attributes on binary_sensor contain unit inside the state

[Mariusthvdb]

Did you read the instructions?

• I have read the README, including the known-limitations section.

The request

when using a template on the attributes of the binary_sensor.knmi_zon, there are 2 issue, of whihc 1 is really of importance since it impacts use of that attribute:

{{state_attr('binary_sensor.knmi_zon','Zonkans vandaag')}}

contains the unit %, which is not as it should.

The attribute really should only contain the value, so we can use it in other Dashboard cards, or even template/automation logic

please consider taking out the unit of the state of the attribute.

compare Buienradar entity for that:

secondary suggestion: consider the attributes names to use underscores and lower characters only. Frontend takes care f showing those correctly, but it would be following HA design better to be able to use:

{{state_attr('binary_sensor.knmi_zon','zonkans_vandaag')}}

thanks for considering

Additional information

this is an example of a config that wont show:

      - type: custom:mini-graph-card
        show:
          graph: bar
        entities:
          - entity: binary_sensor.knmi_zon
            name: Vandaag
            attribute: Zonkans vandaag
          - entity: binary_sensor.knmi_zon
            name: Morgen
            attribute: Zonkans morgen
          - entity: binary_sensor.knmi_zon
            name: Overmorgen
            attribute: Zonkans overmorgen

or eg the bar card:

      - type: custom:bar-card
         title: Kans op zon
        show:
          labels: true
         severity:
           - color: Grey
             from: 0
             to: 25
           - color: Skyblue
             from: 26
             to: 50
           - color: Gold
             from: 51
             to: 100
        entities:
          - entity: binary_sensor.knmi_zon
            name: Vandaag
            attribute: Zonkans vandaag
          - entity: binary_sensor.knmi_zon
            name: Morgen
            attribute: Zonkans morgen
          - entity: binary_sensor.knmi_zon
            name: Overmorgen
            attribute: Zonkans overmorgen

which seemingly shows the correct attribute, but not the graph nor the color... because the value is not as it is expected to be,

I agree it makes sense for automations/graphs that the unit is omitted for state attributes.

Be aware that in your example, comparing Buienradar, you're comparing a state with an attribute (unit_of_measurement) to something that is called extra_state_attributes, used by this integration.

I'm not sure if I want to rename the attributes (underscore), as that would be a breaking change. There are also built-in integrations that have spaces in attribute names, so I don't think it's really an issue.

hi, thanks for your feedback!

sure, I am aware I showed the deducted Buienradar entity, and not an attribute. Was merely trying to bring across the separated unit from the state.

on the naming of the attributes entity_id's: indeed, not a true 'issue' in that it causes a problem. tbh I can not find the exact dev design rules on this in https://developers.home-assistant.io/docs/core/entity#entity-naming

just that it is uncommon to do so.

what they do state in extra_state_attributes is that we should minimize those. so maybe break out those attributes into entities?

but, most importantly: please take out that unit ;-)

I'm a little allergic to "too many sensors", hence setting relevant values into attributes :-)

Version 1.3.7 will be soon available with the fix.
