Command line sensor with multiple attributes (solved)

Configuration
1

Hi guys,

I’ve got a device I can access via a python script and get a json answer with a status of 8 switches.
This is an example of returned string with a json structure:

{"1": "1", "2": "1", "3": "0", "4": "0", "5": "1", "6": "0", "7": "1", "8": "0"}

If the device doesn’t response after a given timeout my script returns simple “unavailable”

In the config I have following setup:

sensor:
  - platform: command_line
    name: iteraswitch
    command: >
      python3 /config/custom_components/iteratec/switch.py 0 status json
    json_attributes:
      - 1
      - 2
      - 3
      - 4
      - 5
      - 6
      - 7
      - 8
    value_template: >
      {% if value == "unavailable" %}
        {{ 'off' }}
      {% else %}
        {{ 'on' }}
      {% endif %}

Unfortunately I cannot get the attributes to be stored in the sensor. The sensor hasn’t got any attributes at all. I tried to list the attributes with equation marks like - “1” or switch to string like - “a” (with updating the script code accordingly) but nothing works.

Do you know where I make a mistake?
Any suggestion from your side would be very welcome - thank you!

Hrmm, if the device is a switch, why use a sensor?

In order to get a status of all 8 switches integrated in this single device with just one query.
As far as I know switch does not support json attributes.
And I do have config for the switches for example:

  - platform: command_line
    switches:
      itera07:
        friendly_name: iteratec07
        command_on: >
          python3 /config/custom_components/iteratec/switch.py 7 on raw
        command_off: >
          python3 /config/custom_components/iteratec/switch.py 7 off raw
        command_state: >
          python3 /config/custom_components/iteratec/switch.py 7 status raw
        value_template: '{{ value == "1" }}'
        icon_template: >
          {% if value == "1" %}
            mdi:toggle-switch
          {% elif value == "0" %}
            mdi:toggle-switch-off
          {% else %}
            mdi:lightbulb-off
          {% endif %}

In this case the script returns just 0, 1 or “unavailable” string (let’s say in a “raw” data format).
What is wrong with the sensor?

Cheers

@petro

Hi Petro, I saw your answer here. Would be so kind and check my problem described in this thread?

wrap your json_attributes in quotes

Hi Petro, please accept my apologies for bothering you with a direct call :frowning:

Anyway you motivated me to test the config in more details.
I tested this already with quotes and it did not work, as mentioned in the first post.

The problem however was in the way how I defined the sensor in the config, which I did not share with you to reduce size of the post. So the full sensor code was:

  - platform: command_line
    name: iteraswitch
    command: >
      # Call switch with dummy 0 and json .... bla bla 
      python3 /config/custom_components/iteratec/switch.py 0 status json
    json_attributes:
      - '1'
      - '2'
      - '3'
      - '4'
      - '5'
      - '6'
      - '7'
      - '8'
    value_template: >
      {% if value == "unavailable" %}
        {{ 'off' }}
      {% else %}
       {{ 'on' }}
      {% endif %}

… and the problem is at the line
#Call switch with dummy 0 and json … bla bla
Apparently a comment cannot be used at this place. The python script was simply not executed.
When I removed this comment everything started working as designed.
Many thanks for keeping me motivated :slight_smile:
