I have a smartbar that has several times lost it's address information. Once I go up and address it, it is fine for quite some time then it will eventually loose it. The smartbar directly beside it has no issue, just the one. At first I thought it was coupled to power loss. It always seemed to happen after when there was a potental loss and when noone was in the building.
Recently it has done it so I am told either right before an event with no real cause.
What could be causing one to loose address and not the other?
What should I do to fix this issue (troublesome to keep addressing it)?
