Configuration

Hi !
I want execute a shell command wth 2 paramaters, I don’t know how

command I want to send

echo -e -n "So,num,cmd\n"  > verif.txt

where num and cmd are parameters
I tried diffrent syntax like this

send_so: "echo -e -n 'So\,"{{num}}"\,"{{cmd}}"\n' > verif.txt"

and the script who call this

service: shell_command.send_somfy
data_template:
  num: 1
  cmd: D

Is it possible ?
Thank’s

I find that writing and calling a shell script is best to avoid issues.

myscript:

#!/bin/bash

echo -e -n "So,$1,$2\n" > /config/verif.txt

configuration.yaml:

shell_command:
  test_params: /config/myscript {{num}} {{cmd}}

scripts.yaml:

test_param:
  sequence:
    - service: shell_command.test_params
      data:
        num: 1
        cmd: 2

Call the service:

service: script.test_param

Output:

rcoleman@rcoleman-linux ...docker/ha/config % cat verif.txt     
So,1,2

BTW, data_template: was deprecated many years ago.

Thank @rccoleman for your fast answer

  • I create a file inside the config dir with name myscript and copied the bash
  • I copied your shell-command in configuration.yaml
  • I copied test param at the end of script.yaml
  • I restarted HA

When I call the service script.test_param in developer tools
I receive the message : failled to call service script.test_param. Unknow error Failled to call service

You’ll need to review the HA logs. One possibility is that you didn’t make the script executable.
