How to check which user is logged in?

Hi,
How can I check who is logged in home assistant?
I need something like this:

{% if USSER == 'Lemmy' %} 
Yes
{% else %}
No
{% endif %}

It’s not possible. The backend doesn’t have a this concept as there can be 100s of users logged at the same time (even the same user can be logged into multiple devices).

Ah ok, I understand.
Thank you

However, you can check by which user f.e. a light has been turned on…

trigger.to_state.context.user_id

**User: {{ user }}**

Can be used in markdown

I need it, so home assistant to know who of my kids gets there bonus-points.
