I monitor 3 homes, each with version 38.10. One hub shows most devices offline, but only in the IDE. The app shows they are okay but custom apps show they are offline. The other thing is that all the offline devices are local DTH’s. But there are some local devices ONLINE as well. So it’s confusing where the problem may be, or if there is a problem at all. Maybe I should wait until after the weekend when the regular ST crew will sort it out on Monday?
Update: Some cloud based devices went OFFLINE now as well. I also reset power on the hub without change.
