Tracking devices

Why i always get “no state history found” about my two tracking phones? They are correctly recognized at home or not at home, but how to have an history of how much time a device is at home or not at home?
Must i set some particular config?

With my system it takes a while until the history shows up, might be the same with yours.
But you should be able to look it up under the history menu item or use the History Stats component for that:
