One of my sensors reports a quoted value as (nested) attribute. I suppose this is why I get None when I call it with a template. Is that true? How can I deal with it?
Templates:
{{state_attr('sensor.oebb_journey_0','retard')}}
{{state_attr('sensor.oebb_journey_0','retard'['dlt'])}}
Results:
{'status': None, 'dlm': '39', 'dlt': '09:09'}
None
