I had to create the www folder in the config directory. Then I put the images in this folder.
The url to this folder is http://home_assistant_url:8123/local/image.jpg
I just used the entity_picture: /local/image.pgn path in my customize.yaml file for the entity and it read the picture I added in the directory under /home/homeassistant/.homeassistant/www/image.pgn. (After creating the www directory and adding the picture of course.)
If you use the customize.yaml don’t forget to add customize: !include customize.yaml in configuration.yaml under homeassistant:.
Is this the case in 0.84.6?
I just created the www folder in my config folder, and uploaded a image.png file, and i’m unable to access the file from http://:8123/local/image.png
