Same Google account means same protectors. Exact cache names vary by Home app builds. Keep units online during moves. If history thins, check the home structure first. A second home with a similar name is the classic split cause. Monthly tests log to the same timeline automatically. Check the in app storage readout when sizes look wrong on different releases.
