How to: Automate Your Garage Door you have a garage, chances are that at some point, you’ve driven away and wondered, “…Did I remember to close the garage?” 

Since a significant percentage of home break-ins occur through garages, forgetting to close or lock up your door is essentially leaving a welcome mat out for intruders.

Fortunately, a smart home can sense when you’re gone and automatically close up after you. Just as you can lock and unlock doors and turn on lights, electronics, and appliances from anywhere with SmartThings, you can also open and close your garage door with a simple tap of a button. Here’s how:

What you need:
• A SmartThings Hub
• A SmartSense Multi sensor
• A compatible garage door opener (recommended: Evolve relay switch)

After installing the relay switch in your garage and placing a SmartSense Multi on your garage door (which senses if the door is open or close), you’ll be able to trigger your garage door to automatically open/close when you arrive/leave through two different ways:

You can either use your smartphone as a presence sensor and set up a Geo-fence around your home using the free SmartThings app; or you can simply carry a SmartSense Presence sensor in your car/briefcase/keychain/etc to automatically open or close the garage door when you roll into the driveway.

Additionally, you can always manually open and close your garage door simply by tapping a button in the free SmartThings app. Sorry, burglars.

  1. Would it be possible to see additional pictures of how and where you mounted the multi-sensor?

  2. UL has a safety requirement for doing this and unfortunately this method, though effective, doesn’t have the safety aspects required. There are other products from Linear and Telguard that work with SmartThings, but are also safe.

    • Since it simply acts like another button on your opener, the photocell-interference-detector and auto-stop / reversing functions of the door still function. The only safety feature it is missing is a flashing warning light the warns the door is about to close, which I find about as useful as a warning label.

  3. How much SmartThing app? Is expensive?

  4. How can i get this apps?Send more informations .

  5. This is interesting, very useful for sometimes we forgot to close the garage door.

  6. Thank you for sharing


  7. Hi! Want a simple device to open gated entrance? EVAC or emergency vehicle access control is a simple yet convenient device to open the gated entrance of a community. It comes with a coded remote which is available only for emergency personnel. For more information, visit us at

  8. While useful, there’s a limitation to that solution. Most households have multiple cars, and I haven’t yet seen that either SmartThings or IFTT is “easily” able to handle logic statements (IF/AND/OR) such that ‘if sensor A and sensor B aren’t present, close door’. My forays into Github proved unsuccessful, hence the emphasis on “easily”.

  9. Great article I recently discovered this great article about how to choose the garage door
