Hi
I have this warning in my log file.
17-04-17 11:41:53 WARNING (MainThread) [homeassistant.helpers.entity] Update for media_player.stue is already in progress
17-04-17 11:41:53 WARNING (MainThread) [homeassistant.helpers.entity] Update for media_player.kkken is already in Progress

Anyone knows what it Means and what to do? It is referring to my Sonos but they Work fine.
