Does tts.voicerss_say support parsing of {{ states.state }}?

Configuration
1

Hello,

I’ve verified that my syntax is correct by calling a persistent_notification, but I can seem to get tts.voicerss_say to handle pulling the text of a state via a {{ }} call.

{
  "entity_id": "media_player.bedroom_wink",
  "message": "states('sensor.ring_cams_offline')"
}

This results in tts.voicerss_say not even processing the string “test”.

I’ve referred to https://www.home-assistant.io/cookbook/notify_if_over_threshold/ to learn the proper syntax.

Is this possible? If so, what is wrong with my syntax?

Thanks,

Matt
