I accidentally deleted the Hubv2 from my Smartthings network using the Smartthings app. Meant to do a device, but did the hub. I noticed you can’t get this information back, but I also can’t re-add the hub back to my account since it asks for a Welcome Code that I no longer have.
What is the process to get a new Welcome Code so I can rebuild my network?

she is going to ask you for the Serial # located on the label on the bottom of the hub

Hi @bmurphy765
Could you please double-check the serial number you shared?
We weren’t able to find any records associated with that number in our system.
Nevermind. I called the 800 number and got help. Thanks anyway
