A device group is one device that drives many — "All ground-floor lights" as a single switch. Once created, a group appears and behaves like a normal device everywhere: in its room, in its category, on views, in scenarios and in automations.
🏷️ Availability: Device groups are created in the HyperVisu app and the web app; the admin panel has no group editor. Only administrators (access level 5) see the Device groups menu entry; the groups themselves are visible to everyone as normal devices.
Creating a group
What you need: an account with access level 5.
- Open Configuration → Device groups and tap Create a group.
- Enter a name and tap Choose an icon.
- Tap Add Devices. Tick every device the group should hold, in one go, then tap Add n device(s). What these first devices share decides what the group can control. After this first batch, the picker offers only devices that can do everything the group already does — a note tells you when others are hidden ("6 compatible device(s) — 3 of other types are hidden").
- Check WIDGET PREVIEW at the bottom of the editor: it states what the group controls, for example "on/off and brightness".
- Choose where the group appears: its Room and Category. "A group lives in one room and one category, like any device." The app pre-fills them from the members; if the members span several rooms, pick the room where the group itself should appear.
- Tap Save. The app confirms with "Group created". Nothing is stored before you save.
📘 Note: "What type of devices this group controls is fixed once you save it. To change it, create a new group."
What controls a group offers
A group offers only what all the devices of its first batch share. A lighting group of dimmers offers on/off and brightness; tick a plain switch together with the dimmers in the first selection and the group offers on/off only. Once a group has brightness, a plain switch is no longer offered, because it cannot dim.
After saving you can still add compatible members, remove members, rename the group and move it to another room or category. What it controls stays fixed.
📘 Note: A command sent to a group reaches every member, including a member that is excluded from global commands.
How the group's state is shown
In plain language:
- An on/off group shows ON as soon as any member is on — so "All ground-floor lights: ON" means at least one light is on, and turning the group off really turns everything off.
- A level (brightness, position) is shown as the average of the members.
- A mode is shown only when all members agree — otherwise the group shows no mode.
These rules are fixed; the group editor has no setting for them.
Deleting a group
Open the group from the groups list, tap the bin icon in the editor and confirm Delete this group?. Only the group is removed: "The devices themselves are not affected." The group also disappears from any view that showed it.
