I have one Samsung account, but 2 hubs in different locations. I have IFTTT service on one hub, but not the other. How do I add the service to the other hub?
AFAIK, you can’t, at least at present. Not sure how this will work out after IFTTT is redone for the Groovy deprecation. This has been a long standing issue. @JDRoberts spoke on this some time ago. He may have further information.
At one point you could do this with two different IFTTT accounts, I don’t know if that’s still true.
And as @Bry mentioned, we have been told the IFTTT integration will be rewritten for the new architecture, so there’s no telling how it will work then.
