I got a few M5 Atom Echos running. I also linked one to my Google Home Mini in the Office as an external speaker.
As I don’t have an Alexa or Google Home in my living room, I want to send the response as a notification text to my LG TV.
I just don’t know how to grab the response text. Is there a special entity or attribute for this?
on_tts_start (Optional, Automation): An automation to perform when the voice assistant has started text-to-speech.
The text to be spoken is available to automations as the variable x.
Thank you for your help.
I saw my mistake: I added the notification to the on_tts_end part and was wondering why I got the the path of the .wav file as a response.
After adding it to on_tts_start it works fine!
Just in case somebody needs it, here is my code. Simply edit your API KEY, OTA Password, notification device and external media player:
