Can't get AWS SNS notifications to work

Configuration
1

I’m trying to set up Home Assistant to send me SMS messages via the AWS SNS notification.

I have put the following into my configuration.yaml file:

aws:
  credentials:
    - name: name-of-aws-credential
      aws_access_key_id: !secret aws_access_key_id
      aws_secret_access_key: !secret aws_secret_access_key
  notify:
    - service: sns
      region_name: eu-west-1

Now I go to Developer Tools > Services and select Notify.Notify as the service.

In the Service Data (YAML, optional) entry box I put the following JSON:

{
  message: "Test Message",
  title: "Test Title"
}

If I submit this, it works and I get a notification on the Home Assistant app on my Andrioid Phone.

When I expand the JSON to include the SNS arn as follows I cannot get it to work:

{
  message: "Test Message",
  title: "Test Title",
  target: "arn:aws:sns:eu-west-1:nnnnnnnnnnnn:hass-notifications"
}

This fails with the following log entry:

'arn:aws:sns:eu-west-1:nnnnnnnnnnnn:hass-notifications'
Traceback (most recent call last):
  File "/usr/src/homeassistant/homeassistant/components/websocket_api/commands.py", line 133, in handle_call_service
    connection.context(msg),
  File "/usr/src/homeassistant/homeassistant/core.py", line 1235, in async_call
    await asyncio.shield(self._execute_service(handler, service_call))
  File "/usr/src/homeassistant/homeassistant/core.py", line 1260, in _execute_service
    await handler.func(service_call)
  File "/usr/src/homeassistant/homeassistant/components/notify/__init__.py", line 120, in async_notify_message
    await notify_service.async_send_message(**kwargs)
  File "/usr/src/homeassistant/homeassistant/components/mobile_app/notify.py", line 114, in async_send_message
    entry = self.hass.data[DOMAIN][DATA_CONFIG_ENTRIES][target]
KeyError: 'arn:aws:sns:eu-west-1:nnnnnnnnnnnn:hass-notifications'

I kind of get that the python code is looking for a nested structure but I’m not sure what it wants due to the constants used for the keys in the stack trace.

I’m guessing that I enter in Service Data goes into self.hass.data so therefore I need some extra levels in my JSON to get target into the right place.

Can anyone provide a sample of some JSON that would work here? Ideally I could also do with a sample that would work in an automation as well.

Thanks.

Sam problem here. Any luck resolving it?

I was able to get mine working. I may be doing something wrong here but I had to specify the access/secret keys twice and also name the notify’er:

in configuration.yaml:

aws:
  credentials:
    - name: Default Profile
      aws_access_key_id: <MY KEY ID>
      aws_secret_access_key: <MY ACCESS KEY>
      validate: false
  notify:
    - service: sns
      region_name: us-east-1
      name: sns_us_east_1
      credential_name: Default Profile
      aws_access_key_id: <MY KEY ID>
      aws_secret_access_key: <MY ACCESS KEY>

Then when sending a message from Developer Tools -> Services:

Service: notify.sns_us_east_1
Service Data:

{
  "target": "arn:aws:sns:us-east-1:.......",
  "message": "Hello There"
}

4 years later - thank you for this.

It seems that adding the key & secret to the notify section is needed, or at least the docs are not clear how to reference the credentials section correctly.

I removed credential_name from notify to ensure that SNS was not trying to reference 2 sets of credentials

credentials:
  - name: HAonAWS
    aws_access_key_id: KEY
    aws_secret_access_key: SECRET
notify:
  - service: sns
    name: awssns
    region_name: ap-southeast-4
    aws_access_key_id: KEY
    aws_secret_access_key: SECRET
