Hey Ryan, I had this once a while ago and if I remember correctly it was because I had swapped devices between rooms, and in the Home app, it was showing the same device in two different rooms. Once I untangled that I was able to reset up the device and poof no more log-in nag. See if that might be your issue -- in any event, it's usually somewhere on the user side of the equation as was the case for me.
