Lovelace - Edit query result

Hello everyone,

I could use some help.
I have created a group which only contains helpers.
These helpers are switches.
From this group I would like to know which identity is activated. The name is displayed here.
This already works.

The output is not exactly pretty.
I would like to shorten the names. But I can’t get this to work.
In addition, the result should not be sorted alphabetically.
I would like to delete “Wecker_” and “_werktage” from the result.
I would be very grateful for help.

Hello everyone,

I have already been able to solve this myself.

{{ expand('group.wecker') | selectattr('state','eq','on') |
      map(attribute='name') | list | join(', ') | replace("Wecker_", "") | replace("_werktage", "")}}
