Attributes have null as value

[majkers]

Hi,

here is my config:

var:
  gaz1:
    friendly_name: "Rachunek za gaz"
    entity_picture: '/local/rachunki/pgnig.png'  
    initial_value: '2022-07-11'
    attributes:
      do_zaplaty: '449,70 zł'
      czy_oplacony: 'nie'

And this is what I see in HA:

So attributes get null as value...

[majkers]

Maybe this is related?

invalid key: "OrderedDict([('449,70 zł', None)])" in "/config/configuration.yaml", line 807, column 0

[snarky-snark]

Perhaps a text encoding issue? What happens if you change '449,70 zł' to '449,70?

[majkers]

No, still the same

Have the same issue with attributes

If you post more details about your problem, we may have a better chance of determining the cause.

Have this config

var:
  lexman_1_data:
    friendly_name: "Lexman 1 data"
    initial_value: '{"current_light": ""}'
    attributes:
      scene_1: '{{ {"counter": 1} }}'
      scene_2: '{{ {"counter": 2} }}'
      scene_3: '{{ {"counter": 3} }}'
      scene_4: '{{ {"counter": 4} }}'

Wanted to store simple json

Okay, I think I know what is happening here. Variable attributes are templates, and they are only updated when a tracked event fires. Neither of your variables specify any tracked events, so the attributes are never evaluated.

You can fix this by specifying the following tracked event which will update your variable attributes when home assistant starts.

tracked_event_type: homeassistant_start

Alternatively, you can set the attributes using the var.set service.

As an aside, this behavior can be inferred from the documentation, but it is not obvious. A proper fix for this is to create a separate attribute_templates property for templates and leave attributes for values only.

OK but how about reloading this integration? By watching this event, reloading rom YAML section won't work right? This is essential for my and the reason why I wanted to switch to your integration from similar...

[majkers]

OK but how can I pass component attribute?

[snarky-snark]

I am not sure what you are asking.

[majkers]

This event (COMPONENT_LOADED) requires additional data to be passed -> component (Domain of the integration that has just been initialized. Example: light.) How can I pass it from your integration?

[snarky-snark]

The domain of the Variable component is var.

[majkers]

Yes I know that but how can I pass this param via var integration? tracked_event_type: COMPONENT_LOADED and then what?

[snarky-snark]

Ah, I see. That is not supported at the moment.

There might be another way to solve your problem, but I'm not sure I understand your use case.
