Ntfy notification via CLI/CURL does not work

Configuration
#1

Hey there.

I’ve tried to add ntfy as a notification service to my Home Assistant instance. I wrote a command-line script, that takes either STDIN or CLI arguments as input and then uses curl to my self-hosted notification server. For debugging purposes it even sends out a notification even if the message is missing. Everything works fine when I ssh into my HA and run the script from command line (execution rights are fine). But whatever I try, I seem unable to use this as a notification service in HA.

I’ve tried multiple variations of this configuration:

notify:
  - name: ntfy
    platform: command_line
    command: /root/ntfy.sh

It does show up in the dev section, and I can trigger it without errors – but no notification is sent. Does anybody have an idea what I am doing wrong? Did I miss something?

I have still to try shell_command as suggest in some other threads – if I understand it correctly, I would lose the ability to notify with a custom message. But I might be wrong here.

Thanks!

Did you manage to integrate ntfy in the end?

#3

No, sadly not. I switched to Pushover.

I’m not sure if this meets your requirements, but here’s what it looks like to me.

notify:
  - name: ntfy
    platform: rest
    method: POST_JSON
    data:
      topic: secret-topic
    title_param_name: title
    message_param_name: message
    resource: https://ntfy.sh

In the node-red addon I configured node-red-contrib-sse-client for incoming ntfy messages. But the ‘websocket in’ node works for that too.

I am trying to send ntfy.sh via HA. It works fine with the title and body, but I can’t send the priority and tag. Here is my configuration:
notify.yaml

- name: ntfy
  platform: rest
  method: POST_JSON
  data:
    topic: test 
  title_param_name: title
  message_param_name: message
  resource: https://ntfy.sh

script:

alias: Test ntfy
sequence:
  - service: notify.ntfy
    data:
      message: Nachricht
      title: Titel
mode: single

Tag and priority work in Tasker with this command:

But not in HA. I have tried the following:

alias: Test ntfy
sequence:
  - service: notify.ntfy
    data:
      message: Nachricht
      title: Titel
      data:
        priority: 2
        tags: test, warning
mode: single
icon: mdi:message-alert

and things like:

      message: Nachricht
      title: Titel
      data:
        data:
          priority: 2
          tags: test, warning

The messages are sent, but without the properties. Does anyone have any ideas?

There are a few examples, which may help you:

Thanks! If I see it correctly, priority and tag can only be defined in notify.yalm. I would like to include it in the script or automation.

#8

I didn’t tried it myself. There is a Matrix group for ntfy. I guess, there you have the biggest chance to get an answer, because ntfy isn’t widely known yet.

#9

I’ll try it, thank You.

It is possible to send the service with all its properties via the terminal using curl, which works like this:

curl -d "Hi" ntfy.sh/topic -H "tags: test" -H "priority: 4" -H "Title: Titel"

But now I don’t always want to send the same message via a ‘shell_command’ in the configuration.yaml. How could I fill the command with variables? I can create the command line by:

{% set cmd = "curl -d " + now().strftime('%Y%m%d') + " ntfy.sh/topic -H 'tags: test' -H 'priority: 4' -H 'Title: " + states('sensor.value') + "'"  %}
{{ cmd }}

But: how do I execute it in a script? :man_shrugging:

I have solved the priority issue by creating two entries in configuration.yaml

notify:
- name: ntfy_urgent
  platform: rest
  method: POST_JSON
  data:
    topic: test 
    priority: 5
  title_param_name: title
  message_param_name: message
  resource: https://ntfy.sh 

- name: ntfy
    platform: rest
    method: POST_JSON
    data:
      topic: secret-topic
    title_param_name: title
    message_param_name: message
    resource: https://ntfy.sh

the first for urgent notifications and the other for normal ones.
it works very well it skips in DND mode on my android phone

If you configure your ntfy rest_command with templates, you can override the values when the service is called. So start by adding this to your configuration:

rest_command:
  notify_phone:
    url: https://ntfy.sh/<put your topic here>
    method: POST
    headers:
      title: "{{ title }}"
      priority: "{{ priority | default('default') }}"
      tags: "{{ tags | join(',') }}"
    payload: "{{ message }}"

Then, and automation like this will send a default priority notification:

service: rest_command.notify_phone
data:
  title: Heater pump has been running long
  message: is it clogged?
  tags:
    - warning

And this will send an urgent one:

service: rest_command.notify_phone
data:
  title: Water sensor detected water
  message: {{ trigger.to_state.name }}
  priority: urgent
  tags:
    - droplet

(I haven’t actually seen the water sensor one work - but I have the same templated message for an HA notification that does work.)
