Si I have had issues where none of my state historys graph, or logbook will load.
I have tried deleting the homeassistantV2.db and log file, then restarted. but still none.
I have even done a full wipe and restore from snapshots but still no history graph.
the only clue I got(maybe), is in the log under developer, I have a huge list of:-
‘WARNING (MainThread) [homeassistant.components.device_tracker] Updating device list from legacy took longer than the scheduled scan interval 0:00:12’
I have even tried all the above after comment out the device tracker in config file, any help would really be appreciated.
thanks.
