Hello!
does anybody know if it is possible to visually alter a certain entity right from the frontend? this is the use case: all my window covers are grouped under the group covers. This works most of the time, but when I have gusts staying over, I don’t want to automatically command the cover in their room.
Could I visually display a certain group, and toggle on and off the entities that comprise that group?
thanks
There’s no standard card for that.
An alternative would be to use an input_boolean to indicate when a guest is present and then have an automation remove/add the guest room’s cover from the group based on the input_boolean’s on/off state.
However, the group would need to be a YAML-based (“old-style”) group and not a Cover Group (like the kind created using the Helpers menu) because (currently) there’s no service call to manage the membership of groups created via the Helpers menu.
Oh damn 
thanks however for your detailed information!!
