No TTS via Rhasspy w/REST API

Configuration Voice Assistant
1

I’m not receiving output from my speaker when I test the a rest_command.tts service through hassio.

image

my configuration.yml is as follows:

rest_command:
  tts:
    url: http://192.168.0.n:12101/api/text-to-speech
    method: POST
    payload: '{{ payload }}'
    headers:
      content_type: 'text/plain'

The logs on my rhasspy are:

[INFO:78300838] quart.serving: 192.168.0.n:34294 POST /api/text-to-speech 1.1 200 0 319763

[DEBUG:78300622] EspeakSentenceSpeaker: ready -> speaking
[DEBUG:78300525] EspeakSentenceSpeaker: ['espeak', '-v', 'en', '--stdout', '']

However running the following curl command works
curl -X POST -d "hi world" http://192.168.0.n:12101/api/text-to-speech

The logs on my rhasspy are:

I had the same problem. Finally solved it, using this post as inspiration:

https://community.home-assistant.io/t/solved-send-command-from-ha-to-rhasspy/180704

The service data should not be:

{message: 'hello world'}

but

{payload: "hello world"}

As an example, this automation should notify you via Rhasspy of the hour, every hour. Works on my configuration.

- id: hourlynotification
  alias: hourly notification
  trigger:
  - minutes: '0'
    platform: time_pattern
  action:
  - data_template:
      payload: '{{ now().hour }}'
    service: rest_command.tts
