Reset the Welcome Code on your SmartThings Hub
If you're having any trouble with the initial setup on your SmartThings Hub, you may need to reset the Welcome Code. The SmartThings Hub v2 (2015) and the SmartThings Hub v1 (2013) are each given a unique 6-character Welcome Code that is required to activate them. However, keep in mind the SmartThings Hub v3 (2018) and SmartThings Wifi do not use Welcome Codes.
Warning: All device connections and configurations associated with the Hub will be lost when you perform a factory reset. All devices connected to the Hub must be reset or excluded before they can be reconnected.
When to reset
You may need to reset your Welcome Code if you see one of the following messages during setup:
No unclaimed Hub found for that Welcome Code
Invalid Welcome Code
Zigbee ID must be unique
This Hub was previously used and cannot be activated
Hub v1 (2013)
If you have a Hub v1 (2013) or a Hub v2 with firmware version below 17.11, you can try to reset the Hub and Welcome Code by deleting the Location it's assigned to.
If you do not have the account access needed to delete the Hub, contact 1-800-SAMSUNG (726-7864) and provide the Hub's serial number. You may also need to provide a photo of the Hub's serial number and barcode, located either on the bottom of the Hub or inside the battery compartment.
Hub v2 (2015)
A factory reset is the only way to reset the Welcome Code on your SmartThings Hub v2. After the reset, you can reactivate the hub using the original, unique Welcome Code that was included with your Hub. It should be located either on a card under the Hub's tray in the box or inside the Hub's battery compartment.
First, make sure the Hub is plugged in with the included power and network cables. Then, use a small tool to press the RESET button on the back of the hub, releasing it when the LED on the front switches from flashing yellow to solid. If you do not release the button, the hub may not reset. Once the LED on the Hub turns solid green, try completing the setup.
If resetting the Hub does not resolve the issue with the Welcome Code, contact 1-800-SAMSUNG (726-7864) and provide the Hub's serial number.
Note: The firmware version needs to be 17.11 or above.
