How to use sensor entity attributes in widget definition

Third party integrations HADashboard

Edit 2:

Well…looking closer at widget definitions I realize sensor widgets don’t have icons. So, I believe the better way to solve my problem is going to be to find/build a sensor-with-icon widget type, and I imagine i’ll be solving these attribute-reference problems through different means. Still curious if what I was trying to do with at least the friendly name would work, but it’s now less important.

Like what seem like half the questions here I’m currently working on a weather app, but I think this question is simple, I just can’t seem to get to the bottom of it…

Very simply, I have sensors that are working in home assistant with a value, icon, and friendly_name.

I want to use these same values in hadashboard.

So, for instance, a sensor named sensor.forecast_4 has the attributes:

friendly_name: Saturday
icon: mdi:weather-pouring

I believe I should be able to use these attributes in my hadashboard widget definition like so:

forecast_4:
    title: {{ states.sensor.forecast_4.attributes.friendly_name }}
    widget_type: sensor
    entity: sensor.forecast_4
    icon: {{ states.sensor.forecast_4.attributes.icon|replace(':','-') }}

I’ve tried lots of variations
{{ states.sensor.forecast_4.attributes.friendly_name }}
“{{ states.sensor.forecast_4.attributes.friendly_name }}”
{{ sensor.forecast_4.attributes.friendly_name }}
{{ states.sensor.forecast_4.friendly_name }}

And I’m not positive about that |replace(’:’,’-’) to use the mdi icon in the hadashboard format, but just one problem at a time. Most of these variations are throwing:

found unhashable key while constructing a mapping

Is this something I should be able to do?

Thank you!

no you cant use templates in a dashboard.
so you need to give the title yourself.

you could use the icons from homeassistant
you just need this in your dashboard

global_parameters:
    use_hass_icon: 1

but as you see yourselve there are no icons for a sensor widget.
so because you probably want to see an icon change based on the state you want to use the “icon widget”

with that you can have an icon for every state.
