Can you show the conditions section? Click on the Actions and the conditions should be shown towards the bottom of the screen. Is there any reference in there to the old device?
For the most part it works, there may be a couple of exceptions or things left to tidy up, but let's politely point those out to help move the product along.
By that I was referring more so to importing a rule definition. I do take your point though, changing / replacing devices is something more people are struggling with as we get to the point in time where people are starting to replace devices more, now that we are 4-5 yrs (?) in to HE's existence, or people are expanding their collection of HE hubs.
Glad to hear you were able to clear up the dependency.
