Curl command_line integration fails

[Ben_Barker]

Hi,
I am running HA OS on a pi4
I have various other command_line integrations that call a curl:

If I call this from the HA command line, it works fine

In the logs, it often does not - but frustratingly sometimes it works fine

Logger: homeassistant.components.command_line.switch
Source: components/command_line/switch.py:133
Integration: command_line (documentation, issues)
First occurred: 07:15:15 (2 occurrences)
Last logged: 17:15:15
Command failed: curl --retry 5 http://various_urls

Any ideas? I can see this question has come up in the past, but not sure it was ever resolved…

Command Line

I suppose that curl is not installed in the “homeassitant container”.
You could turn to pyscript, appdaemon, netdaemon to run in a container where you can install extra packets including curl.

I used AppDaemon recently to install all the stuff needed to run python using selenium with chromium in the Alpine Linux based container.

Curl on hassio

Just follow the documentation on installing on a generic Linux distro. I’ve linked the documentation. Install Raspbian. Install prerequisites according to the official documentation and run the script, again, following the official documentation. When people go off and create tutorials, they become outdated and worthless. Just follow the official documentation and it will work.

Suggests that curl likely is available

However, this post looks like I can debug the problem:

SSH'ing from a command line sensor or shell command

I’ve noticed there’s a significant number of posts looking for help on this topic and the posters all seem to struggle with a few common issues. I realized I’ve been almost copying and pasting my responses on these topics so it seemed like a good case for a community guide. What will this cover This guide will walk through the process of getting a command which ssh’s into another machine to get some simple data ready to be included in a command line sensor. To keep it simple I’ll use the same …

I did a quick implementation of how this can work with AppDaemon:

https://gist.github.com/mdeweerd/b752de149f1af764cecb4724cbfba505

It’s a generic AppDaemon module that you can use to call pretty much any command available in AppDaemons container. The script.yaml file shows two examples with an ls on different directories and outputting to different logs.

With the following AppDaemon configuration you should have access to curl.

init_commands: []
python_packages: []
system_packages:
  - curl

Note: you can add an ‘event’ parameter to provide an event name such as ‘call_script1’ and then add an automation:

alias: DemoScript1
description: ''
trigger:
  - platform: time_pattern
    minutes: '45'
    hours: '1'
condition: []
action:
  - event: call_script1
    event_data: {}
mode: single

Thanks!
I tried the details here:

This seemed to confirm that curl should work…but I will definitely give your idea a look as well - thanks very much!
