Button-card: call-service notify.<mobile_device>

Configuration Frontend

Hi everybody,

I just played around with companion App. The service call below works perfectly; however, I then tried to wrap it and some helpers in a custom:button-card so that one can send TTS to any android device directly from lovelace.

What am I missing / doing wrong so that it will work? I am using a similar card for local echo devices; however, there I can use service: media_player.play_media, and here I am trying to determine the service to call via template.

Thank you in advance for your help :slight_smile:
