Homeassistant Automation access "Sub-attribute"

1

I know, that I can access a attribute, but what about a sub attribute? How can I use that in an automation.

For example, if I want to get the current temperature I use:

{{ states.weather.dwd_weather_location.attributes.temperature }}

But I have no clue, for example how to access “templow”

weather.dwd_weather_my_location
    sunny	
    temperature: 15.2
    humidity: 81
    pressure: 1027.8
    wind_bearing: 85
    wind_speed: 5.5
    visibility: 12.7

    forecast: 
    - datetime: '2020-09-08'
        condition: sunny
        temperature: 20.4
        templow: 13.9
        precipitation: 0
        precipitation_probability: 1
    - datetime: '2020-09-09'
        condition: sunny
        temperature: 23.2
        templow: 12.3
        precipitation: 0
        precipitation_probability: 3
