Problem accessing attribute in OrderedDict via template

Configuration
1

Hello,
I try to access the values in my entities via template.
The entity looks like this:

image1548×650 75.1 KB

I created the values via the customize.yaml:

sensor.lena_steckdose_power:
  max: 100
  severity:
    - from: 0
      to: 20
      color: Green
    - from: 100
      to: 1000
      color: Red

I try to get the values defined in the severity attribute


{%for sev in state_attr('sensor.lena_steckdose_power','severity')%}
{{sev}}
{%endfor%}

Then I get the following output:


OrderedDict([('from', 0), ('to', 20), ('color', 'Green')])

OrderedDict([('from', 100), ('to', 1000), ('color', 'Red')])

I am not sure how to get the values direclty like severity[0] or something similar.
The best way would be to get the whole severity as a json. Is there any function to get this?
