Person entity: how to use "user_id"

It’s a unique ID assigned to the user that, for example, comes in the context for an event indicating which user triggered the event. You can also translate it into a username with a template like this: {{ states.person|selectattr("attributes.user_id", "==", "mylonguserid")|map(attribute="attributes.friendly_name")|first }}

I don’t think it’s possible directly with SQL.
