Execute CURL Command from an Automation

Configuration
1

I have a bunch of CURL commands I’d like to use in some automations. However, I can’t figure out how to get them to run from HA. Every topic I’ve seen on the forums is over 3 years old. Examples given on forum posts talk about adding the curl command to a switch, but current documentation say to make it a sensor. I tried using RESTful, too, but haven’t had any luck there, either.

- platform: rest
    resource: http://10.0.4.90/json/state
    method: POST
    payload: >-
      '{"on":true,"bri":5,"seg"...

- platform: command_line
  name: curl test
  command: >-
    'curl -X POST "http://10.0.4.90/json/state" -d '{"on":true,"bri":5,"seg"...

And this is another one :slight_smile:

If you want to keep your CURL commands maybe this Integration will help you:

I’ve tried to follow this, but keep getting errors like this:

Error rendering command template: JSONDecodeError: unexpected character: line 1 column 43 (char 42)
Error rendering command template: JSONDecodeError: unexpected character: line 1 column 1 (char 0)

I go to that character and it’s part of the curl command, so I don’t know what’s wrong. I can run the raw curl command from the CLI and it works fine.

without showing your Code, it is hard to guess…

I made examples in the OP, but here’s my newest iteration. I have this in my configuration.yaml:

shell_command:
  curl_test: > 
    curl -X POST "http://10.0.4.90/json/state" -d {{input|from_json}} -H "Content-Type: application/json"

and then I try and do this in Development Tools:

service: shell_command.curl_test
data:
  input: '{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}'

and nothing happens.

This works perfectly fine from the command line within HA

➜  ~ curl -X POST "http://10.0.4.90/json/state" -d '{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}' -H "Content-Type: application/json"
{"success":true}#

Just a guess. Maybe “|from_json” is the problem. Did you try it without “|from_json” or try to put your input directly in the curl_test command?

8

I’ll try both. If I put the whole thing in the configuration.yaml entry, how would I call it?

without the data section

configuration.yaml entry:

shell_command:
  curl_test: > 
    curl -X POST "http://10.0.4.90/json/state" -d '{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}' -H "Content-Type: application/json"

Developer Tools:

No error, but it doesn’t work. Same if I put it in an automation as an action and run it from there.

11

Wait, I got it. It works when the whole command is in configuration.yaml

Is there any way to variable-ize it so I only need one entry and can change up the data through an automation?

12

Glad to hear it works now!
Do you need whole json-statement to change or only parts of it?

13

Just the data, between the single quotes.

'{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}'

14

OK, then we are back to your post #6 above.
if try this in Template editor:

{% set input= '{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}' %}
{{ input }}

I get this:

{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}

which is witout single quotes.
Maybe this is the problem?
Try this to check:

shell_command:
  curl_test: > 
    curl -X POST "http://10.0.4.90/json/state" -d '{{input}}' -H "Content-Type: application/json"
15

Ok, and then to call it I do this?

shell_command.curl_test:
data:
  input: '{"on":true,"bri":5,"seg":{"id":0,"i":[0,28,[123,231,213]]}}'
16

That works! Ok, so I was losing the single quote because the input was stripping it, so I need it on the outside of both the curly brackets AND as part of the data entry in the automation…which I may make as input_booleans.

Hello. May I see how you have done it in config yaml. I can get this to work in terminal and need help.

curl -X POST https://shelly-85-eu.shelly.cloud/device/status -d “id=b8d61a855cf0&auth_key=MWRmZGUzdWlk89931ACF8A25FB279F2C51675379D12D2F66E28D49798920EXXB7BEC14AB5620D0C5DD30A590DDC8”

I’m new to the forum, but would like to share my 2 cents:

I had a similar issue with my (less than €10) Sonoff smartswitches. In PC-Active 299 (april/may 2018) Adri Wischmann describes how these devices can be modified into a smartswitch with ESPEasy firmware.

After having tried several possibilities in HA to control these, I ended up with this solution:
In the configuration.yaml I added the lines:

shell_command:
  sonoff1_aan: curl http://your ip/control?cmd=gpio,12,1
  sonoff1_uit: curl http://your ip/control?cmd=gpio,12,0

In the automation you can use the above Shell commands for actions.
No integrations needed!
