> Group the devices that live together, such as the bulbs in one ceiling fixture.

_Released 2026-06-26 · Source: https://rematter.app/releases/1.0.17/_

## Group devices that live together

A group holds several devices that are in one place, for example three bulbs in one ceiling
fixture. To make a group, press and hold a device in the list and drop it on another device.
ReMatter asks for a name and suggests one from the room. To add a device to a group, drop it
on the group.

Each group has its own screen, where you can add devices or delete the group. Deleting a
group keeps its devices. They go back to the room list.

You can also choose a group when you edit a device. See
[Group or merge devices](/guides/group-or-merge/).

## Groups in backups

The print sheet shows each group under its room, and backup files keep your groups. See [Print a paper backup of your codes](/guides/print-qr-sheet/).

## A clearer Backup screen

The Backup screen now has two parts. **Print a backup** makes the QR sheet. **Move to a new
phone** exports and restores a backup file. See
[Back up and restore your codes](/guides/backup-and-restore/).
