Hello everyone 
I created my first template to get weather based triggers for automations.
It works fine so far.
- trigger:
- trigger: time_pattern
minutes: /1
action:
- action: weather.get_forecasts
target:
entity_id:
- weather.forecast_home
data:
type: hourly
response_variable: stundenvorhersage
sensor:
- name: Temperaturvorhersage der nächsten Stunde
unique_id: temperature_forecast_next_hour
state: "{{ stundenvorhersage['weather.forecast_home'].forecast[1].temperature }}"
unit_of_measurement: °C
However as you can see “stundenverhersage” contains the hourly forecast for the next 24 hours.
It should be easy but I don’t get it running. I want to find the maximum temperature value out of these data. With the side permission, filtered by the current date, so that I get the maximum temperature out of the data of the remaining hours of the current day.
What I did is this:
- name: Maximale Temperatur des verbleibenden Tages
unique_id: temperature_maximum_remaining_day
state: >
{% set max_temp = -999 %}
{% set today = now().date().isoformat() %}
{% for forecast in stundenvorhersage['weather.forecast_home'].forecast %}
{% set forecast_date = forecast.datetime[8:10] %}
{% if forecast_date == today[8:10]%}
{% set max_temp = [max_temp, forecast.temperature] | max %}
{% endif %}
{% endfor %}
unit_of_measurement: °C
Anyone any idea? Probably easy. Unfortunately I am new to home assistant and coding.
I am using the standard met.no weather service.
What I get is the value of the entity = “-999”.
Thank you for your help!
