Please help to extract data from a json

Configuration
1

I’m trying to make a sensor that extracts data from a Json specifically the ““Uso CPU”” but I’ve been trying with templates for a week and there’s no way, I always get the message “UndefinedError: ‘value_json’ is undefined” I’m already desperate

Could anyone help me?

the json is very extensive because it is from openhardware monitor

ID 59

I get the json from a local ip http://10.128.99.7:8085/data.json

Please post your config.

Do you mean configuration?

rest:

among a million more variants

en https://jsonpathfinder.com/ this route comes out

x.Children[0].Children[1].Children[2].Children[0].Value

4

Use JsonPathFinder to help you get the correct path to the desired key and value.

For example, to get Uso CPU

Screenshot from 2022-03-24 16-23-12
Screenshot from 2022-03-24 16-23-121839×855 120 KB

the path is x.Children[0].Children[1].Children[2].Children[0].Text which for Home Assistant (in a REST or Template Sensor) would be:

value_template: '{{ value_json.Children[0].Children[1].Children[2].Children[0].Text }}'

If you want the associated Value key (which contains 1.4%) then use this:

value_template: '{{ value_json.Children[0].Children[1].Children[2].Children[0].Value }}'

A potential problem here is that the information is contained in lists and the desired item (Uso CPU) might not always be in exact same location the next time fresh data is received.

I had already tried that before, just what you put, but it keeps getting “UndefinedError: ‘value_json’ is undefined”

rest:

If I just try this:

rest:

still getting the same error

What am I doing wrong?

by the browser and home assistan access the local IP fine

The structure of the example you posted is invalid; it doesn’t conform to the example in the documentation.

Here are two ways to define a REST sensor.

Like this:

rest:
  - resource: http://10.128.99.7:8085/data.json
    sensor:
      - name: example 1
        value_template: '{{ value_json.id }}'

Or using the RESTful integration

sensor:
  - platform: rest
    resource: http://10.128.99.7:8085/data.json
    name: example 2
    value_template: '{{ value_json.id }}'

This should work
attention(when I remember right), only 255 characters allowed in the output

  - platform: command_line
    name: LoremIpsumestdolor
    command: "curl -JsL -m 5 --retry 5 -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36' 'https://pastebin.com/raw/HwCzut36' | jq .Children[0].Children[1].Children[2].Children[0].Value"

this is with the same technique one of my sensors

in all 4 examples above it keeps getting “UndefinedError: ‘value_json’ is undefined”

This on not how the template editor works.
You have to set these up for example in configuration.yaml under sensors:

THANKS A LOT!!!

what a fool I am, a week of work and in the end it was silly that I tried the sensor in the template editor.

she thought it would work there

it works now

what I said, thank you all, it works

the problem now is that when passing the value to int or float it returns “0” I don’t know why

I have tried:

value_template: ‘{{ value_json.Children[0].Children[1].Children[2].Children[0].Value | float}}’
value_template: ‘{{ value_json.Children[0].Children[1].Children[2].Children[0].Value | int}}’
value_template: ‘{{ value_json.Children[0].Children[1].Children[2].Children[0].Value | replace (’ %’, ‘’) | int}}’
value_template: ‘{{ value_json.Children[0].Children[1].Children[2].Children[0].Value | replace (’ %’, ‘’) | float}}’

returns “0”

I just have one question, if it’s not too much trouble…

123 taras said…

“A potential problem here is that the information is contained in lists and the desired item (CPU usage) might not always be in exact same location the next time fresh data is received.”

Is there any way to make a template that, for example, takes the data from “CPU usage” instead of list?

Thank you very much and sorry if I’m annoying

The purpose of the Template Editor is to test templates. You were trying to use it to test a sensor’s configuration based on the RESTful integration.

Because the value uses a comma as a decimal separator. The float and int filters expect a period, not a comma (and so they fail to convert the value and report 0). Your template removes the % symbol and will also need to convert , to . in order for float to recognize it as a numeric string.

You would have to give up using the jsonpath method and perform a text-search using a regex pattern (it’s more complex than using jsonpath).

to be honest, it would be a nice feature. probably terrible to implement

I said, thank you both very much
