Just found out that my cloud file in /.storage/ contained huge amounts of no-more-existing entries. I updated them manually, to only hold existing ones, but decided to do an experiment: simply take out the file completely, and check if it would rebuild, and, how.
to my amazement, it did rebuild, but it contains not a single entity, and is working just nicely, with this content only:
Since I do have all included entities listed like this:
# https://www.nabucasa.com/config/google_assistant/
cloud:
google_actions:
filter:
include_entities:
xxx.xxx
I was wondering how this is working at all, and why it (the hidden file) isnt updated at all.
