What is wrong in this automation?

I am trying to create an automation which will speak the next sunrise and at the same time will send a message to my smartphone.

    - service: tts.google_translate_say
      entity_id: media_player.home
      data: 
        message: Tramonto. Il sole sorgerà domani alle {{ states.sensor.nextsunrise.state }}.

The message in my phone is working good, while the TTS is not telling me the exact hour of that sensor but will speak just the name of the sensor…
What is wrong?

data_template

Arghhhh… yes, you’re right !!!
Thanks…
