# Version 1.0.12: The first build

> Scan or type a Matter setup code, sort your devices by floor and room, and print a QR sheet.

_Released 2026-06-20 · Source: https://rematter.app/releases/1.0.12/_

This was the first build that went to testers. It saved Matter setup codes only.

## Save a Matter code

Tap **Scan** and point the camera at the QR code on the device, its box or its manual.
ReMatter reads the code and asks for a name, a room and a floor. If the code is already in
your list, the scanner says so and opens the saved device.

If the QR is gone, tap **Enter code manually** and type the 11-digit or 21-digit pairing code.
ReMatter checks the last digit of the code, so a typing mistake shows before you save. A
device added this way shows **Rebuilt from a pairing code**, because a typed code holds less
than the QR. If you find the sticker later, tap **Scan QR to complete**. See [Typed codes and scanned codes](/guides/typed-and-scanned-codes/).

## Your device list

The home screen sorts devices by floor, then by room. A device with no floor shows under
**Unsorted**, and one with no room under **No room**. You can drag the floors into the order
you want. The search box finds devices by name, room, floor, notes, vendor and code.

## The device screen

Each device shows its QR code. Tap the QR to see what the code holds. From this screen you can
share the QR as an image, edit the details, or delete the device. The details are the name,
room, floor, purchase date, install date and notes.

## Backups

**Print / export QR sheet** makes a printable sheet of all your codes. See [Print a paper backup of your codes](/guides/print-qr-sheet/). Backup to a file was
part of ReMatter Pro, a one-time purchase, in this build. Since version 1.0.36, backup is free.
