Split groups (Helper Groups (UI))

Configuration
1

Instead of using the yaml-based groups i added all groups as helper groups.

In node-red i was using the “get-entities” to get all e.g. lights that are on using the “in group” option.

How can i achieve the same with the helper groups?

hi,
I have also tried this and found the following solution:

{% set groupname = 'switch.switch_group_1_camera_internet_access' %}
my group is: 
+ {{ groupname }}

state of (helper-)group switch:
+ {{ states(groupname)  }} 

extended list of group members:
+ {{ expand(groupname) }}

list1 of group member entity_ids
+ {{ expand(groupname) | selectattr('state','eq','on') | map(attribute='entity_id') | list }}

list2 of group member entity_ids
{% for memb in expand(groupname) | selectattr('state','eq','on') | map(attribute='entity_id') | list %}
+ {{ memb }}  
{% endfor %}

this is what I tested with the template editor.
