Hi,
I guess this is suited for a beginner like me 
I found a few blueprints that would work with a schedule which may be handy for some, but as the sun is changing these value would need constant adjustment wheras I was looking for an automation.
Moreover, other blueprints were often grown over time and so it was impossible for me to amend it to my needs as these were too complex for my know how. So, this one is very basic with descriptions and alias inside, so even months later I will understand, when looking at it.
It reduces brightness before turning off. A signal for you in case you want to keep the light on, but the sensor doesn’t know you are still in the room.
I guess I have this for tile on my dashboard, not for the automation.
Go to your file configuration.yaml and add this:
# User area
template:
- sensor:
- name: "Sun - rise time"
state: "{{ as_timestamp(state_attr('sun.sun', 'next_rising')) | timestamp_custom('%-I:%M', true ) }}"
Continuation of the blueprint
Motion-Light-Sun-Brightness (HA-m-l-s_b-00.yaml)

Some of my notes that helped me to use the editor within Home Assistant to build a draft.
Input
link
These are the input fields that your blueprint can provide.
The input_select integration allows the user to define a list of values that can be selected via the frontend and can be used within conditions of an automation. When a user selects a new item, a state transition event is generated. This state event can be used in an automation trigger.
Target
empty
Mode
empty
Trigger
The trigger(s) which will start the automation. Multiple triggers can be added and the automation will start when any of these triggers trigger.
Conditions
For example, a condition can test if a switch is currently turned on or off.
Unlike a trigger, which is always or, conditions are and by default - all conditions have to be true.
All conditions support an optional alias.
Action
The sequence of actions to be performed in the script.
brightness_pct = Percent
Template condition
The template condition tests if the given template renders a value equal to true. This is achieved by having the template result in a true boolean expression or by having the template render True.
Sequence (auch Teil eines Skripts)
Scripts are a sequence of actions that Home Assistant will execute. In scripts, an action is called sequence.
