You’re welcome, @nickh66.
Here is a more complete example using the state_changed event. Replace light.smart_bulb_3 with some light entity you have.
- alias: "Test"
initial_state: true
trigger:
- platform: event
event_type: "state_changed"
event_data:
entity_id: light.smart_bulb_3
action:
- service: persistent_notification.create
data:
title: Test
message: >-
{% set user_id = trigger.event.context.user_id %}
{% set triggered_by = (states.person | selectattr('attributes.user_id','==', user_id)) | list | first or "nobody" %}
{% set first_name = "System" if triggered_by == "system" else state_attr(triggered_by.entity_id, "friendly_name").split()[0] %}
{{ first_name }} switched {{ trigger.event.data.new_state.state }} {{ trigger.event.data.entity_id }}.
