How do I unnasign a device
You have to forget it and then when it re-appears you can leave it alone.
Hi @BLUE242, we just introduced some changes to profiles in xFi that now allow you to unassign a device. To unassign a device from a profile, select the Profile from People, and scroll down to the assigned devices section. Click on "Unassign" and then click the trash can icon next to the device you wish to unassign. Once done, click Finished.
You can find more on this in the Managing Profiles with xFi article.
