Car charging

[overas]

I want to charge my car from 22:00 to 06:00 with lowest price. I have already made a binary_sensor template using the attributt "is_five_cheapest" and used the binary_sensor in the condition. How can I make a template with only the cheapest prices between 22:00 to 06:00 using Priceanalyzer?
I want also to thank you for your work with Priceanalyzer.

      - name: "Pricenanalyzer five cheapest today"
        state: >
          {%set current_hour = state_attr('sensor.priceanalyzer_kr_sand', 'current_hour') %}
          {{current_hour.is_five_cheapest}}

alias: "Easee: Lade bil"
description: ""
trigger:
  - platform: state
    entity_id:
      - sensor.easee_home_XXXXX_status
condition:
  - condition: time
    after: "22:00:00"
    before: "06:00:00"
action:
  - if:
      - condition: state
        entity_id: binary_sensor.pricenanalyzer_five_cheapest_today
        state: "on"
    then:
      - service: easee.set_circuit_dynamic_limit
        data:
          device_id: xxxxxxxxxxxxxxxxxxxx
          currentP1: 12
    else:
      - service: easee.set_circuit_dynamic_limit
        data:
          device_id: xxxxxxxxxxxxxxxxxxxx
          currentP1: 0
mode: single

Neat!
This requires some more templating, though. My suggestion would be to re-use some of the template code from this wiki page( the {{tonight.is_in_cheapest_hours}} variable) to make a binary sensor, which will turn on, whenever we are in on of the 5 cheapest hours between 22 and 0700 (change the template if you want 0600). Test the template in /developer-tools/template in your Home Assistant first.

Then, you can probably just use the binary_sensor as a trigger, and do a if on the same binary_sensor to see if it should start of stop charging, like you did in your example.

You current automation would probably just start charging the car when you connect the charger(when easee_status changes) between 22:00 and 06:00 and only if you plugged it in during the five cheapest hours, as the automation does not trigger again after you plugged it in ?

Don't hesitate to ask if you need more help: -)

I need some help to make the binary sensor from the five time stamps the template output:

I found a finnish person who have made a binary sensor with only the lowest time stamp (https://www.creatingsmarthome.com/index.php/2022/09/17/home-assistant-nord-pool-spot-prices-and-how-to-automate-devices-for-cheapest-hours/).

Sorry I did not read good enough. For making the binary sensor I need only this variabel {{tonight.is_in_cheapest_hours}}.
So I have made the template binary_sensor "binary_sensor.pricenanalyzer_five_cheapest_tonight" with this template:

template:
  - binary_sensor: 
      - name: "Pricenanalyzer five cheapest tonight"
        state: >
          {% set today=state_attr('sensor.priceanalyzer_kr_sand', 'raw_today') %}
          {% set tomorrow=state_attr('sensor.priceanalyzer_kr_sand', 'raw_tomorrow') %}
          {%-set nowTime = now().hour-%}
          {% set tonight = namespace(values=[], sorted = [], five_cheapest = [], is_in_cheapest_hours = false) %}
          {% for hour in today %}
            {% if hour.start.hour >= nowTime and hour.start.hour >= 22 %}
              {% set tonight.values = tonight.values + [{'start':hour.start,'end':hour.end,'value': hour.value}] %}
            {% endif %}
          {%- endfor -%}
          {% for hour in tomorrow %}
            {% if hour.start.hour <= 7 %}
              {% set tonight.values = tonight.values + [{'start':hour.start,'end':hour.end,'value': hour.value}] %}
            {% endif %}
          {%- endfor -%}
          {% set tonight.sorted = tonight.values |sort(attribute='value') %}
          {%for hour in tonight.sorted%}
            {%if (tonight.five_cheapest | count)  < 5%}
              {% set tonight.five_cheapest = tonight.five_cheapest + [{'start':hour.start,'end':hour.end,'value': hour.value}] %}
            {% endif %}
          {%endfor%}
          {%- for hour in tonight.five_cheapest %}
            {%-if now().hour == hour.start.hour %}
              {% set tonight.is_in_cheapest_hours = true %}
            {% endif %}
          {%- endfor %}
          {{tonight.is_in_cheapest_hours}}

Could this template be more simplified?

I only want to have the prices from 22:00 to 06:00, but if I read the code in the template it takes the prices from now to 22:00 and compare the prices to find the best prices. Is this correct?

{% for hour in today %}
  {% if hour.start.hour >= nowTime and hour.start.hour >= 22 %}
     {% set tonight.values = tonight.values + [{'start':hour.start,'end':hour.end,'value': hour.value}] %}
  {% endif %}
{%- endfor -%}

[erlendsellie]

Yeah, you are correct!
It will use the time now, if the time now is over 22:00. Useful if you come home and want to charge your car at 00:00 for example, and the lowest price was at 22:00 and has already passed. If you don't want this behavior, you can just remove the 'hour.start.hour >= nowTime and' part.

Maybe the template can be simplified, but i'm not really an expert at templating.

Thanks, then I use the template like you have made it. Thanks for the feedback.
