Transfer from Template Playground to template.yaml

Configuration
1

The following code works in ‘Developer Tools|Template’-Playground:

{% set ns = namespace() %}
{% set ns.morning_prices = {} %}
{% set ns.mean = 0 %}
{% set ns.total_counter = 0 %}

{% for i in range ( 0,  int(states('sensor.hour_of_sunrise')) ) %}
  {% set ns.mean = ns.mean + ((states.sensor.current_spot_electricity_hour_order.attributes.values()|list)[i]).1 | float %}
  {% set ns.total_counter = ns.total_counter + 1 %}
  {% set ns.morning_prices = dict(ns.morning_prices, **{(states.sensor.current_spot_electricity_hour_order.attributes|list)[i]:(states.sensor.current_spot_electricity_hour_order.attributes.values()|list)[i]}) %}
{% endfor %}
{% set ns.mean = ns.mean / ns.total_counter %}
ns.morning_prices {{ ns.morning_prices }}
ns.mean {{ ns.mean }}

and does show the result as of:

ns.morning_prices {'2024-11-27T00:00:00+01:00': [6, 3.213], '2024-11-27T01:00:00+01:00': [5, 3.033], '2024-11-27T02:00:00+01:00': [2, 2.818], '2024-11-27T03:00:00+01:00': [3, 2.866], '2024-11-27T04:00:00+01:00': [4, 2.98], '2024-11-27T05:00:00+01:00': [7, 3.519], '2024-11-27T06:00:00+01:00': [10, 3.906], '2024-11-27T07:00:00+01:00': [22, 4.471]}
ns.mean 3.35075

transferring this into template.yaml

  sensor:
    - name: morning_prices
      state: >
        {% set ns = namespace() %}
        {% set ns.morning_prices = {} %}
        {% set ns.mean = 0 %}
        {% set ns.total_counter = 0 %}
        {% for i in range ( 0, int(states('sensor.hour_of_sunrise')) ) %}
          {% set ns.mean = ns.mean + ((states.sensor.current_spot_electricity_hour_order.attributes.values()|list)[i]).1 | float %}
          {% set ns.total_counter = ns.total_counter + 1 %}
          {% set ns.morning_prices = dict(ns.morning_prices, **{(states.sensor.current_spot_electricity_hour_order.attributes|list)[i]:(states.sensor.current_spot_electricity_hour_order.attributes.values()|list)[i]}) %}
        {% endfor %}
        {% set ns.mean = ns.mean / ns.total_counter %}
        {{ ns.total_counter }}
      unit_of_measurement: "Kcs"
      attributes:
        morning_prices: "{{ ns.morning_prices }}"

will result in ‘unavailable’ state

This code should deliver a dict of energyprices between 0 and 8 o’clock (actual status of hour_of_sunrise) and the mean price.

The scope of a jinja template is limited to the key in which it is placed.
You can’t access ns.morning_prices in the attributes part anymore, you need to repeat the entire template.

BTW, you can combine these firs 4 lines into one

        {% set ns = namespace(morning_prices = {}, mean = 0, total_counter = 0) %}
