If you have used Home Assistant it is very likely that you also glanced at the "History"-function of the GUI. I really like this view, because it shows you relevant data in a simple way and it is very easy to find basic connections between elements. So I would like to use this feature also in the future. So you might ask yourself "Where is the problem?". If we have a look at the documentation of Home Assistant you will notice that the default database is a sqlite3-database.
