A group name is a small piece of interface design. It should tell someone what will happen before they press a control. The most useful names usually come from the language people already use for the room.
Use the room name first
Begin with a recognizable location, then add the distinction that matters. Living room front and living room side are easier to discuss together than two unrelated labels. Check that someone who did not help create the setup can still understand the names.
Keep individual windows and groups distinct
Make it clear when a label refers to several shades. If kitchen is a group, avoid also using kitchen for one individual window. A consistent naming rule reduces ambiguity when reviewing a control layout or talking through a change.
Test the names out loud
Read the labels as if you were explaining the room to a guest. Short names are helpful, but a short name that needs an explanation has not saved much effort. Ask another household member to point to the windows they expect each group to include.
A good label describes the result, not the history of how the system was set up.
Keep a small record
Save the agreed labels beside your window schedule. If a group changes later, update both records together. This gives an installer, a household member, or your future self a useful reference without relying on memory.
