Problem: want to add the Smartthings Hub 2018, but cant add it in the app and not all the categories are showing.
Extra Information: I live in The Netherlands, but set an router VPN up that is connected to New York. And also using location spooving on my phone and the VPN ofc. (new smartthings/samsung account created while in “New York VPN”)
Thank you from Mika Leinders 
It sounds like you’ve done everything expected, but when you go to account.samsung.com what does your country/region say? It should look like this:
Cant find it, but the writing is in dutch so i guess something isnt how it should be
Look under your profile:
Even though it’s in Dutch, hopefully Profile is still the first option?
Ahhh, thnx yeaa… the country is in the Netherlands as well, there is no option to change it. New account, and create the email via the VPN aswell? Or should i just contact Smartthings that i want the change the country?
This has been noted in other Hub V3 threads but bears repeating: the US Hub V3 is designed specifically for the US market and complies to US radio regulations. Running a US Hub V3 in other countries is likely to be illegal. Running a hub in a country it was not designed for may cause radio issues for you and others near you.
You can’t call SmartThings to change that, only a call to Samsung will work. You’ll have to provide a valid address and other criteria, and then you’ll receive an email with an electronic form to process. Once that gets approved and validated, your region/country will change.
I know because mine was wrong and I needed to get it changed since I live in the Eastern part of the U.S. and the new SamrtThings app would not load SmartApps for me.
Hy Mika, how you’ve solve it? i have the same problem. I’m in Argentina, and cant add my smartthing hub v3 with de app.
