I am playing with the new Watson TTS component and rather than write a script I wanted to see if I could get Watson to interact through my Sonos setup using Node-Red.
Here is what I have so far: https://pastebin.com/Yr3WGnym
It seems to interact with the selected Sonos speaker, playback of existing content stops but I and not getting any speech.
Has anyone else tried TTS through HA - am I better off just bypassing HA for this and going direct from Node-Red to TTS?
Try this script, it TTS and resume playback after:
sonos_say:
sequence:
- service: sonos.snapshot
data_template:
entity_id: media_player.sonos_speaker
- service: sonos.unjoin
data_template:
entity_id: media_player.sonos_speaker
- service: media_player.volume_set
data_template:
entity_id: media_player.sonos_speaker
volume_level: "{{ volume }}"
- service: tts.watson_tts_say
data_template:
entity_id: media_player.sonos_speaker
message: "{{ message }}"
- delay: '00:00:01'
- delay: >-
{% set duration = states.media_player.sonos_speaker.attributes.media_duration %}
{% if duration > 0 %}
{% set duration = duration - 1 %}
{% endif %}
{% set seconds = duration % 60 %}
{% set minutes = (duration / 60)|int % 60 %}
{% set hours = (duration / 3600)|int %}
{{ [hours, minutes, seconds]|join(':') }}
- service: sonos.restore
data_template:
entity_id: media_player.sonos_speakerThats pretty much what this flow is doing - its sort of based on various existing TTS scripts that are on the forums.
Watson TTS doesn’t work for me at all. Can anyone shed some light?

I read something somewhere about using a different regional URL - I can’t remember where but I think logins may be geographical.
Mine is not working either.
Ahh… yes the docs mention a URL as a configuration variable. There is no indication of what it is or that it is required though…
Look on your Watson TTS dashboard and it does give you a URL.
I’ve added mine to my config but don’t have time to restart and try it out now.
If this is the solution the docs are seriously deficient. In which case I’ll suggest an improvement.
Let me know if you try this and if it works.
EDIT: It worked for me but so far in the very few tests I’ve done the Watson voice is a little underwhelming.
I’ve found my problem I am running under docker and the watson component was using the internal address of the docker container to pass the stream to sonos. Sonos could not route to that address. I have used the http: comoponent to route all external calls through the traefik load balance using https:// . I can now play watson tts.
I am trying to use a wait until node to check if the media player has finished playing - this does not seem to be working yet.
