doors, or doors with decorative door handles, you should consider adding a deadbolt-only smart device to the door to enable remote control and access. A smart deadbolt is simply a locking mechanism that fits into the existing deadbolt cut-out in your door, and connects to the internet to allow for remote access and programming.
The garage door is a common roadblock for home automation, because garage door openers are “dumb”, expensive, and not something you'd want to break. Have no fear! If you pair a SmartThings hub with the Chamberlin MyQ Garage Door Kit, you can control your garage door remotely, and check its current status. You can even automate it using IFTTT and webCoRE.
