How to Get Properties of Non-Person Users?

We know that filtering states.person by user_id is a common way to get the properties of the user that triggered a given event. However, states.person does not include any user that is not a person as well.
Since my panel tablets login as users that are not persons, how could I get the user info for events sent by them?

I was told on Discord that the templates only expose users that are persons. For real there’s no way to get non-person users too? If so, it seems like a WTH to me.
