Openweathermap - triggers?

Configuration
1

Hi,

I have some shutters which I want to open if rain is coming.
So I added openweathermap integration to HA, using V3 API.
Now, there are some questions:

  1. I did not find some config option to set the update frequency. 1000 api calls a day are free. what is the default polling interval now?
  2. documentation of openweathermap shows an example of how to use openweathermap.get_minute_forecast. But how to use this for triggers? Where are the results? I added an hourly automation for this, but no glue where these data are stored?
    Best regards and thanks in advance,
    Otto
