SmartThings device does not respond or the status is disconnected or incorrect

If your ZigBee device is not working with your hub, be sure to check the power to the device and the hub's network connection. However, it may be necessary to reset the ZigBee device and restart the hub to fix the problem.

If you have multiple smart devices of the same type, changing the name can come in handy.

The SmartThings app uses your Samsung account credentials. To create an account, you simply need to sign in with your Samsung account. To log out, you will need to remove the account from the app.

SmartThings has two types of notifications: traditional notifications that appear in your Notification panel and activity notifications that appear in the SmartThings app. You can manage both types of notifications depending on what you'd like to see.
