Can't split state attribute

Configuration
1

Hi there,
probably for a more savvy user the answer is obvious, but I’m going nuts here right now. I am trying to extract certain values from a attribute of a sensor using split. This method used to work fine for me a while ago in a different template but I can’t seem to get it working again.

The sensor attribute is:

Counts: 
- geometries:
    - id: 7
      name: Eingang
      type: LINE
  id: 12
  info: XLT_LINE_IN_OUT_COUNT
  name: Rein-Raus
  records:
    - counts:
        - id: 23
          name: fw
          value: 0
        - id: 24
          name: bw
          value: 0
      from: 1695027840000
      samples: 1
      samples_expected: 1
      to: 1695027900000

I want to extract the “value” of the counts with the ID 23. using the following template:

{{ state_attr('sensor.personenzahler_einlass_2', 'Counts').split ('value:')[1] }}

It gives me the error message

‘list object’ has no attribute ‘split’

I would very much appreciate some guidance since I am quite new to more complex templating…

Thanks in Advance!

Try

{{ state_attr('sensor.personenzahler_einlass_2', 'records')[0][0].value }}

state_attr returns a list, not a string. So you can either

Find the element in the list (which is a string), such as:

{{ state_attr('sensor.personenzahler_einlass_2', 'Counts')[0].split ('value:')[1] }}

[0] above is just a guess, I’m not sure what number you’ll need in there.

Or cast the whole list to a string

{{ state_attr('sensor.personenzahler_einlass_2', 'Counts')|string.split ('value:')[1] }}

Ok that makes sense thanks!

Unfortunately both of your suggestions don’t seem to work for me.

With the first option I get the error

‘dict object’ has no attribute ‘split’

And with the second (which seems the most sensible option for me) I get the following error:

TemplateSyntaxError: expected token ‘end of print statement’, got ‘[’

Thanks for the suggestion, unfortunately this gives me the error:

UndefinedError: None has no element 0

Could you maybe explain what [0][0] stands for?

[0] refers to element of the list. I misread your example as containing a list in a list so it refers to element [0] of first list and then element [0] of that list.

I don’t have experience with count sensor outputs so If you post the contents of Attributes field for that sensor in Developer Tools > States it would be easier to decipher.

you might be able to do:

{{ state_attr('sensor.personenzahler_einlass_2', 'Counts')[0].value }}

Sorry I’m a complete moron that needs more coffee…

{{ state_attr('sensor.personenzahler_einlass_2', 'Counts')[0].records[0].counts[0].value }}

Oh great, thanks! That work’s like a charm :slight_smile:

I missed out some brackets, should have been:

{{ (state_attr('sensor.personenzahler_einlass_2', 'Counts')|string).split ('value:')[1] }}

But the indexing method is cleaner.
