Persons are now threated the same as device trackers, so the logbook states
"<name> is at <location>" or "<name> is away" instead of "<name> changed to <location|not_home>"
Binary sensors now show phrases that relate to their device_class attribute.
So "Front door is closed" instead of "Front door turned off" or "Hallway PIR detected movement"
instead of "Hallway PIR turned on"
