Getting to Know: The SmartSense Multi

It’s important to get to know your SmartThings because, y’know, they’re going to be living with you. We recently sat down with the SmartSense Multi to hear what it had to say about how it can make your home smarter, safer, and better in its own words.

Tell us about yourself:

“I’m the most versatile and dynamic member of the SmartThings family. I act as a movement, vibration, orientation, and temperature sensor all in one. I’m a quadruple threat. I can do it all. If each device in the SmartThings family were part of a boy band, I’d go on to have the most successful solo career.”

What makes you smart?

“I can detect whether an object like a door or drawer is open or closed, sense when valuable or off-limits items have been moved or tampered with, give temperature readings, and feel vibration. I also have a built-in orientation reader, so I can tell when your garage door is open or closed.


But there’s more! Put me on a mailbox and I’ll tell you when the postman arrives, place me on top of the dryer and I’ll let you know when your laundry’s done, or keep me inside a cookie jar and I’ll let you know if your kids (or four-foot tall cat with opposable thumbs) is trying to sneak dessert before dinner.”

How do you work with the other SmartThings?

“In addition to offering lots of convenient solutions, I’m also a great security tool–both in and out of the house. I’m teeny-tiny, but can deter a burglar. You see, if a door or window unexpectedly opens or is jostled, I’ll alert you immediately. Moreover, if you have a siren hooked up to your SmartThings, I’ll tell it to sound ASAP. If a kid or guest tries to access dangerous or valuable items (chemical cabinet, jewelry case, gun cabinet, vintage Nintendo Power Glove, whatever…), I’ll let you know.”

Tips: Adding a new SmartSense Multi to your SmartThings Hub can be done in two simple steps:

    1. On the “My SmartThings” screen, scroll to the bottom of your device list, and hit the “(+)” icon.
    2. Remove the battery blocker from your SmartSense Multi.

A few hints when placing the Multi:

  1. Look closely in your SmartThings box: There is adhesive tape in there to help you mount the Multi.
  2. Be sure to clean the surface of the door, cabinet, or drawer before you place the Multi. When placing, hold it in place for rsz_photoabout 20 seconds to make sure it’s secure.
  3. When holding the magnet (the smaller of the two pieces) the side with the two small holes in it (pictured here on the right –>) should connect to the sensor and not stick out.
  4. In the video below, Alex has the sensor on the door frame and the magnet on the door. You can place your Multi in the opposite way, too: magnet on the door frame and sensor on the door. Play around, feel it out, and whatever works for you and registers in the app, go for it.

  1. I sure would like to see an app that notifies me when the washer or dryer is done. This application has been mentioned in several areas on the website, this is why I got the Multi device because I have an old-fashioned washer without an alert sound. Can’t find the app to do what you advertise in the apps available for download.

  2. We like to leave our windows open when the weather is nice. Can the multi be set to set off an alarm if a window is opened further or would this require multiple magnets per window (one for the closed position and one for an open position)? And if it does require more magnets can they be bought separately?

    • Hi there. I am interpreting your question to be around detecting intrusion while your windows are partially open. While I think this could be made to work with multiple magnets it would be difficult. You could easily set it up to be notified when the window moves however, when it is in either a closed or open state (and probably also modify it to only be in one state). There is a vibration sensor in there as well.
