Use SmartThings Find with the SmartThings app

Note: You may be prompted to allow location permissions when opening the SmartThings app.

If you’ve lost track of a device, just open the SmartThings app to use SmartThings Find. Your devices will appear on a map so you can easily keep an eye on their locations.

If you ever need to remove the SmartThings Find card from SmartThings, tap the Life tab, then tap More options (the three vertical dots), and then tap Delete. Tap the minus sign next to Find, and then tap Done. You can add it back at any time by selecting it again. Keep in mind that removing the card from the SmartThings app will not uninstall the SmartThings Find feature.

You can narrow down locations and view navigation directions for your misplaced devices using the SmartThings Find card. Or, if you know a device is nearby, you can make it ring loudly so you can find it fast.

You can also select or deselect devices that appear on the map. On the map, tap the Menu icon (it has three dots with three lines), and then tap More options (the three vertical dots). Tap Remove devices. Tap All at the top to choose all of your devices, or select a few by tapping individual devices. Then, tap Remove.

Note: Up to ten devices can be selected at a time.

The Offline finding feature in SmartThings Find can help you locate a missing device, even when it's turned off or not online. Once your device has been offline for 30 minutes, it will produce a signal that can be received by other devices. A nearby Galaxy device user can then assist you with finding your lost device by sending that information to Samsung’s server. On the other hand, the feature also allows you to encrypt your device's offline location so only you can access it. 

However, you'll first need to turn on the Offline finding feature in order for the service or offline encryption to work.

Note: You can also turn on the Offline finding feature through your phone's or tablet's regular settings. Navigate to and open Settings, and then tap Security and privacy. Tap Find My Mobile, then tap Offline finding, and then tap the switch at the top to turn it on.
