WWN Losing Room Assignments

[gniknalu]

Using WWN for 3 Nest Smoke/CO2 sensors.  WWN creates 3 CO2, 3 Smoke sensors and 1 "Vera Connect WWN" devices.

I will assign them each to a room. One by one - wait for their assignment to move, then do the next until they're all assigned.

A few days later, they're all back to the "No Room" group. Has anyone else experienced this?

Fast Forward 10 hours and they're all back to their appropriate rooms. 

I don't know what is going on here . . . .
