It seems that your configuration.yaml doesn’t properly include customize.yaml
Changes made here won’t affect your configuration.
this message was in customize in HAssio.
it used to work for me, something went wrong with the last hassio updates.
I have customize configured just like before.
I tried customize: in config file manually then tired from hassio what should i do.
my overview is fulll and i can’t hide the entities
Originally I have the customize entered manually in the config file and was working before the update, or what ever I did!! Next I tried using cutomize in a different file and calling it from the config.
Original like this:
customize:
if you put customize:` anywhere in the config file it has to be under Homeassistant:`
and make sure to be 2 indent and to add some kind of custom entity under that customize:
if you put customize: somewhere else in the config file and had 4 indent HA will compile with no error but when you reboot HA all the cutomize entity will not apply.
