To anyone experiencing this issue I appear to have found one of the causes for the “Could not update the setting. Please check your connection” error. It seems certain entities in home assistant will cause this error to appear even if there isn’t a connection problem. To eliminate this being a cause set expose by default to false then specify individual entities to expose. Examples below:
google_assistant:
project_id: !secret project_id
client_id: !secret assistant_id
access_token: !secret assistant_token
expose_by_default: false
.
customize:
light.light_name:
google_assistant: true
google_assistant_name: light one
