Invert alert class for the Zone card?

[patent blade]

Is there a way to invert the alerting for the zone cards? Specifically, I have a door sensor, but for that specific room, I want the card to show alert when it's closed rather than open, since those door are open by default.

Try playing with the entity properties, you can change what the sensor is supposed to be. If that doesn't help you can create a helper entity that inverts it.

I don't think there is a way to define a normally open sensor. (You'd think there would be though...)

create a helper entity that inverts it
Initially, this is kind of what I was thinking. But, I think, in order for the Zone card to ignore the real entity, it would have to be removed from the zone which might not be optimal for the overall setup.

well, I just changed the old sensor to a different type. the icon is inverted, but that's just a detail, at least now there's no notification when the door is open

off

{% else %}
on

{%endif%}``` dunno if this code can be imroved, but it works

I made my own "alerting" cards a long time ago with custom:button-card. Normally closed and normally open was something that I had to account for in its design.

state:
    # This is for NC and currently closed and NO and currently open.
  - value: |
      [[[ if ((variables.normally_closed && entity.state == 'off') || (!variables.normally_closed && entity.state == 'on')) return true]]]
    operator: template
    icon: '[[[ return (variables.normally_closed) ? "mdi:door-closed" : "mdi:door-open" ]]]'
    color: rgb(28, 28, 28)
    styles:
      name:
        - color: rgb(28, 28, 28)
```The normally_closed variable is set to true as default, but setting it to false creates the normally open variant.
