About Lovelace Plugins

The dowload and install of plugins is very basic. This is not HACS.

LOVELACE_PLUGINS should be a space separated list of author/repo pairs, e.g. "thomasloven/lovelace-card-mod kalkih/mini-media-player"

LOVELACE_LOCAL_FILES is for the currently worked on plugins and should be a list of file names which are mounted in /config/www/workspace.
