In Alert call script via notify

I have a script called “skriptsprachausgabe” which I am calling for voice output on my Echos devices. I have created a notify REST Interface to invoke that script. In the Developer Tools under Service I can successfully call the Rest Service and thus the script, but when I try to include the Notify Service in the alert I get errors and it is not clear to me how to do this. Can someone help me here?

Notify in configuration.yaml

notify:
  - name: skriptsprachausgabe
    platform: rest
    resource: "http://localhost:8123/api/services/script/1698594600049"
    method: POST_JSON
    headers:
      authorization: !secret restapi_notify
      content-type: "application/json"
    message_param_name: message
    title_param_name: title
    data:
      type: "{{ data.type }}"
      duration: "{{ data.duration }}"

Alert

whirlpool_temperatur:
  name: Die Temperatur des Whirlpools ist unter 6 Grad
  entity_id: binary_sensor.whirlpool_temperatur_alarm
  state: "on"
  skip_first: true
  repeat:
    - 30
    - 45
    - 60
  notifiers:
    #- alexa_media_alle_lautsprecher
    - skriptsprachausgabe
      data:
        message: "Achtung: Die Temperatur des Whirlpools ist unter 6 Grad"
        title: "Temperatur des Whirlpools"
        data:
          type: tts
          duration: 6.3

Just a thought (I have no experience with extended notifiers): According to the documentation, the data field is first level (means: has no indentation).

Not sure how this should look like:

But that didn’t help

No, I mean

…
notifiers:
  - …
data:
  …
  …

I have now changed it so that Data is at the top level and now I have no more errors. However, it does not work, no message is output on my echoes. If the Data object is at this level, doesn’t it also refer to notififiers? It should only be set for " - skriptsprachausgabe". Does anyone else have an idea that could help me?

Could you please share the config text pasted into the forum (correctly formatted) rather than pasting images of text. We cant copy and edit your images as easily as text.

See the example here for the format you should be using: https://www.home-assistant.io/integrations/alert/#message-templates

The message key goes at the top level alongside the data key.

(this would have been a lot easier to show if it was text):

In the first post above I have inserted the code accordingly as text, in the answers later I wanted to show the error messages with the pictures, sorry.
I have now changed the alert accordingly. However, I still don’t hear any messages on my echoes but I see errors in the log. It looks like the script is called but the parameters are not handed over correctly. What am I doing wrong?

Since you haven’t shared your script, I don’t know if this approach will work for you, but this is how I use alerts with scripted logic. Instead of using a REST notifier, I use a notify group with an empty set as the value of services. Alerts can be targeted at that notifier, and an automation can be triggered off the service call event created by the alert.

notify:
  - platform: group
    name: scripted_alerts
    services: []

alert:
  whirlpool_temperatur:
    name: Die Temperatur des Whirlpools ist unter 6 Grad
    entity_id: input_boolean.ztest_new_bool
    state: "on"
    skip_first: true
    repeat:
      - 1
      - 2
      - 3

      - scripted_alerts
    message: "Achtung: Die Temperatur des Whirlpools ist unter 6 Grad"
    title: "Temperatur des Whirlpools"
    data:  
      type: "tts"
      duration: 6.3

automation:

          title: "{{trigger.event.data.service_data.title}}"
          type: "{{data.type}}"
          duration: "{{data.type}}"

EDIT: Modified action to reflect OP’s script call.

That looks very interesting. I can then call my script in the action part instead of directly calling the echo. Cool, I’ll try it out!

It worked and I got the message on at least one Echo. However, I still have an error in the log. Not sure what this mean and how to solve.

Does nobody have a hint how to find the problem which variable is NULL? In the forum I have read that this often occurs with template sensors but the error is thrown by the echo “Alex” and here I have no template sensor so a variable does not seem to be passed but which one?

Are any of your echoes Gen 1 or 2… I have one Gen2 dot in our Guest room and it doesn’t have the volume_level attribute, so your variable definition for messagevolume would render a Nonetype + float. Add a float(0) to handle the None.

Filters functions take precedence over mathematical operations so make sure to use parentheses for proper distribution:

  messagevolume: "{{ (state_attr(target, 'volume_level')|float(0) + 0.1) | default(0.6, true) }}"
  reset: "{{ state_attr(target, 'volume_level') | default(0.5, true) }}"

Sorry that I am only replying now after such a long time!
The original error was fixed by your tip but unfortunately I have another error. Can someone help me here again?
