Problem getting sensor attributes into voice assistant

I am trying to get the weather forecast data into my voice assistant pipeline.
First I tried to run a script that will call the weather forecast action on demand. I saw the service to be called, but did not get the actual values into the pipeline.
So now I did another way and created a template sensor, that (when triggered) pulls weather data and fills sensors:


Which works on creating the sensors:

But the assist doesn’t seem to have access to the attributes:

So it uses the right sensor and picks up temperatur, but “ignores” all other data.
What could be wrong in regards to my config?
